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

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

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.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

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 make their own heat waves in an aquarium.

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

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

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

This activity generates learner excitement about light through the creation of a room-sized rainbow.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

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

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

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