Teaching Kidney Physiology in Inner City Elementary Schools is PhUn!!

Children growing up in historically marginalized communities lack access to many resources that they need to thrive, and in many instances, these circumstances predict the opportunities that they will have in life. Some of the statistics that support these observations: “16 million children in the US live below the poverty line”, “Children of color are more than 2 times more likely to be born into poverty than white children” and “Only about 14% of children growing up in poverty will graduate from college”. These are some of the many reasons that experts believe to be behind the low diversity in the STEM field. I believe that early exposure to good role models could change this dreadful statistics.

When I was given the opportunity to start organizing science outreach efforts in the university department where I work, I wanted to marry two of my passions: physiology and reaching to underserved children. I work at the University of Alabama at Birmingham (UAB), which is located in downtown Birmingham. Most of the students at inner city schools here come from low-income families, and the majority of the students are African American or Hispanic. Many of them have no idea how a scientist looks like and do not realize that science is a possibility in their future.

I partnered with the Birmingham chapter of Teach for America, a national organization that is committed to ending educational inequality in the United States. They put me in contact with teachers at 3 inner city schools near UAB, and I worked with them to start coordinating our visits. The teachers jumped at the opportunity of having physiologists visiting their classrooms, as their students rarely have ever met a scientist in person. We started small, with 1 or 2 classrooms per school, but as we did these visits every year for the last 5 years, the rest of the teachers of that grade would also be interested in our visits. The result is that we now visit 5 classrooms per school, for a total of 3 schools, which means that we reach around 300 students every year. To make this possible, I recruit volunteers among postdocs, grad students, junior faculty members, research assistants and even administrative staff at our department.

On the day of the visit, I divide the volunteers into groups (as many as the classrooms that we will be visiting in the school). Each group has a leader scientist and 3-4 helper scientists that go into each classroom. We start our activities with a short PowerPoint presentation, where we talk about what scientists are, what their role in society is, and we highlight the fact that scientists are regular people, not different from the students in the class. We also briefly review the scientific method, and then, we tell the students about how the kidneys work. The students are divided into small groups (4-5 students/group) and start the hands-on activities. Our activities are focused on kidney damage because that is the focus of our department and our research.

A description of each of the 2 activities follows:

Activity 1: Purpose: to determine which glomerulus is damaged

Materials (per group of students): 2 plastic cups (one labeled “blood” and the other labeled “tubule”), 3 filters with different pore diameter (small, medium and big pores; these are the “glomeruli”), a bag of beads of 2 sizes (small beads are “protein” and big beads are “glucose”; note: the small beads need to be small enough to pass through the medium sized filter but big enough to not go through the small-pore sized filter; similarly, the big beads need to be big enough to go through the big pores of the biggest filter), paper tablecloth and paper towels.

Methods: One of the volunteers fills the cup labeled “blood” with some water and the students are instructed to place the beads into the water. Then, the students place one of the filters on top of the cup labeled “tubule” and then pour the water + beads over the filter. The students are instructed to write down what size of beads passes through that given glomerulus. They repeat the same process with the other 2 glomeruli/filters.

 

 

 

 

 

 

 

 

 

Discussion: Once they are done, the leader explains that normal urine does not contain any protein and that the glomerulus/filter that did not let any bead pass through is a normal glomerulus. Then we explain that when there are small beads in the water, that means that the glomerulus is damaged and that the patient has protein in the urine (we call this acute kidney damage). We also tell them that in a diabetic patient you would find both protein (small beads) and glucose (big beads) in the urine; thus, the filter with big pores is the diabetic glomerulus.

Activity 2: Purpose: Diagnose the kidney disease – Fake urine! The students have to determine which patient is normal, has acute kidney injury or is diabetic.

Materials: 3 small cups with covers labeled “patient 1”, “patient 2” and “patient 3” (we use small histology cups), protein and glucose urinalysis dipsticks (3/group of students), key color chart, Diet Cola soda, albumin, glucose or sugar. Not necessary, but PhUn: gloves and masks.

 

Teaching Kidney Physiology in Inner City Elementary Schools is PhUn!!

To prepare the fake urine (this can be done in advance and kept in the fridge until you take it to the school): For the normal urine – mix water and enough diet Cola to give a urine-like color; for the acute kidney injury urine – mix water, diet Cola for color and albumin; for the diabetic urine – mix water, diet Cola for color, albumin and glucose/sugar. Make each of the urines in big batches and then distribute in the appropriate cups.

Methods: The volunteer helpers distribute 3 cups filled with urine to each group of students, together with 3 dipsticks and a key color chart. The leader tells the students a story about having an MD friend that works at the hospital. The MD is extremely busy and has asked the leader for help to diagnose the patients. The leader tells the students that the urine is from patients at the hospital (there will be a huge “Eeeewwww” coming from the students at this moment). The leader tells the students that they need to wear the gloves and masks because they are doctors for the day and they are working with “human urine”. Instruct the students to dip the dipsticks in the cups one at a time, count to 10 and look at how they change color; with the help of the volunteers, the students write down their diagnosis.

 

 

Discussion: When all the groups are done, the leader summarizes the results for each patient and talks a little bit about how to keep healthy kidneys. Do not forget to tell the students at the end of the activity that the urine was fake!!!

We have found that this activity sparks a lot of interest in the students, since many of them know of somebody with kidney disease due to hypertension or diabetes. Students deeply engage in the activities and ask millions of questions, not only about the kidney and how it functions, but also about our path to science and how a regular day in the laboratory is. Our volunteers are a very diverse group, many of them minorities and from many different countries, so these visits also provide the students with diverse role models in the STEM field.

A decade of PhUn Week fun in Birmingham

Several of the physiologists at the University of Alabama at Birmingham (UAB) have provided considerable time and effort into making PhUn week a great learning experience for K-12 students and teachers in the area. Carmel McNicholas-Bevensee and Kathy Berecek were early PhUn week explorers, taking active learning experiences to the K-5 classrooms in the area, while Mike Wyss conducted both classroom sessions and sessions at the McWane Science Museum in Birmingham. More recently, David and Jennifer Pollock have joined the UAB PhUn week efforts and greatly enhanced its reach.

