Get a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases an oxygen atom from the hydrogen peroxide, resulting in a foam that shoots out from the bottle like toothpaste.

Instructional Ideas

• Take the class outside to conduct the experiment so cleanup isn't a problem
  

Classroom Considerations

• Requires a variety of materials, including 3% hydrogen peroxide, dish soap, and dry yeast
• Basic knowledge of atoms and molecules, as well as chemical reactions, is beneficial
  

Pros

• Includes a video that shows the entire process for the experiment
• Explains some safety tips to consider when conducting the activity
  

Cons

• None
