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.

Learners develop an understanding of air pressure in two different activities.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

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

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

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.

Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

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

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

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.

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.

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.

Investigate how force and thrust work to propel rockets into outer space. Build a rocket: a blown-up balloon taped to a drinking straw threaded through some string.

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

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

This activity was designed for blind learners, but all types of learners can participate to learn about conservation of gas. This is one of the classic experiments using baking soda and vinegar.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.
