In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

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 their imaginations and picture a scene in their heads.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

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

In this activity, learners will explore how light can refract or break apart into different colors.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

In this activity, young learners will explore light and darkness through flashlight play.

In this activity, learners will build a model of a nebula using cotton balls and colored water. Astronomers photograph nebulas and add colors to provide information about the nebula's composition.

In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this activity, learners investigate how some butterfly wings get their color.

In this activity, learners use simple materials to create giant bubbles.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

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.

Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.
