Learning about enzymes is important to build basic skills and an understanding of biological processes. An enzyme is a protein that helps chemical reactions to occur in the body. Digestion, for example, wouldn’t be possible without enzymes. In order to help students better understand the ability of enzymes, teachers often assign labs and lab reports. The experiment activities below explore how enzymes react under different experimental conditions such as temperature, pH, and time. Each enzymatic activity is engaging and can be adapted for any level of science class. Here are 13 enzyme lab report activities for you to enjoy.
1. Plant and Animal Enzyme Lab
This lab explores an enzyme that is common to both plants and animals. Firstly, students will explore important concepts about enzymes; including what enzymes are, how they help cells, and how they create reactions. During the lab, students will look at plants and animals and discover enzymes that are common to both.

2. Enzymes and Toothpicks
This lab explores enzymes using toothpicks. Students will practice different simulations with toothpicks to see how enzyme reactions can change with different variables. Students will look at enzyme reaction rates, how enzymes react with substrate concentration and the effect of temperature on enzyme reactions.

6. Enzymes in Laundry and Digestion
In this activity, students will take a look at how enzymes to aid digestion and laundry. Students will read A Journey Through the Digestive System and Amazing Body Systems: Digestive System, along with watching several videos in order to prepare to discuss how enzymes aid in digestion and the cleaning of clothes.

7. Lactase Lab
Students investigate the enzyme lactase in rice milk, soy milk, and cow’s milk. During the lab, students will be able to identify the sugars in each type of milk. They will run the experiment with and without lactase to assess the glucose levels in each sample.

8. Catalase Enzyme Lab
In this lab, students assess how temperature and pH affect catalase efficiency. This lab uses potatoes to measure how pH affects catalase. Then, students repeat the experiment by changing the temperature of either the potato puree or the hydrogen peroxide to measure the effect of temperature on catalase.
