A solid review of the excretion system that presents diagrams and asks learners to name the labelled parts or to identify which parts perform the particular jobs stated.

Biology lab technicians take a cheese sandwich apart as a demonstration of digestion. They record appearance and mass both before and after the process, which mimics chewing, acid action, and churning. Learners write their own lab...

Students analyze the similarities in different species. This lesson is part of a multi-segmented unit on the diversity of life. In this segment, students classify shoes to mimic the scientific categories of the classification system.

In this body parts worksheet, learners match words to definitions, categorize organs into systems, name functions of organs, and more. Students complete 5 activities.

Students investigate the digestive system. In this human biology instructional activity, students read an article about the digestive system and go onto a suggested website to review what they have learned. Students are asked questions...

Students explore biology by completing a human body worksheet. In this human brain lesson, students identify the different anatomy within the brain and the functions those pieces form. Students read an article about signals in the brain...

Students explore the systems that comprise the human body. In this human physiology lesson, students create a model of the human body and research a disease from a particular system. Students will then choose to either interview a person...

High schoolers explore disease caused by bacteria and viruses, how they are transmitted, and how they exert their effects on their hosts. They explain how diseases, such as AIDS, are spread by exponential growth.

Students explore various theories about laughter, laughter's effects on our mental health, and the benefits of laughter to our immune system.

Students investigate the circulatory system. For this circulatory system lesson, students complete a WebQuest and explore all the areas of the heart. Students determine the functions of different parts of the circulatory system and...

Students investigate how animals adapt to use its senses to identify foods that are nutritious or noxious. They determine how they associate foods with other things such as birthdays. They discuss the role of the nervous system in the...

Third graders explore the rotation of Earth and the moon. In this solar system lesson, 3rd graders participate in an Earth and moon simulation in which part of the class "becomes" the sun, while other children represent the moon by...

Students examine the functions of the heart and ways to maintain a healthy heart.  In this human body science instructional activity, students listen to Magic School Bus Inside the Human Heart, and diagram the human heart and blood...

In this biology worksheet, students find the words that are associated with the respiratory system and the answers are found at the bottom of the page.

In this nutrition worksheet, learners 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 short...

Fifth graders make their observations about the structure of the human heart. Students trace the flow of blood through the human heart. They touch a model of the human heart, 5th graders read aloud a handout that is found in their...

Sixth graders explore the internal organs of grasshoppers. They determine the function of the organs through a dissection activity.

Second graders explore multiple intelligences in each lobe of the brain.

In this health learning exercise, middle schoolers find the words that are about the bones of the body and the answers are found at the bottom of the page.

Students study the respiratory system, the lungs and air.  In this respiratory instructional activity students describe technologies that engineers have found that improve the health of the respiratory system. 

Five questions are presented and answered as a means of delivering information on the respiratory system. Using red and blue game chips, physiology learners model the movement of blood through the lungs. Groups of learners time how long...
