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 activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

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 fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

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 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 on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

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

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