In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

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.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

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

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

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

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

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this amazing activity about light and reflection, learners will use a pie plate and reflective strips from a mylar balloon to try to morph their face into a friend's.

In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

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.

Learners demonstrate how water can distort, refract and magnify light.

Like water drops in falling rain, a CD separates white light into all the colors that make it up.

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

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity (on page 2 of the PDF under GPS: Light and Color Activity), learners will see the illusion of colors produced by a rotating black and white image known as Benham’s Disk.
