In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?

In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

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 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!

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

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

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 activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this activity, learners construct a device that allows them to look over ledges or around corners.

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 data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

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).

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

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.
