Balloon Chemical Change Experiment, Chemical Change Lab:
In this chemical change lab, students will observe how baking soda and vinegar react in a plastic bottle to blow up a balloon and produce a chemical change. Teachers will need to provide vinegar, baking soda, a balloon, and an empty water bottle. I usually have one set up per lab group.
My students always have a "Wow!" reaction to this experiment. It's such a fun and informative way to "see" a chemical change.
Included in the page is a gentle introduction to chemical formulas.
