"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

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

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

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.

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.

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

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

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

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

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.
