Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

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.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners determine the necessary conditions for pea seed germination.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners make a photographic image—without a camera!

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

In this activity about light and refraction, learners discover how a lens creates an image that hangs in midair.

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 optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
