Use this great overview to give information on all aspects of nutrition. By working their way through this PowerPoint, students review a lot of information about the digestive process.  Students read many facts on a number of...

Around the world, about 2/3 of adult humans are lactose intolerant. Scholars work in small groups to discuss a few statements about lactose intolerance. Then, they watch a video on the topic and readdress each statement. Whole-class...

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...

Storing and transferring energy is explained here with reference to the fight or flight response, along with the need for activity in times of lowered nutrition. This is a great summary of ATP applications, and after the multiple stages...

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...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Students examine what amylase is and its history.  For this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.

Students examine the characteristics of lactose and lactase.  For this enzyme lesson students study the lactose in milk and its rate of dissolution.

Students experiment with lactase to find out how milk sugar is broken down in the body. In this enzyme lesson, students use glucose strips to investigate the breakdown of lactose into glucose and galactose for milk digestion in the human...

Students explore the various components of the digestive system and learn about both the physical and chemical processes that work together to break down food into absorbable molecules.

In this science worksheet, students read about enzymes and nutrition. Students also answer 2 comprehension questions about the reading.

Seventh graders trace a piece of food through the alimentary canal and differentiate between mechanical and chemical digestion in several different hands-on activities related to digestion.

Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

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

Students explore the breakdown of proteins. They cut wells in Jell-O and observe as the detergent digests the Jell-O. Students record their observations and take measurements.

Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

A complete overview of oxidation, reduction, and how electrons are moved in respiration. You could use this slide show to elaborate on the concept of harvesting stored energy, and to summarize the stages of aerobic and anaerobic metabolism.

Students demonstrate the path of food in the body. For this biology lesson, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.
