The first group of kids just left the building, and I wait patiently for the next group of second and third graders to enter. It’s a chance to think, a chance to reflect on what I’ve attempted to teach and how the kids reacted. I oftentimes wonder if anything that I say is transferred, if any of the students understand.
Maybe I could have worded that better.
This thought always races through my head, as I’m constantly looking for a better way to teach to reach more kids. I change my wording this time. Better?
In Fall 2014, Tanque Verde High School ChemClub members had an opportunity to work with 3rd grade students in our school district presenting activities about polymers provided by the American Chemical Society. We were assigned to a specific 3rd grade teacher at two elementary schools in Tucson, Ariz. (Aqua Caliente Elementary School and Tanque Verde Elementary School). For some of our veteran ChemClub members it was a second chance to work with elementary school kids.
It took us two weeks to build kits for the students to use during the outreach, as well as to practice our presentation. Most of the ideas were from the “Jiggle Gels” guide, but we included an activity to illustrate cross-linking and expanded the demo to show the making of artificial snow.
Everyone was expecting us at the elementary schools. Kids were very excited seeing us with the boxes full of materials and could not wait for us to start. In all of the excitement, lots of water got spilled on the tables. Luckily we were prepared and brought additional supplies with us!
Sodium Polyacrylate Polymer
Kids were completely stunned by the first demonstration where the water poured into a series of cups seemed to disappear when the cups were inverted. The students were even more interested in this demo when we showed them how properties of sodium polyacrylate polymer made this possible. It was a very good opening to the outreach presentation because this demo caught the students’ attention and made them want to experiment with that substance.
They really liked working with pipets and studying the properties of the sodium polyacrylate polymer.
For our next demo, we made artificial snow. That was a big hit! Everyone was fascinated with it, many saying things like “Wow! It even feels cold and wet like snow” and one student even tried to make off with a handful of the snow before we caught him.
Distributing the Gro-Dinosaurs for a graphing activity was a good break for the kids because they could remove their goggles for a while. But no one complained when we told them to put the goggles back on. They were so excited to make slime!
For the Super Slime activity most of students handled the pipet and borax solutions very well and had no trouble deciding quickly who would stir and who would add the solution. They loved the slime they had created and we could barely get some of them to divide it and store it in plastic bags so they could take it home later.
To help 3rd graders to understand how slime is made, we had a cross-linking activity. We had volunteers to wear green tags with “X-link” written on them. All other students made chains by holding hands, and the kids with the cross-link tags were grabbing to the chains.
Water, Pencils and a Plastic Bag
During the final demo we compared two plastic bags made of different polymers. Kids couldn’t believe that the PVA plastic was dissolving in water. Then we put water into a regular plastic bag to show them that it had different properties. We did this by poking sharp pencils into the bag, but this plastic is so elastic the holes made by the pencils didn’t leak. I had to refrain from laughing when almost every single kid flinched as the presenter stabbed the first pencil through the water filled bag. To be completely honest, I was actually silently praying that the bag wouldn’t rip and spill all over the floor. By the looks of him, the student presenting this was thinking the same thing.
Our students reacted enthusiastically to every part of our presentation, and their comments were the best part of the day. We kept the students engaged with jokes and hands-on demonstrations, both of which they loved. One student cheered “You guys are the most awesome people! You do all the cool stuff!” and another proclaimed “I love chemistry!” I am particularly fond of the second comment, because the girl and many of her peers were taking a genuine interest in chemistry. When we asked “Do you guys want to know how slime works?” the class shouted their approval. The participation was amazing. Whenever we asked a question, nearly everyone raised his or her hand with a grin and enthusiastic expressions. Even as their eagerness peaked, they remained respectful and followed our directions. We kept things interesting, and they did not dare turn away from us because they truly wanted to do more, and know more about what they were doing. Even beyond that, they wanted us to come back because they wanted to know even more about chemistry and what we could do with it.
My favorite part of this activity was working with the students and being able to see their reactions. One student even asked me an in-depth question about the workings of chemistry, which was very exciting to see in someone so young. I loved being able to see how enthusiastic these young students were about learning about chemistry.
During the cleanup, one of the boys walked up to me and asked “Are you going to be here every day?” I was caught off guard and had to ask “Do you mean for the rest of the year?” He nodded eagerly and I, myself, was disappointed to tell him we weren’t. After he sat at his desk a girl came up to me and said “I hope you come back next year! This is really fun.” I couldn’t help but grin and assured her that we’d be back.
I have discovered that third-graders can be surprising in what they do and do not know, so presenters should be prepared for both insights and unexpected questions. I’ve had a great time and could see the enjoyment in the kids. I hope that one day, they follow with the foundations we laid for them and join the ChemClub themselves!
SciFest was held at Illinois Valley Community College (IVCC) on Friday, April 11.
