This project investigates how different catalysts affect the rate of decomposition of hydrogen peroxide. By measuring oxygen production, understand how catalysts speed up reactions.
Using a catalyst will significantly increase the rate of hydrogen peroxide decomposition, resulting in more oxygen produced in less time.

Gather materials and put on safety equipment.
Measure equal amounts of hydrogen peroxide into three different test tubes.
Add different catalysts (yeast, baking soda, and control) to each test tube.
Start stopwatch immediately after adding the catalyst.
Observe and record the time taken for bubbling (oxygen release) to stop.
Repeat the experiment for accuracy.
Analyze the data to compare the effects of each catalyst.
Compile results and prepare a report.
It is expected that the test tube with yeast will show the fastest reaction rate, demonstrating the role of catalysts in chemical reactions.

Wear goggles and gloves when handling hydrogen peroxide. Conduct the experiment in a well-ventilated space.
Use graphs to show reaction rates clearly.
Include visuals of bubbling reactions.
Explain the importance of catalysts in everyday reactions.
Practice your presentation to enhance clarity and engagement.
Prepare to answer questions about reaction rates and catalysts.
Catalysts are substances that speed up chemical reactions without being consumed in the process.
Hydrogen peroxide decomposes into water and oxygen gas.
Yes, you can experiment with various catalysts to see their effects on reaction rates.
