Students are introduced to an engineering challenge in which they are given a job assignment to separate three types of apples. However, they are unable to see the color differences between the apples, and as a result, they must think as...

Remote sensing, false-color satellite images, and the electromagnetic spectrum are all covered in this fun site about Echo the bat. These topics are addressed in both a story book and text book fashion and are supported by a full set of...

In this interactive tutorial students will look at the energy stored in the magnetic field of an inductor. Self-inductance and mutual inductance will be distinguished and circuits with capacitors and inductors, or LC circuits will be...

One of the "Episodes in Romantic Science," this is as complete as a biography gets without being a book. Includes great information about Oersted and his electromagnetic work, The definitive source. Heavily footnoted with many additional...

An interactive simulation that teaches about electromagnetic radiation, dipole radiation, and electric fields by observing the effects of changes in sinusoidal, circular, and linear motion on the outward propagation of radiation. This...

Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting...

Students are presented with a challenge question concerning color blindness and asked to use engineering principles to design devices to help people who are color blind. Using the legacy cycle as a model, this unit is comprised of five...

Students learn the basic properties of light--the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic...

Contains an article on the life of scientist Michael Faraday and highlights his work in the study of electromagnetism. Archived.

Explore the electromagnetic spectrum and learn about each type of energy on the spectrum.

Exploratorium Science Snacks are miniature science exhibits and experiments that can be made with common, inexpensive, easily available materials. These electricity snacks represent a set of devices that you can build and experiment with...

College-level physics course highlighting electromagnetism. This course also includes a wide variety of other physics topics including lightning, electrocardiograms, metal detectors, and atom smashers, to name a few. Course includes a...

In this interactive activity adapted from the University of Utah's ASPIRE Lab, students will investigate frequency in terms of trampoline jumps, pendulum swings, and electromagnetic waves.

Brief biographical sketch of Michael Faraday, famous scientist whose discoveries include electromagnetic rotation, Benzene, electromagnetic induction, and Laws of Electrolysis.

A gallery of astronomy images which depict galaxies, comets, the moon, planets, nebulae, supernovae as seen in various regions of the electromagnetic spectrum. Each image in the gallery is described. Fascinating!

Investigate the science of radio astronomy, and create a model of a curved reflecting dish that will work like the Arecibo detector to detect electromagnetic waves. Explore risk using a risk space grid.

This page and the three pages which follow discuss how X-ray technology can be used to produce an image of the human body. Discussion is understandable and highly intriguing. Several interactive animations allow the visitor to explore...

Our magnets are like world-class athletes - Team Tesla, if you will. They have an awful lot of power, but to stay in that kind of shape, they need to eat and drink - a lot.

A discussion of the Advanced Light Source (ALS) facility and its use in material analysis and medicine.

Using an interesting and intriguing format, this page discusses the question of "How does one measure the speed of light." Explanation focuses on Galileo's and Roemer's efforts to obtain a reasonable value. Also discusses Heinrich...

A bar magnet model built by placing a group of magnetic dipoles along the magnet. This simulation shows the magnetic field of a bar magnet, and has a movable compass which shows the magnetic field values.

Here's a whole different look at Faraday. His religion, Sandemanian, greatly influenced both his life and his science. This article looks deeply at that aspect of his life.

Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through...

This unit allows students to investigate the cause of a speaker's vibration in addition to the effect.
