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 explore light, color and rainbows by making their own rainbow glasses.

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 activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

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.

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

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 hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

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 environmental activity (page 6 of the PDF), learners identify household products that are recyclable and explore the different types of recyclable plastics.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

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 assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.
