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...

Students test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

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.

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...

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...

Students explore how proten biotechnologies can be used to diagnose infectious disease specifically how ELISA uses immunological principles as well as enzymes to diagnose patients, and with specifics with HIV. They perform a successful...

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 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...

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...

Students perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...

Students discover how restriction enzymes work, while learning the importance of restriction enzymes in studying DNA structure.

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

Young scholars test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.

Students research and define a muscle biology research question and organize an experiment to address the question utilizing either NADH staining or acid buffering. They analyze data as well as draw conclusions about their research....

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 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...

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.

Learners explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.

In order to understand DNA fingerprinting, advanced biology aces divise a crime scenario and analyze three different samples of lambda DNA. This creative lesson plan provides practice with micropipettes, electrophoresis boxes, and other...

Students work with whole plant material and are not required to measure small quantities, yet they can see evidence of transformed plant cells (plant cells that have genes from bacterial plasmids). This is a laboratory suitable for...

High schoolers 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...