The original format of UAB PhUn week was to go out to area schools to teach relatively simple, albeit important lessons to K-5 students. Some of the first experiences were to simply take a cow heart to the schools. We quickly realized that the size and weight of a cow heart made the experience difficult, and thus changed to a pig heart-lung preparation, which was more manageable. A plastic tube was inserted into the lungs connected to a bicycle pump, with which the lungs could be expanded with air. For most students this was in itself exciting, but adding to the excitement, the presenter dressed in a white coat and Personal Protective Equipment (PPE) and told the students that as they participated in touch the heart, they too needed to don PPE. We kept the oral presentation short (< 10m), but provided enough background to help the students understand what they were about to experience. Models of the pumping heart, helped the students to gain insight into how blood flows through the pig heart and how the heart worked in them. For middle school students this expanded into 50-minute classroom sessions with human brains, in which the students began to touch the brains and identify major areas.

While many of these experiences were great, one of the most fun experiences is taking the Lung-O-Meter into a grade 2 or 3 classroom. The experience is relatively simple, but teaches several lessons that the teacher can build on. The ingredients are several empty, gallon milk jugs, a plastic tub that has about a > 2-gallon capacity, magic markers, a measuring cup (or graduated cylinder and a flexible plastic tube. The object is to have each team of about 3 students each mark gradations on the milk jug (hopefully in mL), cap the jug when completely filled, turn it upside down, place it in a tub of water remove the cap, place the plastic tube inside the jug, and then blow into the tube to determine lung capacity. The students then put their data points on a graph on the white board in front of the room relative to the student’s weight and height, to estimate whether there is a relationship between these variables. Thus, the lesson teaches them about measurements, scientific process, team work (each student in the group gets an assigned task) and individual differences. Mostly though, it teaches them science can be fun, and what is more fun than 30 7-9 year olds getting to splash around in water in their classroom.

With this or any other similar activity, it is very important to partner with the teacher and administrators in learning experience. Perhaps of prime concern to both groups is that the class time be used to address key learning objectives, typically linked to the Next Generation Science Standards and/or the state’s science course of studies. It is a great benefit for the visitors to explain to the teacher ahead of the visit, the first principles underlying the activity. Grade K-5 teachers often have relatively little formal science background, and thus these PhUn week experiences can be a great learning experience for them as well, as long as they are presented in a collegial way, remembering the visitors can learn much from the teacher about pedagogy of K-5 students. In general, it is best if the PhUn week teams include a faculty-level physiologist, who can help coordinate the activity, but recognizes that the best ideas for the activities likely will come from physiology students/postdocs who design them. Also, the faculty member can often assuage hard feelings when a school cancels an event at the last minute. This will happen and usually relates to emerging situations at the school that are not easily foreseeable.

Just a brief word about mass presentations versus classroom visits. Our presentations at McWane Science Center for both PhUn week and Brain Awareness Week reach a huge number of students in one week (>2,000), especially when they are scheduled for school break periods. However, these events typically do not link up the teachers to the physiologists. Often, once a teacher and physiologist link together in the classroom experience, the teacher is much more likely to engage the physiologist or join in other learning programs that are offered by the physiologist’s institution. Also, the science museum presentations are typically short (2-5 min.) and more focused on the excitement/wonder of science, while the classroom presentations can go more in depth. Over the 10+ years of UAB’s PhUn week, we have reached about >13,000 students in classrooms and >14,000 in the science center.

The engagement of the faculty physiologist also helps researchers address the Broader Impacts that NSF and in part NIH are demanding in applications for research grants. Both granting agencies want to encourage researchers to translate their science to the public, and PhUn week activities can do just that.

A PhUn Week Experience Influenced by Excitement

 

I was initially asked to participate in PhUn Week by a staff member within the American Physiological Society (APS) headquarters. Reluctantly, I agreed to put one more activity on my busy schedule.  As the time approached for the PhUn Week presentation to an elementary school group, an exceptional amount of thought came into what I would present to engage the students.  I don’t exactly remember the minute details of what my first PhUn Week presentation was about; however, I will never forget the enthusiasm and excitement shown by the elementary students once they became engaged and participated in the presentation.  I was immediately convinced that PhUn Week presentations delivered all over the United States were helping to dispel the myth that “science was boring and very difficult.”  As I recall, the PhUn Week presentation caused the students to ask a lot of relevant and also irrelevant questions.  The point was that they were not afraid to raise their hands and to make a comment or ask a question about cardiovascular or renal function.  One memorable moment was the excitement that the participants showed when the trace of their EKGs were displayed upon a screen and their heartbeats were magnified over a speaker system.  As the crowd watched the tracing and heard the sounds of the heartbeats from their brave classmate who volunteered, they simultaneously placed their hands over their heart to feel if their own hearts had a similar beat.  As a result, the number of volunteers tremendously increased and so did their heart rates. During this and other PhUn Week presentations, the initial “ice-breaking” moments opened up the excitement and many possibilities and understanding of physiology.

My PhUn Week presentation experience was not only unique with elementary students, the excitement and engagement was exhibited throughout elementary, middle and high schools. During the various educational stages of the participants, there was something that made them more curious about understanding physiology, which resulted in questions, or something they could relate to and wanted to share with the group.  The responses were observed in classrooms in Augusta, GA, the inner city of Washington, D.C and various suburbs in Maryland.  In my experience, the excitement and curiosity for physiology did not significantly vary, whether the PhUn Week presentations were given to a science interest group or to a gym full of elementary or high school students.  To my surprise, the PhUn Week presentations were also well-received by teachers and administrators.  One would think that the PhUn Week presentations would be an opportunity for the teachers to take a well-deserved break, grade papers or simply prepare for the next class.  Instead, the teachers watched intensely and on many occasions, interjected scientific principles previously discussed in the class.

My preparation and prompts utilized for PhUn Week have evolved over the years. Initially, the presentation depended upon WiFi connections to play videos, the transportation of electronic equipment that would display EKG tracings and speakers for the magnification of heart sounds, to the construction of a urinary system out of plywood, polyvinyl chloride (PVC) pipes and plastic containers. Out of all the PhUn Week presentations, the construction and transportation of the urinary system was the most eventful.  Although, the system was tested, which included pouring a “small amount” of water through a funnel, which was connected to the aorta and the water was divided at an intersection of the PVC pipe to depict the renal arteries and filtered through additional funnels connected to polyethelyne (PE) tubing, to depict the ureters.  The flow of the liquid through the kidneys (the filtering component) down into the ureters, which was connected by considerable amount of clay, was the area of most concern.  On the day of the presentation, and after a brief introduction, I asked for a volunteer to come up on stage to assist me with the process.  My instruction was: to please pour a “small amount” of water upon prompting.  Little did I know that the fourth grader was very excited, and he poured almost a half-gallon of liquid into the urinary system display at one time.  As expected, the ureters, which consisted of PE tubing, could not withstand the large of amount of volume and pressure exerted upon the system.  As a physiologist, we are trained to “think on our feet.” My first action was to stop the flow of fluid, the second was to reinforce the PE tubing funnel connection with more clay.  Paper towels were needed, of course, to clean up the “spill of excitement” on the floor.  During that demonstration, the students were able to successfully see how red “blood” goes through the urinary system to produce a clear or “light-yellow tinted urine.”  The class and teachers were very patient, excited, appreciative, and helpful during this certain PhUn Week presentation.  Now, I often think about other ways in which a hands-on urinary system could have been presented to a group of elementary school students.  Nevertheless, the excitement experienced by everyone that day will go down as one of my most memorable PhUn Week presentations in more ways than one.

