Allelopathy: Do Some Plants Inhibit Growth of Others Science Project
Investigate the allelopathic effects of certain plants on the growth of others. Conduct experiments to observe the relationships between different species!
Investigate how different temperatures influence the rate of catalase activity in this exciting science project. You'll measure oxygen production and understand enzyme behavior!

If the temperature increases, then the rate of catalase enzyme activity will increase, up to a certain point.

Prepare test tubes with equal amounts of hydrogen peroxide.
Place potato pieces in each test tube.
Set one test tube in a cold water bath, one in hot water, and the rest at room temperature.
Measure the temperature of each test tube.
Start the stopwatch and observe the bubbling.
Record the time taken for bubbles to form.
Repeat the experiment for accuracy.
Analyze the data collected.
It is expected that the test tube at optimal temperature will show the highest enzyme activity. Cold temperatures may slow down activity, while extreme heat could deactivate the enzyme.

Handle hydrogen peroxide with care, avoid skin contact, and use gloves if necessary.
Use clear graphs to display results.
Include a video showing the reaction.
Prepare a poster summarizing your findings.
Practice explaining your experiment to classmates.
Anticipate questions judges might ask.
Catalase is an enzyme that breaks down hydrogen peroxide into water and oxygen.
Temperature affects the kinetic energy of molecules, influencing enzyme activity and substrate interactions.
Yes, catalase is present in many living organisms, including plants and other animal tissues.
