Milk the resource for all it's worth. Young biologists perform assay techniques to test the digestion of protein. They place bacterial samples, fungal samples, trypsin solution, and distilled water on a milk-agar plate to see the effects...

Enzymes have a need for speed! What happens when they are forced to slow down? A well-rounded lesson plan from the K20 Center examines enzyme activity through role playing and a lab. Biology scholars work in teams and pairs to understand...

Digestion is an amazing and complicated process that provides humans with the energy they need to survive. Lesson six in this series on the science of food uses sliced turkey and a meat tenderizer to demonstrate how enzymes help break...

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!

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

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...

In this anatomy worksheet, young scholars complete 22 review questions in the format of short answer, table completion, and fill in the blank after finishing an online virtual experiment about the chemical and physical processes of...

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.

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

Students 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 solving...

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 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...

Now you have a new excuse not to do your homework. A long-term experiment has learners explore cellulose-digesting enzymes. They simulate how paper breaks down in a compost bin. There's no need to blame your dog for eating your homework...

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 compare different DNA and run a gel electrophoresis.  In this DNA instructional activity students complete a DNA activity that allows them to better understand its structure and function. 

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.

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

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

Students explore digestion. In this Human Body lesson plan, students participate in six different activities pertaining to the Digestive System. Students gain understanding of digestion through experimentation and investigation. Students...

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...

Students compare the different rates of reaction between an apple covered with vitamin C and an apple with no vitamin C. They compare the different rates of reaction between an apple placed in the sun and one not exposed to the sun. ...

Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...
