In this activity, learners construct a simple air pressure launcher for paper rockets.

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

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.

In this activity, learners model ancient lunar impacts using water balloons.
