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

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

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.
