In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

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 different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this optics activity, learners use paint thinner to make a small jar seem to disappear inside a larger jar.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

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.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

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

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

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this activity, learners explore their eye pupils and how they change.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

This activity gets learners looking at 6-sided shapes in nature, including the cells of a beehive, as well as other shapes.

This activity teaches combustion as the interaction of a fuel source and oxygen.
