Write about some of its' common uses.

Obviously in electrical wires, since it is a good conductor of electricity.
As a component in the alloy brass (copper and zinc) and in the alloy bronze (copper and tin).
It is great (if you can afford it) as gutters and roofs. You often see it on church roofs and some public building such as the Statue of Liberty.
It is often used mixed in some metals for rings (jewelery), thus the green finger.
It makes a great poison in lakes, ponds, aquariums, and the such, since algae and some other aquatic plants are killed by it. Finally, it looks cool in fireworks (green colors).

Get an "A".