Over the years, I have looked forward to the PhUn Week presentations and have been asked to return to certain sites on multiple occasions. The impact and appreciation exhibited by the students, teachers and administrators are tangible: you are making a lasting impression upon young students.  I received numerous e-mails from the PhUn Week participants expressing their gratitude of my presentations, and excitement for the learning of physiology.  My most prized possessions from the PhUn Week presentations are the hand-written cards and letters from the many students.  The most creative cards also include a drawing from the particular presentation, possibly including a spill during the constructed urinary system.  I must say that PhUn Week has generated an exposure to students of all ages for an excitement in the field/possibilities of physiology.  Activities such as PhUn Week are vital for developing and continuing the “pipeline” for the biomedical workforce.  Although the participation in these PhUn Weeks were considered an added event on my schedule, I am convinced that it is very important for the understanding and future of physiology.  I am also energized by the excitement exhibited by the PhUn Week participants, and students.

Years of PhUn Week!

 

My first foray into K-12 education was when I volunteered to my daughter’s second grade teacher to come and do science in her classroom during the year. Since that time thirty years ago and subsequently as the scientist-in-residence for our school district, I have routinely taught portions of first and second grade science, visited all of the seventh grade classrooms with science activities, and gone with my university students to teach renal physiology to high school students.  Thus, getting involved in PhUn Week was not much of a stretch for me.

 

 

 

By this time, I have done PhUn Week with the entire seventh grade annually since 2006. I missed 2005 because I was a guest lecturer at Africa University in Zimbabwe during the fall semester when the PhUn Week pilot was launched.  My initial involvement with PhUn Week was to visit the classrooms of my 7th grade teacher colleague and former APS Frontiers in Physiology teacher Sally Stoll.  Since she taught all 7th grade science and life science was a large portion of her curriculum, we planned an entire unit on physiology that was supplemented by the exercise activities that we offered together for the students.  We started with having the students measure their pulse before and after light exercise and expanded to having the students determine their heart rates, breathing rates, and skin temperatures before and after exercise.  Adding measurement of skin temperature not only brings in the issue of where to measure skin temperature and the concept of where the body thermostat is but also exhibits true homeostasis as while heart and breathing rates increase with light exercise, skin temperature almost always decreases with exercise!  During this collaboration, Ms. Stoll was teaching life science during the fall semester so we could plan PhUn Week around the same time as the national launch in 2005.

 

After Ms. Stoll retired, Maria May (a former student of mine when I taught animal physiology to biology majors) came on as the 7th grade science teacher.  She was perfectly willing to have me come to her classroom and do similar activities with her students; however, due to state and district curricular changes life science is not now the main topic for 7th grade science.  Thus, the effects of exercise on heart and breathing rates and skin temperature is not quite the culmination of an entire unit but still fits into the curriculum during the spring semester.  For the last few years, we have conducted our PhUn Week activities in the spring but signed up for PhUn Week in the fall along with everyone else.  I now spend one whole day doing the exercise activities with the students (teams of students are assigned different types of exercise like running in place, jumping jacks, step tests, and running in the hall), one whole day talking about careers in physiology, and one whole day doing a case study activity diagnosing kidney diseases with fake urine for Ms. May’s students.  The kidney disease case studies were written for the APS by current Education Committee chair Jeff Osborn a number of years ago and I use them routinely with students from middle school through college.

 

Now as an experienced science outreach person, I can verify that all levels of students love science activities. I have even taken science activities to the non-profit day care center on whose board I serve as a summer activity for 3-year-olds on up.  My college students have affirmed to me that they learned renal physiology better by having to teach it to advanced biology and anatomy and physiology high school students.  All science professionals need to be able to communicate their science with others for the future of science and their careers!

A Team Approach for a PhUn Experience that Applies Curriculum-Based Concepts

In the beginning:

From the time my children were in primary school, I visited K1-12 classes and engaged students in various science activities ranging from demonstrations to hands-on activities. In addition to presenting science demonstrations and explaining scientific principles, I wanted to share the discovery process with them and usually concluded my visit by talking about diversity of science careers and explaining how “the lesson” related to subjects they learned everyday in their classrooms.  My science “outreach” continued with sporadic visits to schools, either by myself or with colleagues.  Sometimes, they were in response to requests for faculty to speak to various groups or to help with a science fair.  It was enjoyable to share my interests while working with a wider educational community, hoping to increase awareness of science and what physiology encompasses.  The enthusiasm of the students and teachers made my outreach experiences fulfilling and fun!  As PhUn Week came into existence, it was a natural extension to my classroom activities.  It opened new vistas by providing a network of people, classroom lessons, educational resources and supportive information to increase awareness of physiology careers.

 

New vistas:

In addition to finding teachers and administrators that welcomed PhUn Week, it was essential to first meet with the teachers to develop a physiology-oriented activity. One of my goals was to work in parallel with the classroom teacher to get students to apply science and math they were being taught to the physiology that was presented.  I had not done this to any extent previously and found that it worked very well with teachers who actively participated in the lesson with me.  I introduced myself to the class, explained what physiology is and described various careers physiologists and other scientists have.  A popular topic was how the lungs and heart function together.  We constructed a model with a plastic bottle, tubing and balloons to demonstrate how the lungs inflate and deflate during normal breathing and formulated inquiry-based questions such as, “what causes air movement during normal inspiration and expiration.”  This enabled us to illustrate the relevance of Boyle’s Law and discuss principles of pressure-volume relationships, airflow, ventilation, diffusion, gas exchange and even Bernoulli’s Principle using demonstrations, physical laws and basic math.  Videos with animations downloaded from the internet were used to show gas exchange and how the lungs function together with the heart and vascular system.  Students were divided into groups and guided to develop and discuss a hypothesis related to flow, velocity and pressure relationships in the lungs.  The heart as a source of pressure for blood flow was discussed along with its role in systemic and pulmonary circulation.  In a hands-on group activity, students were taught how to measure blood pressure and to calculate heart rate and breathing frequency.  They speculated about changes they would expect with exercise, measured changes in heart rate and breathing frequency that occurred, and summarized data.  We concluded by discussing benefits of a healthy life style and exercise on heart and lung function.

