Week 7: Fun Discoveries and a Foam Fight

May 17, 2022

Welcome back to my blog! 

This week I did the elephant toothpaste reaction with my Remington students. It was super fun! Students were very enthralled by the visual reaction. I primarily worked with elementary school students and a few middle schoolers for this session. 

For the elephant toothpaste reaction, I had students combine hydrogen peroxide and dishwashing liquid with yeast. This produced a fast-reacting foam that spilled over the plastic bottles we did the reaction in. Students were so excited that they even started a mini-foam fight with each other. Luckily I did not get hit in the crossfire! I was able to explain the properties of yeast using this reaction and how the combination of activated yeast, hydrogen peroxide, and dishwashing liquid produced this foamy substance.

Over the past few weeks, I have struggled a little bit to relate some experiments to environmental science and climate change. I have mainly been aiming to just get students invested and interested in science, for they have not had much exposure to it. Furthermore, I have sacrificed the environmental part of my program a little bit and have tried to focus more on creating fun and visual reactions. The environmental science part of my program will become more prominent soon, but I first have to establish a passion for science in my students. That is the time challenge of the senior project, though, as I only have a few months to execute my program. In a perfect world, this program might run 6-8 months, but I have tried to condense it for the senior project time period. 

My students are becoming more and more passionate about science and STEM, and I look forward to also teaching them more about environmental science and climate change. Next week we will be doing bottle rockets. I will report back on how that goes!

    The elephant toothpaste experiment sounds super fun! Makes a lot of sense that some of these experiments don’t fully relate to the enviornment/climate. Perhaps you could sneak an enviornmental science lesson in on recycling/reusing when you mention bottles 🙂
