Look Ma, I’m a Battery

[sc:commonscripts] Look Ma, I'm a Battery In a nutshell, a battery uses a chemical reaction to produce an electrical current.  In this experiment, we will create an electric current using nothing more than our own bodies (Reeko promises this won't hurt.... much). Mount the copper and aluminum metal plates to two separate pieces of wood. Connect one plate to one of the DC microammeter's terminals using an alligator clip and the hookup wire.  Connect the other plate to the second terminal.  A DC microammeter, which is an instrument that measures the electric current in a circuit, can be purchased from your local Radio Shack, electronics hobbyist, or auto store. Now place one hand on each plate. You should see an electric current generated on the meter.  If you don't see a

Lemon battery experiment – if life gives you lemons, make a battery!

Lemon battery Batteries store chemical energy that can be transmitted as electrical energy through various components in a circuit. You can think of the circuit as the path the electrons (electricity) take. The path has to have no breaks in it and it much be a path made of a material that will allow the electrons to flow (e.g. most metals although some are better conductors than others). Batteries, such as the one we are about to build, have electrodes, or the connection points on the battery. The anode is the electrode at which electrons leave the cell and oxidation occurs, and the cathode is the electrode at which electrons enter the cell and reduction occurs. In our battery, the lemon juice acts as the electrolyte which
