In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

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

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.

In this activity, learners investigate passive solar building design with a focus solely on heating.

This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.
