Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

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

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this optics activity, learners explore how light bends and affects what we see.

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, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

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 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.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

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

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.
