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

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

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

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

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

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 lab (Activity #1 on page), learners explore how we see color.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

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 construct a device that allows them to view 2-D images in 3-D.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
