In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

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

In this activity, learners are invited to imagine the park of their dreams!

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