In this engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

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

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

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

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