 

 

 

 

 

 

Following up:

A subsequent follow-up quiz comparing the ability to correctly answer curriculum-based concept questions (without reference to physiology) to questions based on our inquiry activity indicated a positive correlation. We also experimented with  “Before” and “After” questions as a way to get students to apply what they learned to the solution of questions that they formulated.  Responses to the questions were used to assess understanding of physiology and scientific principles that were presented. Scores indicated that hands-on activity increased the classes’ overall performance.  Quizzes also helped to identify concepts that needed further explanation. Teachers provided perspective of the curriculum and accommodated our activity into their lesson plans.  Our team gained new perspectives for developing ways to think about and teach physiology and enjoyed interacting with teachers and students.  Students were very enthusiastic about their PhUn Week experience.  The overall model that we used can provide experience with the scientific method, inferential reasoning, formulating questions, making observations, and collecting data while introducing students to future STEM careers.  Our model is flexible and allows concepts to be taught in interesting ways that hold student’s interest and are relevant to every day life.  It can be scaled up or down depending on the grade level and we learned that collaboration is important for developing and coordinating appropriate activities and questions for the grade level.

 

The strength of collaboration:

In addition to the classroom teachers, our Phun Week activity depended on the collaborative efforts of a diverse team consisting of a physiologist, a physiology graduate student, a graphic artist experienced with information technology and an experienced K1-12 teacher who has participated in APS teacher workshops and poster presentations, taken high school students through the exhibit hall at Experimental Biology meetings, talked to students and got them to talk about career plans. This team approach greatly supported and enhanced the transitions between demonstrations, video presentations and hands-on group activities.  It also made it possible to work with three different classes sequentially on the day of the activity.  The different perspectives of our team members helps to show that science careers also depend on effective communication skills and knowledge of the arts and humanities as well as science, technology, engineering and mathematics.  The University of Louisville is supportive of our community outreach.  At the end of the school year, our PhUn Week activity was followed up by a field trip to the University where three classes visited my laboratory for a demonstration related to our activity and toured educational facilities in the Health Sciences Center.

Our experienced K1-12 teacher (Ann C. Roberts, who is also my wife) provided insight into teaching and learning styles, motivational techniques, incorporating PhUn Week lessons into school curricula, and co-authored our PhUn week perspective. She has good rapport with students and classroom teachers which helps to direct and guide students during presentations and group activities. Ann received her B.S. and M.S. degrees in education at Western Connecticut State College in Danbury, Connecticut.  She received certification in New York, California and Kentucky, has many years of classroom experience in public and private schools and co-authored our PhUn week perspective.

PhUn is What You Make It!

Each year, we celebrate PhUn (Physiology Understanding) Week at a local elementary school in Georgia. Reaching out to elementary-aged students allowed us to surprise and excite young students about the role of physiology in their daily lives. Our goal was to inspire them to have an open mind about who can become a scientist. Studies show that between the ages of 6 and 15, women and minorities lose confidence in their ability to thrive in mathematics and the sciences (1, 2). Therefore, our goal was to demonstrate, to a diverse group of students, that PhUn is what you make it!

 

Our PhUn consisted of 4 phases: 1) Draw a Scientist, 2) Dress a Scientist, 3) Meet a Scientist and 4) The Scientist Within.

 

Phase 1: Draw a Scientist. This phase served as our “Scientific Bias Screening”. The goal was to dispel assumptions about who was and could be scientists.

  • Prior to our arrival, we requested teachers to encourage students to draw whatever they considered a scientist.
  • When we arrived, we allowed students to describe their pictures to the class.

 

This phase was necessary, as it is important to encourage teacher participation since teachers are on the forefront of motivating students daily. Teachers are responsible for shaping and encouraging students to pursue various career opportunities, so having an entire community of teachers to encourage students of all backgrounds (gender, race, socioeconomic, etc.) to pursue STEM fields is critical to promoting awareness of the opportunities and needs within STEM. Furthermore, allowing students to confront their implicit biases about scientists provided a teachable moment.

 

 

 

Phase 2: Dress a Scientist. This phase was important to de-mystify scientific tools and make them relatable.

  • Prior to our arrival, we assembled a “science” bag with laboratory tools (conical tubes, beakers, pipettors, etc.), personal protective equipment (gloves, lab coat, eye googles) and fun items (“crazy” wig). We included items that are used in the typical physiology lab – we decided to leave heavy analysis equipment out of the bag!
  • The teacher selected a volunteer student to be dressed as a scientist.
  • Classmates were asked to name items that the volunteer student needed to “look” like a scientist.
  • After removing the named items from the bag, students were then asked to guess the utility/function of said items. Guiding questions were used to assist.
  • We explained how each item is used and what other purposes it could serve.
  • The item was given to the student scientist to put on or hold.
  • After emptying the bag, students take group pictures with the scientist they dressed.

 

Many students feel overwhelmed and ignorant because they haven’t been exposed to laboratories. Our goal was to allow students to touch and learn about these tools. As a result, science became a lot less foreign and intimidating.

 

Phase 3: Meet A Scientist. The phase served to motivate students to consider themselves capable of contributing to scientific discovery.

  • We introduced ourselves as scientists and explained our areas of research.
  • A picture of a “Mad Scientist” was projected. Students were asked if we looked like mad scientists.
  • Pictures of scientists from diverse backgrounds were then projected.
  • We described our journey to becoming scientists from high school to college to graduate school. We also shared personal stories of our experiences at each level, explaining that determination is the key to success.
  • We posed the question “Do you ever ask why…why…but why?”
  • We explained that scientists use the scientific method to answer the “whys” and that each of them possessed the important quality of being inquisitive and that they were indeed “Scientists in Training”.

 

We were aware that there are multiple reasons students may not be excited about science and scientists – namely it can be seen as nerdy or dangerous. As we clearly do not typify what a “Mad Scientist” appears to be, we aimed to expand the definition what scientist appear to be. The goal was to help them realize that anyone with an interest in learning how things worked can be a scientist.

 

Phase 4: The Scientist Within. This phase was crucial for helping student internalize their ability to be scientists.

