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...

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

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.

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

Learners 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. Learners observe the rates of reactions of chalk, hamburger,...

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...

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...

Young scholars 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...

Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Students 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 temperature and...

Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...

Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.

Tenth graders test their saliva for enzyme activity. In 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.

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

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.

Students explore enzyme catalysis through a series of experiments. In this chemistry lesson, students determine the factors affecting catalysis. They explain the different uses of this process.

Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

Students observe demonstrations to show factors that affect rates of chemical reactions. In this rates of chemical reactions lesson, students investigate how catalysts, reactant concentrations, temperature and surface area affect the...

Students determine the meanings of concentration, surface area, and catalysis through an experiment. In this lesson about chemical reactions, students participate in an experiment. Students complete three different parts of the...

Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
