Electromagnetic Spectrum

Using a Maori legend, How Maui Tamed the Sun, youngsters are introduced to the importance of sunlight to civilization. Teach them about nuclear fusion that occurs to produce the solar energy we later receive on Earth as electromagnetic...

After investigating visible light and the electromagnetic spectrum students explain the concept that light can be considered an electromagnetic wave. They give two examples of how engineers use electromagnetic waves, and describe how...

Students listen as the teacher introduces Newton's early discovery of the diffraction of light. They use multiple sources of light (fluorescent, incandescent, sunlight, etc) to bend the light. They first use a prism then a diffraction...

Uncover the science behind the beautiful phenomena of rainbows with a simple demonstration. Shine light through different-sized containers of water as young scientists learn that rainbows occur when visible light is split up into its...

Take young naturalists on an exploration of the world's tropical rainforests with this extensive collection of lessons and activities. Whether its creating leaf and flower prints or investigating the absorption spectrum of chlorophyl,...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics from making...

After reading about radio transmission, application, and the difference between AM and FM, small teams of engineers use a kit to construct an FM radio and then send and receive broadcasts. This is an ideal activity for middle school STEM...

Get an up-close-and personal look at the sun from the safety of your classroom with this fun science application. Offering numerous activities, images, and videos, the resource supports children of all ages as they learn about the sun.

Let there be light in your classroom with a video that explains that light travels in waves, the electromagnetic spectrum contains seven colors, and the color of an object depends on which light waves it reflects and absorbs. With...

Learners discuss different ways engineers use light. In this engineering lesson, students are introduced to the properties of light and the way light is used. They view a demonstration of light waves using a slinky, and practice using...