  • We described the cardiovascular system in health and disease.
  • Students were then instructed to form a hypothesis regarding blood flow in a healthy blood vessel versus and unhealthy blood vessel.
    • Step 2- Measure 60 ml of the liquid into the cup.
    • Step 3- Start the timer and use the coffee stirrer to suck up and drink all of the liquid from the cup. Be sure you drink until you reach the bottom of the cup. Do it as quickly as you can but only suck the liquid through the coffee stirrer. Stop the timer as soon as the liquid is gone.
    • Step 4- Record the amount of time it took to drink the 60 ml of liquid.
    • Step 5- Repeat steps 2-5 again but this time use the drinking straw to suck up the water.
    • Step 6- Repeat steps 2-5 two more times so you have run each experiment three times. Record the amount of time it took to drink the 60 ml of liquid.
    • Step 7- When you have recorded your data, go to the APS Physiology Understanding Week website (www.phunweek.org) and share your findings with other APS Junior Physiologists.
  • We assisted the students in performing the Healthy Heart Experiment II: Does What We Eat Matter to Our Hearts? http://www.the-aps.org/phun/pdfs/PhizzyPostcard.pdf

 

The students certainly enjoyed this Phase the most! This phase served to teach students about the cardiovascular systems and how science is already an active component of their lives. By showing the students a fun way to perform experiences, we removed some negative stereotypes about scientists and sparked interests in science we hope are lifelong. Most importantly, students were able to identify themselves as scientists and internalize their abilities to thrive in STEM.

Ultimately, we received plenty of participation and interaction with the students and teachers. We were able to surprise and excite students to re-evaluate who could be a scientist all the while, we were also able to encouraged students to believe that they all have the potential to become scientists themselves. Beyond being rewarding, this event was critical to demonstrating how diversity in STEM is critical for recruiting the next generation of scientists. Seeing two minority women be confident, capable, and qualified inspired the students to ask questions they may not have felt comfortable with in other environments. It also allowed them to believe that being a scientist is possible and that PhUn is what you make it!

Dr. Clintoria R. Williams is a renal physiologist. She is a 2001 graduate of Clark University, where she completed a BS in biology. Dr. Williams continued her education at the University of Alabama at Birmingham (UAB), earning her PhD in physiology in 2008. She returned to Atlanta and joined the Emory University School of Medicine as a postdoctoral fellow, where she established her research program.

Dr. Williams’ research interest focuses on the pathophysiology of kidney disease. Her work has identified a key functional difference in the two isoforms of calcineurin, a family of ubiquitious calcium-dependent enzymes. These enzymes contribute to the regulation of sodium channels in the distal nephron and subsequently blood pressure. Notably, patients that take calcineurin inhibitors for immunosuppression frequently develop hypertension. Since current drugs that inhibit calcineurin do not discriminate between the isoforms of the enzyme, there is an opportunity to refine pharmacological interventions to selectively target calcineurin isoform(s) implicated in the immune system versus isoform(s) involved in salt regulation in the kidney. Her work is currently funded by the American Heart Association.

Dr. Williams has been recognized as an outstanding early career scientist by the American Physiology Society, where she has been an active member of several committees. In addition, she was a founding member of the Minority Postdoctoral Council at Emory University and is a passionate mentor of undergraduate and graduate student scientists.

PhUn week 101: New Institution, New Partners

In 2011, I attended the PhUn week workshop at Experimental Biology, where I learned about the program and some of the steps to organize the program. Since then, I have organized a PhUn week activity every year for 6 years now, including at the elementary, middle, and high school levels.

Physiology Understanding (PhUn) week is the American Physiological Society outreach program looking to motivate K-12 students to choose science programs as their higher education path. In the past 5 years, we have developed a series the PhUn week activities from theater-like presentations to high technology hands-on experiments showing how physiology can be integrated to the science curriculum or promoting health care careers.  These activities were performed in the Wabash Valley, IN, area and involved 50 to 100 K-12 students with 8 to 30 college-aged facilitators (undergraduate and graduate).

This year, we had to re-create PhUn week from scratch due to new institution (The University of Texas at El Paso-UTEP), new city (El Paso, TX), and new school district (El Paso Independent School District).  Because of my new position at UTEP, I did not have any direct access to undergraduate and graduate students, except for one senior PhD student and one freshman undergraduate student.  Therefore, we had to start with the basics of PhUn week 101.  First, find a community partner within the school district.  We found it at Dr. Hornedo Middle School’s 6th grade science teacher and a class of 24 children.  Second, recruit undergraduate students willing to dedicate 15 to 20 hours in training, design, and execution within 4-6 weeks.  Six students were recruited from the Bachelors in Rehabilitation Sciences at UTEP.  Third, design a production plan, which begins with a hierarchical model to evolve toward a ‘flat organization model’.  My PhD student and I trained the ‘senior’ undergraduate student in the PhUn week purpose and use of applied technology (i.e. Biopac MP40).  Then, the ‘senior’ trained the remaining 6 undergraduate students.  Once they were all trained in the use of Biopac MP40, we had 2 meetings used for brainstorming and   designing PhUn week activities.  The design of 3 hands-on activities was decided horizontally, within our flat organization, which created a great discussion environment and great new ideas! Once everything was planned, we went to Dr. Hornedo Middle School for a 3-day session.  On the first day, a general description of the program was given and data collected on a ‘reaction time’ activity.  Day 2, data collection in cardiovascular responses to exercise and changes in the electromyogram related to increased workloads.  Day 3, data analysis and review of the results.  The outcomes were successful in many levels: at the school level, children were able to collect data in different physiologic responses (i.e. electromyogram, electrocardiogram, and reaction time) that was used within their science curriculum; at the undergraduate level, students were able to reinforce their social responsibility mentoring school-aged children as role models for a successful college career.  In addition, undergraduate students were able to analyze some of the data and produce 2 abstracts for the PhUn week workshop at the upcoming Experimental Biology meeting and they registered on a UTEP undergraduate science course to explore new career paths within the STEM field; finally, at the Gurovich Lab level, we confirmed that PhUn week is not only fun but tremendously rewarding, as you can change lives and minds of younger generations.

 

Dr. Gurovich received his Physical Therapy degree from Pontificia Universidad Católica de Chile in 1990 and worked as a clinician for more than 15 years in different fields such as sports medicine, cardiovascular rehabilitation, and human performance.  In 2006, he moved to University of Florida where he received his doctoral degree in Health and Human Performance in 2010, and a post-doctoral position at University of Florida College of Medicine, in the Department of Physiology and Functional Genomics, where he learned in vitro and in situ techniques that strengthen his translational research background.  In 2011, he attended the PhUn week workshop at Experimental Biology, where he learned about the program and some of the steps to organize the program. In 2012, he was recruited by Indiana State University to help developing the Doctor of Physical Therapy program.  Since then, Dr. Gurovich has organized a PhUn week activity every year for 6 years now, including elementary, middle, and high school students.

