Try Angle

Students use an Etch A Sketch® device to trace a triangle shape, erase it, and repeat the trace a couple of times to test the effect that repetition has on the ease or difficulty of a task.

Memory Box

Two students work together - one opens a box and looks at the contents for 10 seconds then, with the box closed, tells the other student all the items remembered. The task is repeated with a second box. Will more items be remembered the second time?
