Colorful pictures and graphics make this a visually-appealing presentation on animal nutrition. Be aware that two of the sixteen slides include blank graphic organizers, so you will need to find the other existing version of this...
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
Small Intestine, Pancreas, Liver, and Gall Bladder
In this small intestine, pancreas, liver, and gall bladder instructional activity, students fill in the blanks with information about these structures of digestion. Students research information about organ of the digestive system given.

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.
Curated OER
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

In this digestion worksheet, students review the organs involved in the digestive process along with the function of these organs. This worksheet has 5 fill in the blank, 8 short answer, and 7 matching questions.
Biology Junction
Cellular Structure
The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...
Howard Hughes Medical Institute
Milk—How Sweet Is It?
Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...
Curated OER
Chemical Energy
In this science worksheet, learners read about enzymes and nutrition. Students also answer 2 comprehension questions about the reading.
Curated OER
Carnivorous Plants
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.
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
Kingdom: Fungi
The general characteristics of fungus types are presented here. Your class will love the pictures of the amazing features found on these strange living things. The internal and external structures and their functions are highlighted. By...
Curated OER
Endocrine System
In this endocrine system worksheet, students compare and contrast the glands associated with this body system plus review the four major classes of hormones. This worksheet has 25 fill in the blank statements.
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...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
