This digital textbook covers core physics concepts and includes interactive features, real world examples, videos, and study guides.

Learners explore electrification in the 20th century. Some topics investigated are rural electrification, power generators, and direct current (DC). The resource consists of historical information, a timeline, and a personal essay by a...

Explains what electromagnetic energy is, the history of its discovery, some terms used when talking about it, and gives some facts about it.

This ScienceWorld site describes the Scottish mathematician and physicist James Maxwell (1831-1879) who published physical and mathematical theories of the electromagnetic field.

Discusses the development of a new rocket engine that operates by the ion propulsion as opposed to gas propulsion. Well written and great graphics!

A solid telling of Oersted's scientific achievements, along with some interesting insight into Oersted's personal beliefs. Many links.

In this lesson, learners will investigate what they can do to produce a stronger electromagnet. Students will use the scientific thinking process to conduct investigations and build explanations. They will present their discoveries to...

A simulation of the Rutherford experiment. Includes an animation and an explanation of the history behind the experiment.

A set of four online courses in Physics for elementary and middle school teachers. Each course targets a different topic area - light, electricity & magnetism, temperature & heat, and force, motion, & energy.

This site features numerous interactive resources (such as simulations, interactive exercises, experiments, etc.) designed for teachers and students of the physical sciences. Some of the resources are available only on CD-ROM, but most...

An article that discusses the coupling of an electric field with a magnetic field to create electromagnetic waves. Article also discusses how different types of electromagnetic waves have different wavelengths which forms the...

Discusses the connection between electricity and magnetism and the early work of Michael Faraday and James Clerk Maxwell. Electromagnetic interactions were first described by Maxwell. Continues on with a discussion of quantum physics and...

A really fine and complete biography, quite lengthy. Some emphasis placed on his time at Princeton. A great deal of detail can be found here. Link here to the Joseph Henry House.

This site from the Human Genome Project provides a large collection of facts and information, demonstrations, experiments and project ideas. Written for teachers but easily adaptable for any type of student work. A good site to check out...

Here you can find what you need to scientifically assess battery performance. In this exercise (that should take about one week) learn how batteries work, how they wear out and most importantly, how to make valid measurements to assess...

At this site read about Ernest Rutherford (1871-1937 CE), the scientist who was awarded the Nobel Prize in Chemistry, "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances." This...

The World Health Organization probes into the feared associations between electromagnetic fields (EMFs) and cancer. Check out "What is EMF?" for detailed summaries on what electromagnetic fields are and the possible health effects, or...

Shake N' Light flashlights have been advertised on televisions across the nation in the recent year. But many do not understand just how they get energy to light up the bulb without using batteries. Do this experiment to make your own...

Need a unit converter? Links to the most common converters provide access to the answers you need quickly.

Through labs, readings, videos, and discussions, students learn about the concepts of Electromagnetic Induction.

Text and animated graphic show how lightning is an example of a natural capacitor.

Inside your brain, you have over 80 billion neurons - tiny brain cells, all working together to make you the person you are.Neurons talk to each other by sending electrical messages. Each message creates a tiny magnetic field. If enough...

Students face a game-like challenge to use electrostatic forces to move a charged puck into a goal. By placing charges on the rink, a charged puck can be attracted and repelled around obstacles and into a goal.

Students will demonstrate how an electric current can make an iron object magnetic by building an electromagnet with a steel nail, insulated wire, a simple switch, a battery/cell, and small metal washers. Students predict the number of...
