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.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

Learners engage in close observation of falling objects. They determine it is the amount of air resistance, not the weight of an object, which determines how quickly an object falls.

Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

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