Scientists discover and probe x-rays and radioactivity, while inventors compete to build the first radio.

[Free Registration/Login Required] An informational text about how a compass works using electromagnetic force. A question sheet is available to help students build skills in reading comprehension.

Students will work in small groups to design at least one complete circuit using multiple materials. They will record their observations of how they created an electrical circuit using diagrams and notes in their journals. Using a...

Read about the device used for measuring resistance in a circuit which was discovered in 1843, but had been invented a decade earlier. The inventor's name was not Wheatstone.

An electromagnetic induction model that simulates an electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter.

Compasses had been steering people in the right direction for many centuries when, in the year 1820, one particular compass made a very different sort of revelation to an unsuspecting Danish science professor.

Explains electrical resistance and how it is measured using the formula for Ohm's Law.

Alternating current behaves differently, depending on what components are in a circuit.

Just a year after electromagnetism was discovered, the great scientific thinker Michael Faraday figured out how to turn it into motion. (Java tutorial)

An experiment to find out how an old-style doorbell works.

Two scientists share the credit for discovering, and then interpreting, the phenomenon of electromagnetism.

For this interactive activity, students will explore electricity and be able to design and create a complete electrical circuit. Students will also learn what is necessary to light a light bulb. Creative thought, ideas, and,...

See drawing from Hans Christian Orsted's lab notebook showing an experiment in which an electric charge passing through a wire seemed to create a magnetic field!

This set of activities has students using everyday items (batteries, magnets, compasses, iron and paper clips) to reveal the connection between electricity and magnetism. Ideally, students will already have experience building simple...

This instructional activity discusses the result of a charge being subject to both electric and magnetic fields at the same time. It covers the Hall effect, velocity selector, and the charge to mass ratio. Given several sample problems,...

This site provides a list of the topics and links to the Physics (Combined Science)courses offered in GCSE Bitesize and a list of contents of each. The topics include the following: Energy, Electricity, Matter, Radioactivity, Forces,...

Students can use these simulations to understand concepts in electromagnetism. Simulations are available on the following concepts: Lorentz Force, The Hall Effect, capacitor, conductor, transistor, cyclotron, static electricity....

Here is a project that is almost like a magic trick: with a strong magnet and a simple apparatus you can build yourself, you can make a coin "walk" up and down a wire coat hanger. This project is an interesting way to learn about the...

An interactive simulation that teaches about Faraday's Law, magnets, and magnetic fields by showing how a change in the magnetic flux can produce a flow of electricity. This simulation can either be downloaded or played online and...

Svante Arrhenius was born in Vik, Sweden, and became the first native of that country to win the Nobel Prize. The award for chemistry was bestowed to him in honor of his theory of electrolytic dissociation. Arrhenius also developed the...

Theoretical physicist Richard Phillips Feynman greatly simplified the way in which the interactions of particles could be described through his introduction of the diagrams that now bear his name (Feynman diagrams) and was a co-recipient...

Robert Andrews Millikan was a prominent American physicist who made lasting contributions to both pure science and science education. He is particularly well known for his highly accurate determination of the charge of an electron via...

This PBS site offers videos and activities are hands-on challenges that focus on the engineering design process. They use simple materials, allow for multiple solutions, and are ideal for ages 9-12.

Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature.
