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.

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.

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

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

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

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