- Grape tomato – 0.2v
- Onion – 0.3v
- Grapefruit – 0.4v
- Apple – 0.25v
- The deeper the two metals went into the fruit, the stronger the voltage was
- When the two metals went into two different fruits, the combined voltage was higher
- If the fruit had more acid, the greater the electric charge would be
Purpose: To know what fruit will have the greatest voltage
Hypothesis: When the grape tomato is attached to the voltmeter it will produce the most electric voltage
Materials: Fruits, voltmeter, 2 wires, 2 different metals (copper & zinc), knife
- Cut the fruit
- Put in the 2 metals into the fruit
- Attach one end of the 2 wires to the 2 metals in the fruit
- Attach other end of the 2 wires onto voltmeter
- Record results
- Repeat procedure with other fruits and record results
- Mix and match some fruits together (i.e. grapefruit and lemon) to create greatest voltage

Debrief: The quality of my post and process could’ve been better, I did well on describing my challenge but I could’ve worked on the Dream process more.
