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 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 explore how nanosized structures can create brilliant color.

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

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

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 pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

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.

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

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

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

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

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.
