In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

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

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

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

This fun and simple hands-on astronomy activity lets learners explore model planets (that they or an educator will create), using methods NASA scientists use to explore our Solar System.

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.
