I want to know what pennies are exactly made of, and what exactly the materials they use, and if possible, why are these materials used?

You didn't say what grade you are in, Ana, but your question has been asked and answered again and again on this site. And part of the reason for your assignment is so you will develop research skills (which means finding the answer rather than asking someone else to find it for you).

Pennies are made of zinc, plated with copper. They used to be solid copper, but copper got expensive enough that a copper penny would be worth more melted down than as a coin.
