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

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

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