How Modern Light Bulbs Work

Mr. Andersen contrasts series and parallel electrical circuits. A simulation is used to visualize electron flow through both circuit types.

Which Houseplants Are Toxic to Kids And Pets

Howcast - Learn the difference between LED and CFL lightbulbs in this Howcast video featuring Alegre of Green and Greener.

Compact fluorescent light bulbs, or CFLs, use about 75% less energy, give off 90% less heat, and last up to ten times longer than old-fashioned incandescents. Changing over is as easy as... well, screwing in a light bulb.

Many ways to help the environment are costly, but using less electricity is one measure that will save you money.

If you want a beautiful garden in the spring, you have to start planting your bulbs in the fall.

Daffodils -- also known as Narcissus -- are woodland plants that make a beautiful addition to any garden.

Pupil outcome: I can plan to investigate variables that may affect the brightness of a bulb in an electric circuit. Key learning points: - A variable is any one thing in an investigation which could be changed. - Adding other components...

An incandescent bulb mainly consists of two parts—the bulb and the filament. The bulb is generally made of glass, within which is a vacuum. The filament inside the bulb is where the actual light is produced. It is made of a long and...

Some plants don't need both a male and female to reproduce - they can do it alone. Which plants can do this and how do they manage it? Biology - Plants - Learning Points. Plants use a variety of methods to reproduce. Methods include...

Dr. Forrester discusses parallel circuits and complex circuits. She reads a complex circuit diagram by identifying how electricity is transported within the pathways.

Miss Palomine enters the classroom and finds it dark. She turns on the desk lamp. This begins the discussion of Thomas Edison, the light bulb, and the various uses of electricity in modern life.

This video is answering the question of does changing lightbulbs affect energy usage.

This problem is about what happens to the brightness of two light bulbs when you place a wire across the circuit which essential shorts out one of the two light bulbs.

Here we test the money saving advice given on a package of energy efficient light bulbs. We also define KiloWatt Hour; a term that often confuses students. Oh, we also determine the resistance of the light bulbs, ya know, just because...
