In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

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

This activity (on page 2 of the PDF under SciGirls Activity: Colorblind Dogs) is a full inquiry investigation into dogs' ability (or inability) to see color.

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

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

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.

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

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.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

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

In this activity, learners make a Benham Top to explore visual illusions and optics.

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.
