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

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

Learners develop an understanding of air pressure in two different activities.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
