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

Pupils 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.

Seventh graders trace a piece of food through the digestive system. They describe the functions of the mouth, esophagus, stomach, etc.

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

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

In this digestive system worksheet, students answer 9 questions, 2 of which are multiple choice and 7 are short answer. Included are questions about the process of digestion and the structures of the digestive system.

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...

In this gene cloning activity, students are given a gene sequence of DNA, plasmid DNA, 3 restriction enzymes, their cut patterns and a DNA ligase. They answer 6 questions about the results of using different restriction enzymes to cut...

In this small intestine, pancreas, liver, and gall bladder worksheet, students fill in the blanks with information about these structures of digestion. Students research information about organ of the digestive system given.

After reading a short passage about the digestive system, kids demonstrate their understanding by responding to a series of comprehension questions.

Students perform restriction digests on DNA samples from four individuals, and then search for similarities between the individuals by running the restriction fragments on an electrophoresis gel.

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

Learners examine how carnivorous plants get their nutrients from animals.  In this food web lesson students examine how the plants attract their prey and are given many onilne sources to research.

In this digestive system learning exercise, students answer a list of true/ false questions. The students answer questions based on their knowledge of each process of the digestive system.

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...

For this nutrition worksheet, students review the organs and enzymes that are part of the digestive system. Then students review the food pyramid by comparing two menus. This worksheet has 9 fill in the blank, 4 true or false, and 5...

In this digestion activity, students review the organs involved in the digestive process along with the function of these organs. This activity has 5 fill in the blank, 8 short answer, and 7 matching questions.

In this digestion worksheet, students will match 12 terms associated with the digestive system to their correct definition. The vocabulary words review the digestive system organs and their functions.

Students examine the characteristics of lactose and lactase.  In 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...

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.

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.