SciFest is an annual celebration of science put together by IVCC professor Matthew Johll. Instead of people gathering in a gym to watch a sports contest, at SciFest they came together for hands-on science experiments and demonstrations designed to help them understand how science work in everyday life. This year some 500 people attended.
The Ottawa Township High School ChemClub was there also, to lend a hand in presenting some of the activies. We had about a dozen members of our club attend and present the following hands on demos:
Dr. Johll laid on the bed of nails and had the cinder block broken on his chest. Some IVCC students demonstrated a flame tube (also known as a Rubens’ Tube) that showed the acoustic waves in the flames as a guitar was played, and the crushing of the 55 gallon drum by air pressure.
In addition any Cub Scout could earn their Science belt loop or Boy Scouts could work on a Chemistry merit badge at the event.
In the end, the event generated a lot of excitement and thinking about science, and again, unlike a sporting event, there were no losers and everyone won.
Want to submit an application for a ChemClub Community Activity Grant before June 1, but don’t have a project idea? Or, is your Club simply looking for something new to try? Why not turn STEM into STEAM? Fusion Science Theater (FST) takes Science, Technology, Engineering, and Mathematics education to a new creative level by adding the Arts. The Fusion Science Theater website describes FST as a STEAM outreach program that uses the secrets of theater to create outreach shows that actively engage children in learning science. They’re short, interactive shows that weave demonstrations together with predictions, modeling, and a storyline, targeted for an audience of grades 1 through 5.
How can you bring this program to your area? Apply for a Community Activity Grant to purchase a FST show performance kit! The kit will give your Club everything they need to perform the show in your community. The kits include a show script, video of a live performance of the show, list of materials and props you’ll need, a handbook for training and performance tips, and even instructions on how to assess learning achieved during the show.
If I Were an Atom to explore kinetic molecular theory and how atoms move in the solid phase. Watch a video preview.
Bouncemania! with a “Wrestlemania”-style match between happy & sad toy balls to learn about polymers and molecular structure. Who will be crowned “The World’s Bounciest Ball”? Watch a video preview.
Will It Light? to test and model the flow of electricity through different substances, as students investigate conductivity. Watch a video preview.
FST shows are more than just sharing your typical demos. They are inquiry-based. Show characters lead students to investigate a question that motivates the audience to learn a basic chemical concept. The shows are highly interactive. Audience members get to assist on stage, vote for their prediction of what will happen in a demonstration, and more. It’s easy to measure the impact and learning using assessment info included in the kit. The theater techniques and elements used are a great way to keep your audience’s attention.

On November 22nd, after two days of no sleep, plenty of bagels, and a few too many juiceboxes, we presented eight episodes of the Lakeville South High School Spectacular Science show. During the school day we presented to all 1,855 students in our school, followed by our 6:30pm grand finale in front of the Lakeville Community, Lakeville, Minn. Before the sun set, we had displayed the incredible power of chemistry to over 2,700 Lakevillians of all ages.
We began each show with a grand welcome: “Hello and welcome to Lakeville South’s Science Show 2013! Tonight I will be your MC….that is MC△T. During the next two hours, we will guide you through Moley Potter’s Chemistry Quest. Our lineup for tonight includes the Hydrogen Rocket, Vortex Cannon, Boo Bubbles, Flying Fish, Flaming Snowballs, Grain Elevator and much more. See before your eyes 140 film canisters shoot in the air, 20 balloons explode into fire, and a 50 gallon barrel implode with a few squirts of water…and let’s hope the electric pickle actually works! Put on your seatbelts and prepare to take a ride with us through pops, sizzles, crashes, and well…chemistry!”
We are the AP Chemistry students (and ACS ChemClub members!) at Lakeville South High School. We performed 33 experiments in the amazing, the magnificent, the life-altering Lakeville South Science Show (a.k.a. Chem Demo Day). Over the course of five November days we planned and perfected the most amazing display of chemistry the world has ever seen, with a Harry Potter twist.”
Audience member Maddie (a 6th grader) said after the show, “It was way cooler than I expected. It really makes me excited to take chemistry in high school.” Lisa King, AP English teacher at LSHS commented, “I thought Chem Demo was great. I brought my 6th grade daughter for the second year in a row. She asked if she could bring a friend this year because it was so great the year before. I think that it does a lot to show younger kids how ‘cool’ science is and how many older kids are interested in it. The weekend after the show, she and the friend figured out how to make “monster toothpaste” and made several batches.”
It wasn’t only spectators that enjoyed the Science Show. Current AP Chemistry
student (and talent behind Boo Bubbles), Annika Tureson, explained, “The demo was definitely the best thing we’ve done in AP Chem. It was super fun to do hands-on experiments and teach others about chemistry.”
The 2013 Chem Demo went down in the books as a huge success…definitely thermodynamically favored. It is undoubtedly an experience we will never forget. Although a few presenters took away some scrapes and bruises, and one slightly singed shirt, no one will ever forget the message…Chemistry for Life.
