Create Your Own Kaleidoscopes

For this light and the eye worksheet, students perform eight tests to show the blind spot in the human eye, to demonstrate Benham's disk, to show how polarized lenses work, to show how light scatters, to demonstrate fiber...

Many people know that fiber optics are used in delivering the Internet, but are surprised to learn they are also used in astronomy. Scholars explore light, reflection, and fiber optics through hands-on activities. They discuss...

Young scholars study the history of the invention of the kaleidoscope by Sir David Brewster. They create a kaleidoscope using art supplies.

This well-designed presentation covers many important aspects of the science behind light. In it, pupils view slides that have a lot of the important vocabulary associated with science, slides of famous scientists who made important...

Second in a series on optics, this video will inspire viewers to consider optical engineering. Several optical engineers are paraded onscreen, sharing a tip about the field or tidbits about how they pursued it. Show this video, along...

Different colors of the spectrum travel at different speeds through media, causing them to refract at different angles—which allows humans to see their colors. Through a simulation, pupils see how air, water, and other media bend light....

A prism breaks light into its seven colors to show the visible spectrum. Colored circles of light are combined to show that the primary colors can be incorporated to create every color imaginable! It seems to end abruptly with a...

Pupils construct kaleidoscopes to demonstrate how an image is multiplied by angled mirrors before light rays reach their eyes. They follow step-by-step directions to create a kaleidoscope, and draw illustrations of the repeating patterns...

Students are given a mnemonic device to review the light spectrum as it relates to the different components of refracted light. For this components of light lesson, students read Light Magic and review the properties of light. Students...

Students explore the properties of light. In this light activity, students investigate visible light by viewing a website, examining an electromagnetic spectrum chart, and observing light demonstrations. Students write about their...
