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

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

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.
