Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

Explore the function of enzymes through a series of lab investigations. Learners use household enzymes such as hydrogen peroxide to model the role of enzymes. The enzymes break down proteins with and without a catalyst.

Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Students explore biochemical reactions mediated by enzymes in an inquiry approach. They are given two questions about the types of living materials that contain the enzymes that break down hydrogen peroxide, and under what conditions the...

Using an inquiry approach to studying biochemical reactions, cooperative teams of pupils investigate hypotheses about living materials that contain enzymes which break down in hydrogen peroxide. They perform experiments, practice...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

Students explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.

Tenth graders test their saliva for enzyme activity. For this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.

Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

Young scholars explore how enzymes are important in the chemical reactions of all living things.  In this enzymes and catalysts lesson students complete an activity to see how enzymes change living things.

Students pretend to be enzyme that breaks toothpicks in timed intervals. They complete calculations to determine how many toothpicks are broken per second to determine the rate of reaction of the enzyme.

High schoolers investigate the enzyme catalase. In this enzyme lesson plan, students observe a normal catalase reaction, they observe liver tissue, potato, chicken and apple for the enzyme catalase and they study the effects of...

High schoolers explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...

Young scholars participate in a modified demo enzyme lab, a "magic show." The purpose of the demo is to tickle the curiosity of the student and grab their interest before discussions of enzymes. Its purpose is also to stimulate problem...

Students explore the role of enzymes in chemical reactions. In this enzymes lesson plan, students use hydrogen peroxide and manganese dioxide to observe a chemical reaction. Students observe the rates of reactions of chalk, hamburger,...

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

Students explore enzymes and what can inhibit and act as a catalyst for them.  In this enzymes lesson students complete experiments on enzyme properties.

Students discover enzyme to substrate specificity. The experiment uses samples of glucose and lactose in combination with the enzyme lactase. Students observe the reaction between the lactose and the lactase; the lack of a reaction...

Students explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation. This lesson is...

Pupils observe the effectiveness of detergents on breaking down proteins.  In this investigative lesson students participate in an activity that shows how proteins are broken down in gelatin and fill out a worksheet. 

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

Students work with models of substrates and of enzymes and test the digestion of lactose with lactase. They determine if digestion of lactose has or has not occurred.
