Through research, the researchers found out that acid is actually pretty weak by itself but when the zinc nails are mixed with the acids, it creates a chemical reaction. The copper pennies complete the circuit. That is the reason why the researchers chose the specific materials to experiment with. A lemon has 5% more citric acid, which is why the yellow fruit is so sour. An orange is also a member of the citrus family, as an orange colored fruit. Even though an orange is a part of the citrus family, it doesn't have as much acid as the lemon does. When the researchers place the two metals, copper and zinc, into the fruit, they help the electrons to start to flow inside of the fruit. It is the electrons flowing from metal to metal through the acids in the citrus fruits that causes an electrical current. Acid doesn't actually produce electricity alone; the weak acid turns into an electrolyte. With the help of the zinc and copper, the ions inside of the electrolyte let the electricity flow throughout the acid. The fruit batteries can create electricity to power different objects. The energy doesn't come from the acidity, but the acidity paired with the two dissimilar metals. The energy that is produced can be extracted using different wires, eventually leading to the charger that will be used for the researchers' experiment. .
To power and iPhone, 5 volts are needed. .
Hypothesis: If we made batteries out of the lemons and oranges, then the lemons will produce the most energy to my phone because they have a higher acidity level/PH level.
Materials.
• 5-6 oranges.
• 5-6 lemons.

• iPhone.
Method:.
1. First, the researchers are going to cut off the male "USB-A plug.".
2. Then, the researchers will strip off the outer cable sheath and cut off the green and white wires.
3. Then, the researchers will strip the red and black wire.
