Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and tasty treats to...

Break hearts with this lesson plan: chicken or sheep hearts, that is! Your class examines the external and internal structure of the heart with a dissection activity. A handy anatomy resource provides the necessary materials for...

What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

How can the circulatory system compare to a city map? Pupils distinguish the "roadways" and "vehicles" of the cardiovascular system, compare the anatomy and function of veins and arteries, and review different types of blood cells with...

What a festive way to examine what happens to the heart in different gravitational situations! Small groups place a water-filled balloon in different locations (on a table top, in a tub of water, and held in a vertical position), drawing...

Lub-dub, lub-dub. Why does the heart beat? Why does blood circulate throughout the body? Life scientists find out how important circulation is for dissolving and dispersing materials by timing how long it takes for food coloring spread...

Anatomy and physiology fans imitate how blood flows from place to place in the circulatory system. After constructing and calibrating their own measurement cups, learners discover that different sizes of vessels transport various volumes...

Circulate this news: the heart is a pump containing one-way valves! Following the previous instructional activity on the external structure of the heart, learners now take a look at the inside. They use a three-color diagram to label a...

With a partner, youngsters measure their pulse and breathing rates, both at rest and after running in place for a minute. While this activity is not novel, the lesson plan includes a large-scale classroom graphing activity and other...

With the thousands of tasks our brain consciously performs on a daily basis, it's amazing that breathing isn't one of them. Learn how human bodies are able to automatically control the exchange of gas that keeps us alive with this short...
