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.

Students will explore the basics of dc circuits analyzing the light from light bulbs when connected in series and parallel circuits. Ohm's Law and the equation for power dissipated by a circuit will be the primary equations used. Using...

Students 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.

[Free Registration/Login Required] Learn about how capacitors are used in circuits to create transient events such as the flash of a light bulb using this interactive simulation. A PDF worksheet and a video tutorial are also available....

Conserve energy at home with Compact Fluorescent Lamps or CFL light bulbs.

The core of this lesson is simple circuits and the differences between parallel and series circuit design. Students perform experiments to test the differences between the two circuit designs using low voltage light bulbs.

Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand...

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...

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...

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...

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,...

[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!

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.

In this activity, students' will explore how the tilt of the earth's axis results in different amounts of solar radiation at different times of the year, causing seasons. They will simulate the earth's warming using a light bulb that...
