Today we did an experiment from Bill Nye’s “Big Blast of Science.” On page 18, there's a chemical reaction experiment that many of you have probably done in one form or another over the years. This one is called the CO2 Balloon. The interesting thing about this mixing of baking soda and vinegar was that we were able to feel the heat produced by the chemical reaction, which Bill tells us is a form of energy. :)
"Energy can be stored or released by a chemical reaction. That's why chemical reactions are so important: they not only produce new chemicals, they produce (or take away) energy. When a car burns gasoline to make the car go--that's a chemical reaction. When your body converts breakfast into energy for skateboarding--you use a lot of chemical reactcions. We can't live without them."
And I'll be darned if I couldn't feel a slight bit of warmth in the balloon when we did this.
Thomas tried it in a water gun as well, but it didn’t really do anything. LOL Baking soda and vinegar are always exciting, though, you never know what'll happen!
This looks interesting, from WikiHow, but we haven't tried it yet--How to Make a Baking Soda and Vinegar Rocket. Now this one looks really to be up Thomas's alley! How to Measure Thermal Energy Released from a Flame
I thought I'd mention a couple other books from Bill Nye:
- Bill Nye the Science Guy's Great Big Book of Tiny Germs
- Bill Nye the Science Guy's Consider the Following
And he's got his own website, of course. We've been checking out his DVD's from the library recently. There are a lot!
