Students do work by lifting a known mass over a period of time. The mass and measured distance and time is used to calculate force, work, energy and power in metric units. The students' power is then compared to horse power and the power...

Find out how waste can be recycled and what you can do to aid recycling efforts in your community. With complete overviews of the types of materials that can be recycled: e-waste, paper and cardboard, metals, glass, plastics,...

Students make a simple conductivity tester using a battery and light bulb. They learn the difference between conductors and insulators of electrical energy as they test a variety of materials for their ability to conduct electricity.

Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.

An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view....

Uncountable times every day "with the merest flick of a finger"each one of us calls on electricity to do our bidding. What would your life be like without electricity? Students begin learning about electricity with an introduction to the...

The invention of the light bulb quickly created the need to track people's electricity usage. In 1872, Samuel Gardiner built the first simple power meter: a lamp with an attached clock that recorded the time the light was on.

Short descriptions of important technological innovations produced in America and the date of their introduction.

This site from Enchanted Learning presents several brief overviews of major early nineteenth century inventors and their inventions. The information is accessible by clicking on the corresponding link.

Did you ever wonder who invented something, and when it was invented? Go to this interactive timeline that highlights inventors/inventions from 1750-1990. Click on the topic to read a brief paragraph about that invention.

Did you know your brain has enough power to illuminate a light bulb? Featured at this fun site are 20 amazing facts you can learn about your brain.

Our pipes leak, air drafts push through our windows and walls, light bulbs create more heat than light, and every appliance we have stays plugged in all day long. Of course its our parents who pay the bills, so it doesn't matter. This is...

In this exploration activity, students compare the difference between series circuits and parallel circuits using wire, light bulbs, and D batteries.

This activity introduces students to the concepts of electrical current and open and closed circuits. Students will act out open and closed circuits as a whole class with some students acting as the "motors" or "light bulbs."

You've probably heard that carbon dioxide is warming the Earth. But how exactly is it doing it? Lieven Scheire uses a rainbow, a light bulb and a bit of quantum physics to describe the science behind global warming. [5:01]

Young scholars took what they had learned and created a matching game (simple circuit board) for others to test their knowledge about energy. The matching game illuminates a light bulb, when the correct matching pairs are selected.

In this simulation a battery will be used to charge a capacitor. The capacitor will then be used to operate a light bulb until the capacitor is discharged.

The core of this instructional activity is simple circuits and the differences between parallel and series circuit design. Young scholars perform experiments to test the differences between the two circuit designs using low voltage light...

Meet the inventor of the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb, Thomas Edison.

Compared to incandescent lamps, fluorescent lamps last longer, require less energy and produce less heat, advantages resulting from the different way in which they generate light.

[Free Registration/Login Required] In this interactive you will drag each gas bulb into the red circle to excite them and see their emission spectrum. You will need a sign-in to access this media, but it will be worth your time!

This site has a biography of the man who helped develop the light bulb.

The biography of the fascinating African-American inventor, Lewis Latimer. In addition to finding out about his development of the carbon filament for the incandescent lamp, you can read about his expertise in patent law, his association...
