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 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...

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...

Learners use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...

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 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...

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

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.

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...

Students conduct a variety of experiments to explore gel electrophoresis. For this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students use the exercise as a prelude to a "wet" lab or as a substitute for such a lab. It correlates well with colony transformation labs. This lab is recommended for students what have difficulty with the abstractions that genetic...

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 conduct a variety of experiments to explore protein. In this biology lesson, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription and translation...

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 watch a demo which is a modification of an enzyme lab which is done as a "magic show". It's primary purpose is to tickle the curiosity of the student and grab interest before discussion of enzymes. It is also used to stimulate...
