In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

In this activity, learners observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

In this activity, learners use their imaginations and picture a scene in their heads.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

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

In this activity about light and perception, learners create and observe moire patterns.

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

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

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

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.
