I want to find out more about electricity
AC/DC: What’s the Difference?
To find out more about alternating and direct current, what exactly an electric current is, and two ways that the currents can be produced, check out the interactive illustrations on these pages.
Electricity and Magnetism
This module will introduce you to many of the basic concepts involved with Electricity and Magnetism. We will introduce you to static charge, moving charge, voltage, resistance, and current. Magnetism and how it relates to electricity will also be presented.
How Batteries Work
Learn some fun facts about batteries and flashlights … how they work, their history, how to take care of them … and visit our Science Center to experiment with our do-it-yourself science projects. From the Energizer company.
The Lemon Battery
Did you know you can make electricity without a battery or a generator? You can make a small amount of electricity with a lemon. Note: wash the coins thoroughly first!
All about the huge Van de Graaff Generator at the Museum of Science in Boston. Indoor bolts produced by the world’s largest air-insulated Van de Graaff generator spark exciting explorations of lightning, conductors, insulators, electricity, magnetism, and storm safety.
Molecular Expressions: Electricity and Magnetism
These interactive Java tutorials will help you understand how electrical devices work.
Manitoba Hydro has a nice site explaining the production of electricity. Plenty of illustrations showing how hydro power is generated. They seem a bit negative and dated about alternative energy sources that they don’t produce, so a little head’s up there.
What Is Electricity?
Where does it come from? How does it work? Before we understand all that, we need to know a little bit about atoms and their structure.
Where do we get energy to run our house?
Edison’s Miracle of Light
1879: Edison invents the carbon-filament lamp and a direct-current generator for incandescent electric lighting. A New Year’s Eve demonstration of his system is held for the public at Menlo Park. The site gives Edison the credit for trying to harness Niagra Falls, but this was really the idea of Tesla. You can read about Tesla and Westinghouse’s project on another PBS site.
Roofus is a dog who has made his doghouse “energy smart.” You can test your home and make it use solar energy, too. From the Energy Information Administration.
From the US Energy Information Administration. A full set of lessons for learning about energy. Includes a games section.
Experiments from the Charles Edison Fund
You can become an energy waste-watcher! Once you know what to look for, you can make valuable energy-saving suggestions to your friends and your parents.
How Nuclear Power Works
In nuclear power plants, neutrons collide with uranium atoms, splitting them. This split releases neutrons from the uranium that in turn collide with other atoms, causing a chain reaction. This chain reaction is controlled with “control rods” that absorb neutrons. From the Union of Concerned Scientists.
Tesla: Master of Lightning
Learn about his life and legacy. Did you know that he invented the remote control?
Virtual Power Plant Tour
Another coal-burning power plant tour, but with Quicktime and Shockwave multimedia features. Best with fast connection.
I want to find out more about electronics
Without a thorough grasp of basic electronics you will never fully understand the later and much more complicated electronics tutorials. As a suggestion start by reviewing “starting out in basic electronics” followed by some radio electronics terminology.
Basic Electronics Course
You are at the best, free online “Basic Electronics Course”. Just read the brief blocks of text, view the videos, and check out some of the screened internet links. This is the easiest, fastest way to learn basic electronics. No sign-up requirements and it is free.
Here are some neat circuits you might want to try to build.
From Rohm Semiconductors: an electronics vocabulary glossary. What is a transistor? What is a diode? What are SiC power devices? What are LEDs? What is a Photointerrupter? What is a resistor? What is Tantalum Capacitor? What is a D/A converter? What is an A/D converter? What are opamps? What is Semiconductor Memory? What is a DC/DC converter? What is a motor? What is SPICE?
Learn About Electronics
Did you know that there are over 500 pages of electronics know-how available to download and print, in 30 different Modules, just click the “Prefer Paper?” pdf logo on any module, and its yours to print and keep.
I want to build a motor
How to make a BristleBot
Evil Mad Scientist Laboratories shows you how to make a robotic toothbrush using a watch battery, foam tape, a vibration motor and some wire, solder and soldering iron. I’m assuming you have a toothbrush from your dentist.
Beakman’s Electric Motor
I saw this on the TV show Beakman’s World and I was very impressed that you could actually build a working electric motor with so few parts.
Build an Electric motor in 10 Minutes
The motor is simply a battery, a magnet, and a small coil of wire you make yourself. There is a secret to making it (which I will of course share with you) which is at the same time clever and delightfully simple.
Simple Electrostatic Motor
You can build this simple electrostatic motor from 2-liter soda bottles and aluminum foil. Its construction does not require access to a machine shop. It draws a fraction of a microamp during operation, and can run at unexpectedly high speeds (1000 RPM!).
What is Static Electricity?
Start your own electric flea circus! In this Exploratorium Snack, static electricity makes electric “fleas” jump up and down.
There are several things which interfere with our understanding of “Static Electricity.” Most demonstrations incorrectly focus on friction. Also, the nature of matter and the fundamental reasons for charge conservation are usually ignored. By William J. Beaty.
Static Electricity Page
Homeschooling dad, Bill B, has page after page of experiments you can do to help understand static electricity and its uses.
What is Static Electricity?
You walk across the rug, reach for the doorknob and……….ZAP!!! You get a shock. What was that???!!!
