In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape. In doing so, learners will experience many of...

In this activity, learners build bridges and cantilevers in a series of "building out" challenges with straws and pins. In doing so, learners will experience many of the basic physics and...

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape. In doing so, learners will experience many...

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. keep things the same shape but change the...

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes. Learners use simple materials to assemble a comb (electrophoresis chamber) to...

If a sailboat is stranded because there is no wind, is it possible to set up a fan on deck and blow wind into the sail to make the boat move? In this activity, learners explore this classic physics...

In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet. Educators can...

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes. During the first round, they calculate the average distance the planes fly and...
