Learn about the effect a catalyst has on a chemical reaction.

• Students will visualize the decomposition of hydrogen peroxide - as the reaction occurs, a large amount of foam is formed that flows up and out of the reaction bottle.
• Aligned to NGSS Practices
• Performance expectations: 2-PS1-4, 2-PS1-3, 5-PS1-1, 5-PS1-4
• Disciplinary core ideas: PS1.A, PS1.B
• Cross cutting concepts include cause and effect, energy and matter, scale proportion and quantity

This activity is a fun, safe way to teach students the effect a catalyst has on a chemical reaction. The decomposition of hydrogen peroxide can be visualized by mixing in a small amount of dish soap and adding yeast as a catalyst. As the reaction occurs, a large amount of foam is formed that flows up and out of the reaction bottle. This kit contains an Instruction Manual and enough materials to perform the demonstration twice.
