This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

On an airplane trip, learners have an opportunity to investigate the properties of air pressure at different altitudes.

In this activity, learners explore rocketry and the principals of space flight.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

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

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.
