Baggie Bombs

Supplies

1. 1 Tbs. baking soda
2. Zip Lock bag
3. Dixie cup full of vinegar

Concept: Chemical Reactions- Baking soda and vinegar make a gas (carbon dioxide) and heat was absorbed (it gets cold).

Procedure: Have students place 1 Tbs.of baking soda in Zip Lock bag, pour Dixie cup of vinegar into bag and zip tightly.

Extension: Use yeast instead of baking soda and hydrogen peroxide instead of vinegar to make a different gas (oxygen). This experiment will produce heat.

Application to Real World: We breath in oxygen and exhale carbon dioxide, while trees absorb carbon dioxide and release oxygen out into the environment.