Dr. Gurovich is an active member of the American Physical Therapy Association, the American Physiological Society, the International Society for the Advancements in Kinanthropometry, and the American College of Sports Medicine, from which he was granted Fellow member status in 2010.

A journey through my years of PhUn: lessons learned

PhUn Week is very dear to me as it has been an important part of my professional life for the past 15 years. I was fortunate to be elected to serve on the APS Education Committee in the early 2000’s.  At that time, APS, and specifically that committee, were interested in increasing member outreach and I was charged with the task to develop an outreach program.  There were other professional societies that promoted “awareness days” to increase their visibility to the public and it was thought that we should attempt to do something similar.  After playing around with various acronyms, I pitched Physiology Understanding or “PhUn” Week to the committee.  My thinking was that very few lay people I spoke with about my career knew what a physiologist was or did, so I thought increasing public understanding of the importance of physiology and physiology research would be a laudable goal and, in doing so, we could show people just how “PhUn” physiology can be!

According to my records, PhUn Week was officially rolled out by APS in 2005 and I have run a PhUn Week event every year since then, having just completed my 13th event this past November.  Over the years I have visited elementary, middle, and high schools.  These schools have been in affluent suburban, middle-class urban, and high-poverty urban schools.  I have done activities with a small class of about 20 and with groups as large as 100 students at a time.  We have covered a wide range of topics, from cardiovascular adaptations to exercise and extreme cold, to DNA and transgenic animal models of disease. One of the things I love about PhUn Week is the ability to share the wonder of physiology with students of all ages and backgrounds and see the excitement in their eyes when they “get it”.

Looking back on the common denominators of my wide variety of experiences with this over the years and the ability to fit a PhUn Week visit into my busy professional life each November, successful PhUn Week participation seems to have come down to three important factors.

#1: Find an effective school partner

My first experience running a PhUn event was at my daughter’s middle school in 2005.  The 8th grade science department chair was extremely interested in providing new experiences for the students, so she was an easy sell when I approached her with this idea.  However, she was adamant that whatever I planned needed to be for all the 8th grade students, and not just selected students, such as the “gifted and talented” group.  I completely agreed with her on that point as I am more interested in reaching the students who don’t think they like science or who don’t think that they “can do” science than working the whiz kids who already get it.  The problem with that though was that I needed to present to a total of 300 students.  We handled the situation by having 3 consecutive 1-hour sessions to 100 students in each session and used the school gym so that the students could spread out and do an activity on cardiovascular adaptation to exercise.   It was a whirlwind but we made it work!  The whole process was made so much easier by having a motivated school partner who came up with solutions to potential problems and was able to make the facility arrangements necessary to have a successful event.

Finding that school partner who is motivated to have you visit and is willing to do necessary shuffling of classes and room scheduling is extremely helpful. I have been lucky over the years to either have connections through my children’s schools or through colleagues.  If you don’t have that luxury, try e-mailing science teachers from websites of local schools.  Teachers will self-select by either replying if they are extremely motivated to assist you or not replying if they are not interested.  One you find a great school partner, the rest is easy!

#2: Connect to the curriculum

Learning always works best by building upon an existing knowledge framework rather than starting from ground zero. In 2006, my daughter was now an 8th grader at the middle school so I had already made the connection with the department chair and now I was aware of much of the science curriculum.  That fall, the class had taken a field trip to a biotech company and learned how to transform bacteria so that they fluoresced in different colors.  I had been a chaperone on the trip so I could see how it was presented to the students and how they were led through the activity.  Were they successful in producing bacteria that glowed different colors?  Yes, they were.  Did they think it was cool?  Yes, they did!  Did they have any clue as to what they were doing or the significance of it?  None whatsoever!  As I was considering what to do for the PhUn Week visit that was coming up, I suggested that I might try to connect to that experience by digging a bit deeper with them and exploring what DNA was, connecting DNA to proteins and their multiple functions and ultimately to physiology!  Back in those days, researchers in our department had recently been the first to develop a transgenic rat that expressed green fluorescent protein and thus glowed bright green.  I connected the glowing bacteria that they had produced with the glowing rats the researchers had produced by working through the science behind both experiments.  In the case of the transgenic rats, however, we were able to discuss the important potential of this new technology to biomedical research.  Close connection to the curriculum is not required but it is helpful and gives what they are learning in school real-world relevance.

#3: Have PhUn!

The most important lesson I have learned over the years is to just have PhUn with it! The students are more engaged when you show them how excited you are about the subject.  My daughter, who was an 8th grader during my 2nd PhUn Week event back in 2006, is now a 3rd grade teacher at a high-poverty inner-city school.  This past fall I visited her classroom for PhUn Week, which is the earliest grade level I had visited to date so I was a bit nervous about hitting the correct level.  I got some ideas from the PhUn week activity book about “Phreezy Bear” and decided to focus on adaptations to cold in polar bears and in humans.  My daughter prepped them for the visit by reading them a picture book on polar bears the week prior so they were able to begin the visit by teaching me about how polar bears   stay warm.  They then tested the effectiveness of these adaptations by wearing fur coats to protect them from the arctic wind (me fanning them), placing their hands in ice water with or without Crisco-lined baggies to demonstrate the insulation blubber provides, and measuring water temperature in small glasses wrapped in white or black paper and set in the sun for an hour showing that the black skin of polar bears absorbs more heat than light skin.  We wrapped it up by discussing the different mechanisms that humans have that protect them from cold.  Through it all, the students and I had great PhUn playing with the activities and learning through exploration!

Equally as important as having PhUn on the day of the event is making the entire preparation process PhUn, because if it is something you are dreading doing, you will be less likely to make time for it. What one considers PhUn will be unique to each APS member so I won’t presume to dictate what that might be for you.  For me, I enjoy not having to reinvent the wheel each year because that it too time-consuming.  I like to take what I have done before and build from that.  At the same time, I would get bored doing exactly the same thing each year so I take what I did and tweak it to keep it PhUn for me.  Some years I tweak it more than others.  It varies depending on whether I’m going to the same school and grade level as the previous year or whether that is changing drastically.  It also depends on how crazy my work schedule is each year as to whether I do something tried and true or take some time to tackle a new idea.  Basically, the ability to conform the experience to my abilities and interest each year is what keeps it really PhUn for me!

