The Digestive System: Where Does Food Go?
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...
Baylor College
Digestion
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...
Curated OER
Enzymes and Catalysts
Learners 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...
Curated OER
The Digestive System: An Overview
Young scholars label main structures of the digestive system, describe each structure's function, and describe sequence of events involved in digestion.
Curated OER
From One End to the Other
Seventh graders trace a piece of food through the digestive system. They describe the functions of the mouth, esophagus, stomach, etc.

What Happens When You Eat?
Students explore digestion. For 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....
LABScI
Enzymes: The Spit Lab
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...
Curated OER
Catalysts and Enzymes
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...
Curated OER
Are Enzymes Specific for Their Substrates?
Young scholars 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...
Curated OER
Enzymes
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.
Curated OER
What's on Your Plate?
Young scholars demonstrate the path of food in the body. In 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.

Yum - Yum!! - The Digestion Lesson
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.
Curated OER
Enzyme Lab
Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.
Curated OER
Amylase
Students examine what amylase is and its history. In this digestive lesson students study the effect amylase has on starch and how temperature affects the rate of activity.
Curated OER
From One End to the Other
Seventh graders become more familiar with how our food is broken down mechanically and chemically. They also trace the food through the alimentary canal.
Curated OER
Science Concept Maps
A collection of concept maps has some terms filled in and others left blank for young scientists to fill in. This library can provide you with many pop quizzes for all of your middle to high school science curriculum.

COMPARISON OF FOUR-, SIX-, AND EIGHT-bp CUTS IN CALF THYMUS DNA
Students use this laboratory exercise, restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. Assuming that the four component nucleotides (A, C, T, G) are distributed randomly within a DNA molecule, then any...
Curated OER
From One End to the Other
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.
Curated OER
Carnivorous Plants
Students 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.
Curated OER
Lactose Intolerance
Students are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...
Curated OER
Diversity And Adaptations Of Organisms
Seventh graders demonstrate the processes of science by posing questions and investigating phenomena through language, methods and instruments of science. They study the body features or systems of several animals.
Curated OER
Disease Fighters
Students study how the human body fights off disease causing agents. In this human health lesson students study the use of antibiotics and the problems misuse can cause.
Curated OER
Comparison of Four-, Six-, And Eight-bp Cuts in Calf Thymus Dna
Students investigate the use of restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. They utilize restrictive endonucleases to cut Thymus DNA and compare results by viewing the DNA fragments on Agarose Gel...
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
