This video focuses on enzymes and the AP Biology Lab: Measuring Catalase Activity: Using Sodium Alginate Yeast Spheres.

You can collect data from the trials in this video - and make graphs with the data.

I got the idea for this lab here, from Pamela Bryer. Thanks!

This lab fits into the AP Biology curriculum in Unit 3: Cellular Energetics, under 3.3 Environmental Impacts on Enzyme Function. It can be adjusted and scaled for non-AP Biology classes as well as middle school classes.

This lab can be done in many ways - I'd love to hear your thoughts and feedback in the comments. What works for you? What hasn't worked?
