Good afternoon scientists! We just got done doing another super fun chemistry experiment. You will definitely want to check this out with your little scientist.
Gloves (We used Nitrile)
Measuring Cup (2)
1/4 Dry Measuring Cup
Instant Yeast (1 packet, we used rapid rise)
Hydrogen Peroxide (It is an antiseptic usually by the band-aids)
Vase or Cup (One with a narrow top works well)
Optional: Apron (If worried about staining your clothes.)
Recommended: Paper Towels to help clean-up or a disposable pan to place under the vase.
**Never eat or drink in lab setting. Watch your child at all times. Do not ingest. Wear your safety goggles and gloves for this experiment**
**This is a messy experiment. Best done outside, where you can hose it off after or place a disposable pan under the vase**
- In one measuring cup combine 1/2 cup of warm water with one packet of yeast. Mix together well.
When the yeast combines with the hydrogen peroxide and soap mixture it causes it to foam up. The foam is the result of a chemical reaction or chemical change (a change that can not be undone). If you try touching the foam it will be warm/hot. When the chemical reaction occurs one of the byproducts is heat or thermal energy.
