Title: Battery Experiment

Description: This experiment is about changing the size of copper in the battery that uses aluminum and copper to create electricity. The size of copper was changed 5 times in a certain pattern to see how it affects the voltage and current of the battery. The results of the experiment was that the size of copper does not affect the voltage and current of the battery significantly. The size of aluminum was also changed to see how it would affect he battery but the results were the same.

Introduction:
 * Purpose- The main purpose of this experiment is to see how the size of the copper in the battery affects the voltage and current of it.
 * Independent variable- Size of copper
 * Expectation- We expected that the bigger the copper is, the more voltage and current there would be. We expected this because there would be more metal to conduct electricity.

Materials

 * 1 copper for each of the different sizes
 * 1 aluminum (4x4)
 * Voltmeter
 * Wire
 * Beaker

Procedure
1. Cut 5 pieces of copper and cut them into 2x2, 3x3,4x4,5x55,6x6 cm2 each 2. Get aluminum and cut it into 4x4cm2 3. Get a beaker and fill it with 400ml of water 4. Connect one sheet of copper and one sheet of iron with different wires 5. Place the metals on opposite sides of the beaker filled with water 6. Connect the two wires with the voltmeter 7. Measure and record voltage and current 8. Repeat this 4 times while using different size copper ( The amount of water and the size of iron stays the same)
