In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

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 build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners take on the role of environmental engineers as they design water filters.

Build and test a scale model of a rainforest canopy walkway.

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

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.
