Kids learn about the science of the light spectrum. Wavelengths and frequencies of the electromagnetic waves including visible light, primary colors, and subtractive colors.

In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

Read about the visible light spectrum and learn the frequencies and wavelengths for each of the primary and secondary colors.

In this introduction to light energy, students learn about reflection and refraction as they learn that light travels in wave form. Through hands-on activities, they see how prisms, magnifying glasses and polarized lenses work. They also...

This lesson contains the following labs: Rainbows, Refraction with Prisms, and What Color Is It? Students will study light by reading various nonfiction texts and viewing a video lesson. Then students will engage in the following labs:...
