Enzymes are so difficult for students to visualize- but not anymore! In this simple and inexpensive lab activity, students will observe the reaction of catalase (from potatoes) by mixing it with hydrogen peroxide.
Students test 4 reactions to determine the effects of acids and temperature on the effectiveness of the catalase:
-Potato + water
-Potato + hydrogen peroxide
-Potato + vinegar + hydrogen peroxide
-Cooked potato + hydrogen peroxide
This resource includes:
1. Teacher instructions with materials list and extensions for independent study
2. A narrated video demonstration of the lab
3. Student lab worksheets with background information about enzymes and discussion questions to demonstrate understanding
4. Teacher answer key
Your students will love this simple and effective lab to aid in comprehension of enzymes!
