In this activity, learners use simple materials to create giant bubbles.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).
