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 outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

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).

In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.
