In this physical science lab, learners will investigate ways to control an electromagnet, how adding coils of wire can change the magnet, and the differences between an electromagnet and a bar magnet. Students will explain in their...

After building a simple electric motor from a kit, with this experiment you can explore how voltage affects motor speed. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

A good site about the Surveyor missions to the moon, which includes findings from the experiments that were aboard the lander.

Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. First, students move a coil of wire near a magnet and observe the voltage that results. They then experiment with moving the wire, magnet,...

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...

Article explains the experiments on the photoelectric effect and how these experiments led to the idea of light behaving as a particle of energy called a photon.

Build your own windmill and see how the wind can be converted into energy to produce electricity. This science fair project should help you understand the use of wind as a source of alternative energy. The Science Buddies project ideas...

In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

In this experiment, you will measure the speed of light using a microwave oven, some egg white, and a ruler. This short project proves to be an extremely interesting choice for a science lab, with pictures for illustration, and thorough...

Take a look at light with these three easy experiments

An easy experiment through which students learn about light rays and the electromagnetic spectrum. Requires a TV, its remote, and a hand-held, flat mirror.

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...

In this computer-based virtual lab, students will learn about the layers of Earth's atmosphere by launching virtual balloons to collect temperature and pressure data at various altitudes. Given a limited number of balloon flights,...

In addition to overviewing Compton's (1892-1962 CE) studies in x-rays, this article includes information on Compton's published works, his education, and personal life.

Visit this site for an interactive tour of the atom and all aspects of particle physics. View the animations available with almost every description on this site. A great place for the fundamentals of particles and forces including a...

Hans Christian Orsted's accidental discovery that an electrical current moves a compass needle rocks the scientific world; a spate of experiments follows, immediately leading to the first electromagnet and electric motor.

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

What colors do you see in a bubble? Why do you see colors in a bubble? Use this site to find out the answer to these questions with this easy experiment.

A discovery by Hans Christian Orsted forever changed the way scientists think about electricity and magnetism. While preparing to perform an experiment during a lecture at the University of Copenhagen, he found that the magnetized needle...

Joseph Henry was an American scientist who pioneered the construction of strong, practical electromagnets and built one of the first electromagnetic motors. During his experiments with electromagnetism, Henry discovered the property of...

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity to light an LED. No battery or complex circuitry is required. The device can form the basis of a range of...

At this site from the Nobel e-Museum, you can read about the scientific work of Lord Rayleigh (1842-1919 CE). This article includes information on his education and experiments with light and sound waves.

This is a short demonstration to learn about the different types of forces.

Here's a really simple demonstration of a fluoroscope. There are links to more information about the uses of X-rays as well.
