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

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

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

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

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

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 discover how to determine the distance to a lightning strike or nearby thunderstorm.

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

In this physics activity, learners will explore buoyancy.

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

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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