Kid's learn about the uses electricity. Where is it used and how does it help us in our daily lives.

[Free Registration/Login Required] Students can use this Flipchart to learn and apply Ohm's law to basic circuitry problems. Students are introduced to the relationship among voltage, current, and resistance, and then apply their newly...

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...

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 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....

This lesson 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, learners learn...

Use your knowledge of physics concepts like electricity, reflection, magnetism, etc. to complete interactive online puzzles.

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.

Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity. Java required.

Read about the amazing development of plant-powered lamps that are bringing electricity to a village in remote Peru. Includes video.

This is a sample lesson on electromagnetism. It includes animated diagrams, interactive exercises, an audio option for reading the text, and comprehension questions throughout where students can type their answers or pick from...

Learners are given a history of electricity and its development into the modern age lifeline upon which we so depend. The methods of power generation are introduced, and further discussion of each technology's pros and cons follows.

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...

Explore the world of vectors, by finding answers to questions like what are vectors, what are scalars, what is the difference between scalar and vectors, the magnitude of a vector, operations on vectors, and properties of a vector.

A teacher unit which includes several hands-on activities about types of magnets, magnetism, and electrostatics. An activity designed to suit all grade levels. Many parts of the activity would be easily adaptable as a student project.

This lab is designed to have students look at the deflection of a cathode ray beam using magnetic fields and electric fields.

French physician Guillaume Benjamin Amand Duchenne invented a device that electrically stimulates muscles. The apparatus gave him new insight into neuromuscular disorders, earned him the epitaph of "father of electrotherapeutics," and...

Learn how electric charges work and about Coulomb's Law, which is used to calculate the strength of an electric force.

Fire lighted the night for many centuries. Then came Sir Humphry Davy and the birth of the arc lamp, an invention built upon in the years that followed by many.

The Earth, the moon, the stars and just about everything in between has a magnetic field, and scientists use magnetometers when they need to know the strength of those fields.

Acoustics, variable resistance and allegations of foul play contribute to the exciting story of the invention of the telephone.

As more and more American households acquired telephones, the pressure was on to create a better cable to accommodate the increasing demand. Engineers Lloyd Espenschied and Herman Affel answered the call.

Read this brief article to gain an understanding of the principle of electromagnetism, how electricity is generated, and the problem with fossil fuels.

Explains electromagnetism, the difference between a permanent magnet and an electromagnet, uses of electromagnetism, and steps for making a simple electromagnet.
