In this engineering activity, young learners investigate multi-level buildings.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners will engineer three different parachutes to test how well each one works.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.
