In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

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 activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

This is a classic exercise for visualizing the scale of the Solar System.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