Finally, why do I really keep doing this each year? I am a firm believer in the power of scientific exploration with children at an early age and that these experiences are long-lasting.  Long before PhUn existed, I visited my daughter’s kindergarten class and explored lung function with them.  At their 5th grade graduation ceremony, each student in her class had to go to the microphone and say what their best memory of elementary school was.  One boy said that he remembered when Dr. Munzenmaier came to his class 5 years earlier and taught them about lungs and that now he wants to be a doctor. We don’t need every child to go on to have a career in science, but we do need every child and future citizen to appreciate the importance of science in their life and in their world.  I believe that we, as APS members, have the ability, and the responsibility, to do just that.

  Diane H. Munzenmaier, PhD currently serves as Program Director at the Milwaukee School of Engineering in the Center for BioMolecular Modeling, specializing in the development of educational programs and resources, as well as professional development for middle school, high school, and college level bioscience teachers.  Diane was previously a faculty member in the Department of Physiology and the Human & Molecular Genetics Center at the Medical College of Wisconsin.
Mississippi Museum Madness

We were first introduced to PhUn Week about a decade ago through our service to the APS Education (Mike) and Trainee Advisory (Jenny) Committees.  We both began our involvement with this annual event by visiting our children’s schools in Mississippi and Florida, but in 2013, we combined efforts with other faculty, fellow, students and staff at the University of Mississippi Medical Center (UMMC) to bring PhUn Week to a larger audience at the Mississippi Children’s Museum.  Through this event every year, we reach over 300 children and parents, and we have over 40 volunteers who spend their Saturday operating 9 different stations.

In addition to being an outreach event for the Jackson, MS community, this PhUn Week event also provides professional-skill-building and team-building opportunities for our students and fellows. Although the first time we held this event at the museum, it required a lot of planning and preparation by faculty, now the event is almost completely run by fellows and students from the Departments of Physiology and Pharmacology.  We have also worked with the UMMC School of Graduate Studies that provides additional support for our event.  Eight team leaders are responsible for recruiting a team of volunteers, training those volunteers on the activity for that station, and making sure all of the supplies are ready and within the budget for the event.  Team leaders are responsible for setting up meetings before the event to discuss best practices for running the station and for ways to engage the children in the activities.  This is a great way for students, fellows, and faculty to learn to talk about science with the public – sometimes the parents have more questions than their children!

The event was divided into 9 stations with 4 organ system based themes.

  1. Welcome Station / Bag Pick Up
  2. Gut Gallery
    1. Antacids and Stomach Acid
    2. Make Poop
  3. Heart Haven
    1. Hold a real heart
    2. Test your heart rate
  4. Kidney Korner
    1. Hold a real kidney
    2. A microscopic view of the kidney
  5. Lung Lounge
    1. Learn about the lung
    2. Test your lung Volume

 

At the welcome station, volunteers greeted museum patrons to encourage them to visit the special PhUn week event.  Each participant received an activity card and earned “check marks” for every station they visited to help them keep track of which stations they had completed.   When the children were done touring the stations, they returned to the welcome table to receive their PhUn week goodie bags.

 

At the “Gut Gallery,” children learned about the digestion process by making “poop.” Each child got pumpernickel bread to tear apart (action of the teeth) to squeeze down the neck of a balloon (the esophagus) with some help from soapy water (saliva).  Once the bread was in the body of the balloon (the stomach), the children added vinegar (stomach acid) and began to churn the mixture.  The children then inverted the balloon so that the neck of the balloon became the intestines / colon, and then squeezed out the “poop.”   The kids give a big smile or a loud “GROSS!!” after that!

 

At the next station, the children explored how over-the-counter antacids can neutralize stomach acid.  We used Sprite as our “safe for children” acid, and we let the children pipette Sprite and red cabbage dye (pH indicator) into 4 plastic test tubes.  Then, they mixed in Tums, Alka Seltzer, Milk of Magnesia, or baking soda to observe the color change as the solution became more basic.  Note – milk of magnesia usually has the biggest pH shift – but the Alka Seltzer is fun when it bubbles!!

 

The “Heart Haven” station was focused on learning about the structure of the heart through real fixed hearts, plastic models, and computer animations.  Participants were able to examine formalin fixed hearts taken from vertebrate animals at the time of sacrifice (canine, ovine).  The fixed hearts (stored in ethanol) were rinsed in water for 1 week in order to avoid any problems with touching alcohol. The hearts were hemisected prior to the visit so that the students could easily examine the chambers, valves and major blood vessels of heart.

Then, the children examined how going from resting to doing jumping jacks could change their heart rate using Vernier Physiological Monitoring Systems to measure heart rate.   The children plotted their data on a graph (x-axis: resting or exercising, y-axis: heart rate) to visually show the impact of activity on heart rate.

 

 

At the “Kidney Korner” station, we again provided plastic models and formalin fixed kidneys (canine, ovine) so that the children could learn about the structure and function of the kidneys.  The kidneys were hemisected prior to the visit so that the students could easily examine the renal cortex, medulla and papilla. The volunteers explained the basic anatomy of the kidneys and how each organ is made from individual, specialized cells, and then the children viewed histological sections from normal kidneys and diseased kidneys (glomerulosclerosis, diabetic kidney disease, fibrosis).

 

 

One of the most popular stations for children and their parents is the “Lung Lounge.” Children learned about lung structure and function using plastic models and computer animations, and they got to see real fixed human lungs from a smoker, a patient with emphysema, and a healthy patient.  The children were quick to note how bad smoking is!  The children then got to measure their lung volume (and sometimes challenge their siblings or parents to a contest) using basic household items like milk cartons and straws. Pre-marked gallon containers were filled with water and turned upside down in a water filled bucket.  Using a bendable straw inserted into the opening of the gallon container, children were instructed to inhale maximally and then exhale maximally into the straw.  The exhaled breath displaces water in the gallon jug to allow for measurement of lung capacity. The children then plotted their lung volume as a function of age to see how lungs grow with age.

 

 

If you’re attending the Experimental Biology conference, come visit us at the Sunday morning poster session (7:00 AM) to talk with APS members who have been involved in various PhUn Week activities.  It is a great way to get more ideas and learn what works and what doesn’t as you get ready to plan your next event!

Diary of an Adventure Junkie: Part Trois…Try Something That Frightens You…It Could Turn Out to be PhUn

Are you a kid person? I am a self-proclaimed kid person, but I haven’t always felt that way. Kids are amazing sponges…seeking knowledge, attention and guidance, but they are also loud, challenging, sometimes germy, balls of energy.

