Curated OER
Endocrine Review Sheet
Starting with a diagram of the kidneys and urinary tract of the human, this sheet has questions about excretion, blood concentrations of hormones, gland feedback mechanisms and the effects of some hormones.
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.
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
Following Digestion of a Meal
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.
Curated OER
Chemical Energy
In this science worksheet, students read about enzymes and nutrition. Students also answer 2 comprehension questions about the reading.
Curated OER
Carnivorous Plants
Pupils 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
Endocrine System
In this endocrine system worksheet, learners 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 activity 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
Young scholars 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...
Curated OER
Worm Composting
Second graders discuss worm composting. In this decomposition lesson, 2nd graders look at the anatomy of the worm and how it eats food. They have their own worm bin and review what foods can and can not be given to the worms for...
Curated OER
They Don't Just Eat Grass
Students consider the USDA daily recommendations to create a "feed" product for middle schoolers. In this Health lesson, students learn about the ingredients in feed that is fed to livestock and apply the method to creating feed rations...
Curated OER
They Don't Just Eat Grass
Students explore and examine different types of feed used for livestock. They discuss types of feed, the need for energy and health, and create graphs of food compared to categories. Students organize data and complete worksheets on...
Curated OER
Investigating the Uses of Backyard Bacteria
Students discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.
