Transmit sound with an electromagnet. Class members follow the provided direction and build an electromagnet that will transmit sound though a cassette-tape player. As as extension they create an air core electromagnet and...

Things are about to heat up in your classroom! A kinesthetic lesson asks learners to play the part of the gases in the earth's atmosphere and interact with the sun's radiation. The focus is to learn the impact of the increasing...

Make a class set of spectrum tubes by first purchasing some diffraction grating, and then constructing the tools with mailing tubes or shoe boxes. If you aren't up for assembling them, you could purchase prepared spectroscope kits. This...

Hear from deep space. Pupils learn how satellites transfer information back to Earth. They learn about three different ways to modulate radio waves and how a satellite sends information with only 0s and 1s. Using sound, class members...

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...

Investigate a heated topic in environmental science. Scholars team up to play the parts of gas molecules in the atmosphere. As the teacher moves about, acting as the electromagnetic wave, learners react as their molecules would to the...

Learn about radiation, and what everyday items produce radiation, with a series of activities about heat transfer. Kids go over basic information about electromagnetic waves and ionizing radiation before performing several experiments...

Grab a partner and shed some light on light. A remote learning resource has scholars play a board game to answer trivia questions about light. They also read about how Einstein contributed to the understanding of light as both a wave and...

How do you demonstrate radio transmissions? Pupils build a low-energy radio transmitter by constructing two coils from magnet wire and connecting them to audio/phone plugs. The resource provides the details on how to build the...

With a little light and a lot of time, you can create some amazing images. This NASA-related task instructs pupils to build a pinhole camera. The lesson provides suggestions for different pictures to try with the pinhole camera...

Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.

[Free Registration/Login Required] An informational text about electromagnetic radiation and the effects it creates. A question sheet is available to help students build skills in reading comprehension.

Light is an example of an electromagnetic wave. Electromagnetic waves can travel through the vacuum of interstellar space. They do not depend on an external medium-unlike a mechanical wave such as a sound wave which must travel through...

Students apply everything they have learned over the course of the associated lessons about waves, light properties, the electromagnetic spectrum, and the structure of the eye, by designing devices that can aid color blind people in...

Visit this page to see an animation demonstrating the Doppler Effect. How do sound waves and electromagnetic waves behave similarly with this effect?

An easy experiment through which students learn about light rays and the electromagnetic spectrum. Requires a TV, its remote, and a hand-held, flat mirror.

This site provides background information, images, and an activity to help students understand the concept of radiation. Includes both the student pages and a teachers guide with lesson plan.

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

In this experiment, you will measure the speed of light using a microwave oven, some egg white, and a ruler. This short project proves to be an extremely interesting choice for a science lab, with pictures for illustration, and thorough...

What colors do you see in a bubble? Why do you see colors in a bubble? Use this site to find out the answer to these questions with this easy experiment.

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.

Several short descriptions of demonstrations pertaining to polarization principles. Suitable as a supplement for a teacher lesson plan or as an idea-generator for a student project.