I started out being a non-kid person when I was a kid myself. I primarily surrounded myself with adults, not always by choice, but certainly a circumstantial hazard of being an only child who moved frequently (13 times in 11 years). While I was encouraged to invite friends over and did, I preferred one-on-one time to massive playground free-for-alls. After settling in one place, and becoming a sullen teenager, kids weren’t really an issue, as I lacked siblings and fervently avoided friends’ sticky-handed brothers and sisters who insisted on following us around. By college it was official; I was absolutely not having any kids of my own. I barreled down my educational path determined to achieve great feats by extremely young milestones. So far, so good…


Do you remember the game of life…roll the dice, move your car, and then suddenly you are going to the chapel and your peg (pink in my case) is joined by another peg (blue in this story) and then more pegs…Eek! Now is the time to swerve to the side of the road and reevaluate where I went off course, or did I?

Let’s do a quick self-assessment: 

PhD earned –            

Found a nice boy and visited the chapel –            

Postdoc acquired –           

New pink peg in the backseat –              

WHAT?!?!   Where did the path diverge? At what point along the way did miniature pink pegs enter the picture? Where did my comfort zone go?

 

Okay deep breaths…

I can do this. I like adventures.  I can do this!

 

 

“I can do this” became my daily mantra and guess what…I discovered that I could do this. Not only could I do it, against all odds, I liked it. I was a kid person, well at least a kid person where my kid was concerned.

I still had reservations about other children. After all, they weren’t mine. I tolerated them, went to playdates, talked about “mom things” with acquaintances, but I didn’t really understand. I marveled at mothers who had more than one child, questioned the sanity of those who regularly hosted sleepovers, and stood in awe of preschool teachers who welcomed our offspring into their classrooms every day.

And then one day it happened…

A trusted colleague and friend suggested that we should participate in PhUn week. What is that I asked? I hadn’t even heard of PhUn week, much less knew what it entailed. When I discovered that I could design an activity to teach students physiology I signed up immediately because creating a new physiology demonstration was, after all, fun and exciting. And who wouldn’t love PHYSIOLOGY for kids?!?!

 

The day arrived and although I had prepared meticulously for my portion of the event, nervousness overtook me. Suddenly it was my turn to speak and the 50 pairs of fifth-grade eyes staring at me seemed to bore into my brain asking me, “Do you like teaching us? What are we going to do? What if we all decide not to raise our hands?” I drew in one more deep breath…

 

“Who knows how oxygen travels through your body?”

 

Several hands shot into the air and I knew I was going to be okay. My first participation in PhUn week was a huge success. The students enjoyed it, learned a lot about oxygen transport, we shared our day with colleagues during the PhUn week poster session at EB and published our poster in the LifeSciTRC.

I was hooked! I began planning the next PhUn week activity just a few, short months after my first event.  This time we would include elementary students and preschoolers. I decided to invite 60 fourth grade students to the medical school for a full day of events covering multiple organ systems and branching into other disciplines such as art.  An event at my daughter’s preschool was also on the agenda, teaching 3 and 4-year-olds to listen to heartbeats.  But wait…I don’t like kids…at least I didn’t like them…hmmmm, maybe they were growing on me.

With each new event, it became clearer that I was becoming a kid person and kids were now well within my comfort zone. I no longer felt annoyed with all of the questions; I welcomed the opportunity to share science and relished each hug from appreciative students.  I began hanging crayon-covered thank you cards up in my office, next to research awards and physiology textbooks.  I smiled each time a child stopped me in the hall to tell me about a “more often” food choice they had made instead of a “less often” food choice (one of our lessons included guidance on choosing fruits and vegetables and other healthy choices more often than candy, chips, and coke). I soon found myself looking for outreach opportunities outside of PhUn week and volunteering to teach others about organizing and carrying out community involvement events.  I beamed with pride when I realized that 2017 was my seventh year to participate in PhUn week. Kids no longer frightened me; in fact they excited me, particularly when I shared science with them. I had truly become a kid person.

In September, I asked my daughter, now a third grader (NRTP), if she wanted me to come to her classroom again and lead a PhUn week activity.

“Of course,” she said without hesitation. The conversation that followed went something like this…

 

Me: “What system should we do this year?  I realize that you are probably tired of the cardiovascular system.” (Please note that this is the primary system in which I trained and of course my favorite, hence the subjugation of my daughter to it year after year.)

 

NRTP: “Poop!”

 

Me: “Excuse me, poop is not a system.”

 

NRTP: “Poop!”

 

Me: “You want to study the GI system?”

 

NRTP: “Yes, as long as we make poop!”

 

Oh no! What had I gotten myself into? Digestion, stomach acid, liver enzymes, bile, and of course, poop…no thank you! Have I mentioned that the GI system is my least favorite? Here comes another adventure far outside the comfort zone. Following many hours of plotting and planning, diligent searching in the LifeSciTRC, and a couple of phone calls to a colleague (big sigh), it was settled, a plan emerged and GI physiology was on the horizon. I would lead a three-part session complete with an experiment, a video and a demonstration. We would even make “poop;” well, digested cracker, but it was close enough.

 

The day arrived and first PhUn week jitters resurfaced. I didn’t know this classroom, these children, or this system, but I stood determinedly in front of the room. I was pleasantly surprised at the students’ description of a scientist, intrigued by their questions, and excited to share physiology with them. The GI system was suddenly thrown into an entirely different light. Once again kids demonstrated to me that life is better when shared with them.  How else could my least favorite physiological system suddenly seem so amazing?

 

As I reflect on engagement in outreach opportunities throughout my career, I appreciate that outreach not only opened my eyes to personal change, but also professional paths. After carving a few notches in my PhUn week belt, I was named outreach coordinator for the medical school where I was faculty, given an operational budget for my activities and asked to serve as founding director of a health careers camp for inner city kids.  Professionally, becoming a kid person partially shaped my career and led to new forms of career development.  Teaching science to elementary age students encouraged me to rethink my examples and explanations in the medical physiology classroom.  It also spurred me to engage the students through more media and hands-on activities, ultimately leading to greater student success with understanding the most challenging physiological concepts.

 

So, what does it all mean?

  • Change is inevitable.
  • Change can be life-altering, but even when it isn’t, it’s a learning experience.
  • Any change can be an adventure if you are willing and open to the possibilities.
  • Change can start as personal and end as professional and vice versa.
  • In many cases the teacher is actually the student.
  • Sometimes the unwanted, or seemingly unwanted, adventures are the greatest.

 

So, I challenge you…go on an adventure, step outside your comfort zone and choose the divergent path because you never know where it might lead.
