In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

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).

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.
