Copper and Zinc Elements:
Fruit Battery Electrodes

Iron, Lead, Aluminum, Brass, Nickel Strips:
Thermal/Electrical Conductivity Experiments

Copper and zinc element strips can be used as electrodes to make lemon and other types of fruit batteries or a potato battery. Fruit juices are highly acidic and because the elements have a large surface area, they will generate enough current to run a small light bulb.

These as well as the iron, aluminum and nickel elements can be used in thermal conductivity or electrical conductivity experiments.

The iron, copper and aluminum strips each behave differently when used with magnets. Try sliding a rare earth disk magnet rapidly along a copper or aluminum strip & feel what happens.

All strips are 19mm wide x 130mm long (3/4" x 5"); metals are <1mm thick; carbon: ~4mm.

Note: Brass is an alloy of copper and tin.
