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

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

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 make their own pinhole viewer in order to measure the size of the sun.

Did you know that using a lens one can bend light to make pictures of the world? It's true!

In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.

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 explore light, color and rainbows by making their own rainbow glasses.

This is an activity about turbidity, or the amount of sediment suspended in water.

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

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

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

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.

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.
