From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this activity, learners explore clouds and how they form.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

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

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

This three-part activity shows learners how to build three meteorology tools: a wind vane, a rain gauge, and a barometer.
