How to build your own electric motor
This home page features award-winning, easy-to-build, and inexpensive electric motors. If you are looking for a simple science project, or if you wish to learn about electricity, magnetism, and electric motors, this web site has it all! Including assembly instructions, a section devoted to how these motors work, and I even provide all parts necessary to build them! The reed switch motor is the e

How to create an electrostatic charge using a handheld electrophorus
A hand-held electrophorus can produce significant amounts of charge conveniently and repeatedly. It is operated by first frictionally charging a flat insulating plate called a "cake". In Volta's day, the cake was made of shellac/resin mixtures or a carnauba wax film deposited on glass. Nowadays, excellent substitutes are available. TeflonTM, though a bit expensive, is a good choice because it is a

How to generate enough static electricity to create sparks
In this experiment we'll create an object called a electrophorus (greek word for charge carrier). Using the materials listed above, we'll charge the object and then discharge it creating a snap, a little electrical shock, and a bright spark. If you're afraid of a little electrical shock then get Dad to discharge the object for you. And for grins, don't tell Dad beforehand about the resulting sp

How to make a battery using the human body!
In a nutshell, a battery (a device that produces electricity by means of chemical action. A battery consists of one or more units called electric cells. Each cell has all the chemicals and parts needed to produce an electric current.) uses a chemical reaction to produce an electrical current (the movement or flow of electric charges). In this experiment, we will create an electric current using n

How to make a crystal radio detector
If you appreciate ingenuity, simplicity, and like instant gratification from your radio projects, then you ought to spend a few minutes building your own foxhole radio. Foxhole radios were built by GIs in World War II from materials they had easy access to in the field. They usually consist of just a coil and a detector. They use a point detector, the chief component being an ordinary razo

How to make your own telegraph machine.
You can make your own telegraph for sending secret messages to a friend. This project may require a trip to the store, some patience, and maybe a bit of help, but it's well worth it. After connecting all your wires and buzzers, you'll be able to “talk by lightning” (as telegraphy was once called).

Hydropower versus wind power
This science fair project was performed to compare the efficiency of hydro-electric generated power and wind generated power.

Making lightning in a pan!
Lightning is beautiful, dangerous, and mysterious. The same brilliant flashes that inspire poetry and paintings can cause city-wide power outages and raging forest fires. Try this easy experiment to make your own miniature version of a lightning bolt.

Soil fertility and conductivity
This science fair project was performed to observe the relationship between soil type and soil conductivity. The testing was done using sand, clay, loam and loam mixed with fertilizer.

The effect of different Electrodes and Electrolytes on voltage
The purpose of this experiment is to find out what combination of electrodes and electrolytes gives out the highest voltage. This study is important for companies who produce batteries so that they will know which materials to use to yield the highest amount of electrical energy.
