In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

Can gelatin (like Jell-O ®) change the speed of light?

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity, learners discover that the human brain is highly adaptable. Learners try to toss beanbags at a target while wearing prism goggles.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

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

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

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 set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.
