# Bending Light

Explore bending of light between two media with different indices of refraction. ... (more)

Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows. (less)

# Disappearing Glass Rods

In this optics activity, learners discover how they can make glass objects ... (more)

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 reflection and refraction affect what we see. Use this activity as a demonstration or allow learners to experiment on their own. (less)

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen. (less)

# Polarized Light Mosaic

In this activity, learners use transparent tape and polarizing material to create ... (more)

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 discover that rotating the polarizer as they view the patterns causes the colors to change. With a little creativity, learners can also create colorful renditions of objects or scenes. Use this activity to introduce learners to concepts related to light and optics including polarization, index of refraction, and wavelengths. (less)

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly. They will be surprised when they place the stirring rods in a jar of vegetable oil and the rods appear practically invisible! This is a dramatic demonstration that effectively illustrates how light can bend and fool the eye. (less)
