34 Electricity science fair projects

Hydroelectric facilities are built at the base of dams to take advantage of the high pressure of the water at the bottom of a reservoir. The water pressure is funneled through a tunnel through the dam called a penstock. The water then is focussed on the blades of a turbine. Water pressure of the water turns the turbine, and the turbine turns a generator making electricity. This simple experiment will show...

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 spark and...

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 nothing...

There are a number of science museum exhibits which require many tens of amperes of electric current in a thick cable to generate strong magnetism. One example is a raft of compasses with a 200-amp cable running through the center of the raft. Or, three 100-amp cables with three-phase AC powering them, where the resulting field rotates and can spin a conductive object by induction. Rather than...
