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

Learners construct and launch paper helicopters.

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

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

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.

Learners build simple catapults and use them to launch cotton balls.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Learners investigate how drag affects the falling rate of objects.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

Learners build devices from rubber bands to test for invisible air pollutants.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

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 model directed evolution by making paper fly. Learners construct and fly paper airplanes.
