Cumbersome Cubes
Halving is not always so simple. Small groups build a cube and then determine how to construct a cube that is half the size. Groups create two cubes, one that is the correct size and another that would be an alternative solution. To...

Ace in the Hole
How does inertia affect an object's trajectory? After watching a video on safety belt use, pupils discuss the notions of inertia. Using their knowledge, individuals try to drop a ball on a target while running, and classmates observe the...
