Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

Using simple, inexpensive items, learners build and test submarine models.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!

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

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
