Hear from deep space. Pupils learn how satellites transfer information back to Earth. They learn about three different ways to modulate radio waves and how a satellite sends information with only 0s and 1s. Using sound, class members...

Explore the science of space exploration. Pupils consider technological advances in propulsion, communication, power, navigation, and imaging. They select one of these areas and create a timeline of historical progress that contributed...

The report provides an overview of the electricity consumption in households in 2001. End-use (lighting, appliances, heating) data is presented in written, graph and table form. Background on efficiency standards and regional factors...

A guided activity for students to compare incandescent and CFL light bulbs observing the production of heat and light.

Physics students find out how to effectively define and clarify kinetic and potential energy.

Read this illustrated article to help you understand the concept of work in regards to the transfer of mechanical energy.

This Kahn Academy tutorial helps students understand the principles of conservation of energy and mass. [10 min, 6 sec]

This article discusses the properties of electromagnetic radiation and photons.

A very simple electrical resistance thermometer is described that can be built, calibrated and tested in a school laboratory at virtually no cost. With it, flames, focused sunlight and other high temperature sources can be probed. The...

Learn why the Sun keeps us healthy, and also, learn how the Sun can harm our skin, eyes, and immune system. Read about the dangers associated with the Sun's ultraviolet rays, and read tips to help you stay safe when outside in the summer...

This essay from the NOVA Web site explores the impact Einstein made on physics and most everything we know about the cosmos.

Students learn about the conservation of energy, aspects that affect energy in a system such as pressure and temperature, and to gain a better understanding of concepts such as entropy.

Find out about Steven Chu who is known for his research in cooling and trapping of atoms with laser light, which won him the Nobel Prize in Physics.

Sunburn isn't just painful, it's dangerous. Learn about the connection between sun exposure and skin cancer, and learn how treat sunburn. Also, learn how to prevent getting sunburn with three simple tips. Use the links on this page to...

If you don't know that the incandescent light was a failure before it was a success, it's easy to write off some modern energy innovations like solar panels because they haven't hit the big time fast enough. Worse, the fairy-tale view 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...

Fusion is the process at the core of our Sun. What we see as light and feel as warmth is the result of a fusion reaction: hydrogen nuclei collide, fuse into heavier helium atoms and release tremendous amounts of energy in the process.

Explaining the experiments on the photoelectric effect. How these experiments led to the idea of light behaving as a particle of energy called a photon.
