In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.

In this online Flash game, learners will captain a sailing challenge, adjusting boat direction and sails, seeking the way to take greatest advantage of varying wind speeds and directions to catch the

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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

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

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
