Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this activity (page 1 of PDF under SciGirls Activity: Forecasting), learners will construct an air cannon by cutting a hole in the bottom of a bucket and stretching a garbage bag over the other end

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this quick activity, learners observe how wind creates ocean currents.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

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