How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.

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

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

This activity (on pages 24-29) combines science and art to introduce learners to how different animal pollinators spread pollen from one plant to another, and how certain shapes, colors, and smells of

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

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

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

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

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.

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
