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 optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners overlap the three primary colors to see how all other colors are made.

Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

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

In this activity, learners discover that it's difficult to distinguish between two different shades of gray when they aren't separated by a boundary.

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.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

This science activity demonstrates the dominant eye phenomena. What does your brain do when it sees two images that conflict?

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative 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 activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an

Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).
