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 use tinfoil to build and test their own boats - which designs will float, and which will sink?

Most people will break a bone in their body at some point in their life, but how much force does it take to break one?

In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

In this activity related to magnetism and electricity, learners observe as two parallel, current-carrying wires exert forces on each other.

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 activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
