In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.

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

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

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

In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.
