In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

In this activity, learners make a Benham Top to explore visual illusions and optics.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.
