Pop Rocks and CO2 – Who Knew?!

I have told the girls that Science can be applied to anything. So today I started our session a little differently. We learned self defense! How to know our bodies better in the ability to deflect objects. I taught them about our bodies center of gravity. Where we get our energy from and how it’s different amounts of energy we use depending on our body positions. Since we started talking about our bodies I asked all the girls to breathe deeply in and out. I explained to the girls as they were inhaling and exhaling, their bodies use the oxygen and create CO2 and that is what comes out when we exhale. With that being said let’s play with candy!

Do you know the scientific method?

Our main activity was the pop rocks and soda experiment. Where we use the combination and see how it can blow up balloons. Pop rocks are great candy that has CO2 in them which helps in adding soda so there is more produced in order to inflate a balloon. Donya, Caremah, and Sarah were my go to helpers today. Donya helped take pictures of us and the girls putting the experiment together. Caremah was my first volunteer to help me putting the materials together even though all of the girls happily participated. Sarah was our note taker. Sarah followed each step and noted down our scientific method and what we thought was going to happen. Donya really stepped it up today and even gave the right conclusion on why Pepsi inflated the balloon the most. I could see that she was more confident in this particular experiment. The girls had a really great time and was more excited when awarded pop rocks for doing such a great job today 🙂

Who knew PopRocks could be fun and educational?!
