Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.

In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).
