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 (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 activity, learners explore why they can see colors in bubbles and why they change.

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 hands-on botany activity, learners sprout vegetables in film canisters.

In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

In this activity, learners determine the necessary conditions for pea seed germination.

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 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.

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

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

Learners use two mirrors to explore how images of images of images can repeat forever.
