5. Chemical Energy is Needed o Batteries Batteries work by using multiple chemicals that interact with one another to create electrical energy. The most widely used type of battery is a zinc-copper battery which uses the chemicals zinc and copper, zinc being the negative side and copper being the positive side. When a wire is a connected to both ends, the acid inside the battery is excited and breaks down some of the zinc. The electrons from that zinc are then free to travel along the wire to the copper side where electricity is conducted and then able to flow into the device that the

7. Chemical Energy is Needed o Food Food is a form of chemical energy. When plants create sugar through photosynthesis, they provide animals such as bees, rabbits, birds, and insects with a steady food source. Those creatures use some of the energy that they absorbed to function while the rest is stored for later use. By storing extra energy, however, they provide a steady food source for other animals such as foxes, wolves, dogs, and cats. Likewise, those animals store some of the energy they absorb and are eventually eaten by even larger animals such as bears, lions, and humans. The entire food chain is based on chemical energy.

8. Conclusion The energy transformation that took place from the alligator clips to the apple was electrical energy to mechanical energy. This happened because, electrical energy from the alligator clips from the apple made the meter move turning the energy to mechanical. The variables that effected the output of the apple battery were the variation and size of the metals.
