Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners overlap the three primary colors to see how all other colors are made.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this lab (Activity #1 on page), learners explore how we see color.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

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).

This is an activity exploring color and color mixing.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an
