Ins and Outs of Respiration

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 do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases...

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...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

NASA has crafted an imaginative and memorable series of lessons, "NASA and Jamestown Education Module." This lesson is one of the five components. In it, middle schoolers connect history and science by comparing the settlement of...

During this game, kids become migratory shorebirds and fly among wintering, nesting, and stopover habitats. If they do not arrive at a suitable habitat on time, they do not survive. Catastrophic events are periodically introduced that...

Collaborators sort a set of cards into biotic and abiotic categories. Then, as a class, they discuss their work and relate each of the abiotic components to climate change. Finally, they form a web of components by connecting those that...

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

Students are introduced to the respiratory system, the lungs and air. They learn about how the lungs and diaphragm work, how air pollution affects lungs and respiratory functions, some widespread respiratory problems, and how engineers...

Students investigate how pollution affects lung health. In this pollution and lung health lesson, students build lung models from a soda bottle and balloons, and then discuss how the emissions from fossil fuels can adversely affect lung...
