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

Kids learn by experimenting with science. Project about the light spectrum.

This video segment adapted from FRONTLINE introduces the electromagnetic spectrum and explains how the various types of electromagnetic waves are distinguished by the amount of energy each wave carries.

Here is a large collection of simple science class activities for understanding the physics of light.

[Free Registration/Login may be required to access all resource tools.] Students investigate the fundamentals of light including its source, how it is defined for measurements, how we perceive color, and the situations that make an...

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

In this lesson plan, the electromagnetic spectrum is explained and students learn that visible light makes up only a portion of this wide spectrum. Students also learn that engineers use electromagnetic waves for many different...

We will reintroduce the students to the electromagnetic spectrum and visible light. We will talk about the states of electrons(ground and excited). The teacher will show a video link (Electrons in Atoms). We will then perform the science...

An interactive PowerPoint will be used to introduce the electromagnetic spectrum. Young scholars use UV beads to observe changes caused by the sun's rays and evaluate sunscreen effectiveness. Harmful effects of UV exposure will be...

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...

In this activity, students make simple spectroscopes (prisms) to look at different light sources. The spectroscopes allow students to see differing spectral distributions of different light sources.

Explains the difference between an emission spectrum and an absorption spectrum, and describes each as well as their applications.

For this very detailed lesson plan from NASA, students investigate wavelength and frequency within the electromagnetic spectrum.

Describes the characteristics of light, presents two formulas for calculating its wavelength, and provides a table of the different wavelength ranges across the electromagnetic spectrum.

This activity is designed for learners to apply their knowledge of mathematics and physics to "real life" situations. Students are presented with the situation that they are on a camping trip and wish to know the wavelength emitted by a...

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:...

This high school resource shows how the blue of the skies and the red of the sunsets can be explained by the interaction of sunlight with atmospheric particles which causes scattering of light.

Students create and decorate their own spectrographs using simple materials and holographic diffraction gratings. A holographic diffraction grating acts like a prism, showing the visual components of light. After building the...

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...

Analyze light by creating a CD spectroscope in this activity. See the whole spectrum of light with the spectroscope.

Students use the spectrograph from the "Building a Fancy Spectrograph" activity to gather data about different light sources. Using the data, they make comparisons between the light sources and make conjectures about the composition of...

Briefly explains the different types of radiation in the electromagnetic spectrum.

This Imagine the Universe site provides an introduction into the multiwavelength universe and astronomy. Site provides graphics, links to a quiz, facts on this topic as well as teacher resources.

Resource provides the ten signs that tell when a chemical change has occured. Each sign has a detailed explanation.
