In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.

In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this activity, learners design wind-powered cars out of simple household materials. Students have fun designing and then racing their vehicles around the room.

In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.
