In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

Learners draw and cut out shapes of organs from construction paper. Then they attach these organs to the body of one learner to make a life-sized map of all the internal organs.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.
