In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this activity, learners build water-propelled engines from soft drink cans.

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.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

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.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

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

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.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
