Twelfth graders investigate the refractive index of water. In this physics lesson, 12th graders explain the operation of laser. They write a lab report about the activity.

Students discover how light reflects off surfaces. In this hands-on demonstration, students examine how variations in color are produced by light interference.

Young scholars are introduced to the topic of light interference through this hands-on activity. They observe how light reflects off two surfaces and then meets to form an interesting variation of color on a film surface.

Investigate the properties of light by exploring the color effects produced when light is shone on soap film.

Using straws and soap, you can create geometric shapes to make a colorful art display when light shines through them.

In this experiment you learn how to generate carbon dioxide inside a container, and float soap bubbles above the gas. Once the bubbles are suspended, it is possible to observe them closely, which is normally very difficult to do....
