This week would have been the last of the unit on fire. We would have ended it by making a volcano. You could do it yourself! Use an apple and material that’s easily available at home.
When you combine baking soda and vinegar a chemical reaction occurs that releases carbon dioxide. The baking soda (sodium bicarbonate) is a base while the vinegar (acetic acid) is an acid. When they react together they form carbonic acid, which breaks apart into water and carbon dioxide, and creates fizzing as it escapes.
-Dish or container to catch the fizz
-Knife to cut center from apple
1. Prep your apples by cutting a hole in the top of each apple. (Dad completed this step.)
2. Put equal amount of baking soda in each apple.
3. Pour vinegar into each apple and watch it fizz.
4. Draw your conclusions
