Today we did a bunch of experiments involving both chemical and physical changes. Since the chemical changes are more fun, those are what I took pictures of!
We combined vinegar and baking soda to create carbon dioxide gas bubbles!
We used a solution of vinegar and salt to clean old, dirty pennies and make them shiny again! The pictures of this one aren't as impressive, but the kids were still amazed at the result!
For the grand finale, we used the same combination of vinegar and baking soda to create carbon dioxide gas to blow up a balloon with air! Check out the awesome expressions on the kids' faces.
And my favorite picture of the day!
Tomorrow, we're going to create some chemical and physical changes involving fire! Then, Friday we're going to do a bunch more WAY COOL experiments with carbon dioxide gas! And next week is SLIME LAB - A whole week of making all kinds of slimes, goos, and other concoctions!
