Working with Polymers – TVHS ChemClub Outreach Activities


On October 21, Tanque Verde High School ChemClub  visited twoTVHS_9 elementary schools in our school district.  We presented a series of hands-on science activities, related to the chemistry of polymers, to the 3rd graders (approximately 175 students).  In order to visit both schools in one day, we divided into seven teams of 3-4 people.  It took us several days to get ready for the event. We practiced the experiments we were going to perform with the students over the past two weeks, rehearsing what we were going to say, and preparing our materials.

Laden with boxes of supplies, goggles for the students, and bottles of distilled water, we have arrived at the elementary schools early Monday morning.  Some club members were nervous and apprehensive about the presentations,  but once we  started, everything went well.  After a short set-up and distribution of materials we have launched into the activities.


TVHS_5Our activity was based on the ACS kit “Jiggle-jells”.   The opening demonstration (an attention grabber) was very well received and got the kids interested in what was to come next. We added a demonstration on making “instant snow” (here in Arizona snow is special!) We also added a graphing component to the part where students made a small, dinosaur-shaped toy that expands in water. The elementary school students were thrilled by all of the activities and eager to do them.

The best part of the event was seeing kids’ faces while we were doing the labs. We saw kids  alternately awestruck or grossed out, or just dumbfounded by what they were observing.  Such as when they made slime and were able to play with it.   Our ChemClub students found it rewarding to teach the kids and see them responding to the instruction.   Knowing that some of the skills these students learned during our session will stay with them in the future was very satisfying.  It was great to see that we were role models in the students eyes, and that they looked up to us.

And of course, the kids made a number of memorable comments, all delivered with a huge grin:

  • “You guys are letting us do a bunch of fun experiments today!”
  • “I want to be a scientist now!”
  • “I thought science was supposed to be boring. This is fun!”

What has impressed us? Many kids had amazingly insightful ideas on TVHS_1how these polymers worked. One of the girls gave a detailed description of the dinosaur experiment,  showing off her knowledge of the topic.  It was also great to see  the 3rd grade teachers were just as interested in the experiments as their students, and asked additional questions about the polymers and how the experiments were prepared.

Our club learned how to plan an effective presentation and how to work with small kids. We found it was  hard to make sure  the students understood the instructions.   We found it takes a lot of patience to work with younger students.  Although some things could have been explained better, perhaps using different examples, over all, we felt we did a good job.  We hope that other high schools get a chance to participate in the event like this one, and we would love to do it again!  It was incredibly rewarding experience for all of us.  It is one thing to learn, but another thing to teach!
