In this radiation worksheet, students review the different types of radiation waves that come from space and the different telescopes used to detect this radiation. This worksheet has 17 true or false questions.

Students study emitted and absorbed light, and label each type of spectrum. They identify elements by their spectral signatures and use a spectroscope.

Students examine the Earth's magnetosphere and observe the effects of the sun's energy on it. They discover the difference between true north and magnetic north. They also explore how solar cells convert solar energy to electricity.

Students are introduced to the topic of electromagnetic induction. In groups, they describe ways in which the magnetic flux can change and discuss emf and current. They use different scientists laws and apply it to various scenerios in a...

Fourth graders examine the makeup of the electromagnetic spectrum and how the various forms of EMRs are similar and different from each other. They, in pairs, solve problems from worksheets imbedded in this lesson plan.

Students explain how electricity is transferred from source to load without actual wires connecting the two. In this physics lesson, students explore how wireless electricity was discovered. They cite practical applications of this...

Young scholars describe the science of physics. In this Physics activity, students observe examples of physics within their classroom. Young scholars create a definition for physics.

In this lesson students learn how AM radios work through basic concepts about waves and magnetic fields. Waves are first introduced by establishing the difference between transverse and longitudinal waves, as well as identifying the...

The discovery of radio waves, which was widely seen as confirmation of James Clerk Maxwell's electromagnetic theory and paved the way for numerous advances in communication technology, was made by German physicist Heinrich Hertz. In the...

In MRI, magnetic fields and radio wave pulses combine to get a unique, and medically beneficial, response from your body's hydrogen atoms. Take a peek in this tutorial.

This Beth Israel Deaconess Medical Center site offers a comprehensive look at MRI exam phases, preparation, technology, equipment, safety, and research. Images and labeled diagrams are also provided on this site.

Students are introduced to the electromagnetic spectrum through this group research activity. Each group investigates a different wavelength range within the em spectrum and reports back to class. Discussion ideas also included.

Karl Jansky discovered extraterrestrial radio waves while investigating possible sources of interference in shortwave radio communications across the Atlantic for Bell Laboratories, and is often known as the father of radio astronomy....

Sir Oliver Lodge's experiment demonstrating the first tunable radio receiver was an important stepping stone on the path toward the invention of a practical radio.

This site from MedicineNet.com gives an MRI description, why they're performed, risks, and patient preparation. A thorough explanation of the process is provided.

Nikola Tesla and Thomas Edison duke it out over the best way to transmit electricity and Heinrich Hertz is the first person (unbeknownst to him) to broadcast and receive radio waves.

For a man whose career involved the entire known universe, John Kraus had a remarkably insular upbringing. He was born and raised in Ann Arbor, Michigan, and earned his bachelor's, master's and doctoral degrees in physics, all at the...

NASA provides a nice blending of the achievements of three scientists, Oersted, Ampere, and Maxwell. This done by NASA-sponsored International Solar-Terrestrial Physics group. Lots of pictures, diagrams, and scientific explanation. Good...

This site from The Florida State University provides an informational page on electromagnetic radiation discusses the characteristics and properties of its many forms including X-rays, gamma rays, ultraviolet radiation, infrared...

This Florida State University page introduces light as an electromagnetic wave and discusses the frequency and wavelength range of the various regions of the electromagnetic spectrum. Includes links to some interactive Java applets.

A solid summary from the University of Oregon of the work of James Maxwell Clerk, Michael Faraday, and others in the field of electric and magnetic phenomena. This is a fine essay.
