In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

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

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
