This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

Our bodies produce snot, or mucus, that we blow from our noses. In this activity, learners will create a model of how snot works and will explore how it keeps our bodies healthy.

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.
