In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

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

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity, learners make a photographic image--without a camera!

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

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

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

This activity (on page 2 of the PDF under SciGirls Activity: Forensics) is a full inquiry investigation into how hairs from a crime scene are matched to suspects.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

In this activity, learners make a photographic image—without a camera!

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 optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

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

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity, learners create a marble maze that contains sensors. As a metal marble triggers the sensors, the Pico Cricket turns on lights or spins motors.
