In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

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.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

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

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

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 trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

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

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

In this activity, learners make their own heat waves in an aquarium.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

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 activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

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 activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.

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