Description

Enzymes are so difficult for students to visualize- but not anymore! This enzyme lab experiment is simple and inexpensive, allowing students to easily observe the reaction of catalase (from potatoes) by mixing it with hydrogen peroxide.

Please note: This lab is also included in my Full-Year Biology Curriculum and Biology Unit 2: Chemistry of Life.

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 tips for differentiation

2. Guided on-level student instructions to test pH and temperature

3. Honors student instructions for creating an experiment to test pH or temperature

4. Answer keys

➤Why choose this lab from Suburban Science?

• Instructions are clearly laid out for teachers and students.
• Visuals aid in comprehension of concepts
• Discussion questions encourage critical thinking
• On-level and honors versions allow for quick differentiation
