Transcript of Science Fair

1. Retrieve materials.
2. Be careful of sharp objects.
3. Get your twist ties and strip out the ends of them. One end must be stripped out 1.5 inches and the other end half an inch.
4. Using the longer end of the stripped twist tie, wrap it around the nail four times. Do this for all nails.
5. Put your nail about a half inch into whatever fruit you are using. Do this to two of your fruits
6. Insert the other end of both twist ties into your next fruit. Put it approximately 1 inch apart.
7. Let your fruits sit like this for at least 15 minutes. The longer you leave it sitting, the better the charge for your iPod will be.
8. Insert your USB cord into your iPod and using the other side of the cord that is supposed to be inserted into a computer, put it in the 1 inch space between the two twist ties.
9. Watch your iPod turn on By: Erin Ohta and Jasmine Davis Charging your iPod with
Fruits What combination of fruits (that fell off a tree) provides the most energy to turn on an iPod the fastest? Problem You're probably wondering, how does this work?
Well... If we use a lemon, orange, and a banana, then it will produce the most energy, because lemons and oranges have the highest amount of citric acid which causes an electrical circuit. Hypothesis Background Info. This is how it works, the acidic juice of a fruit mixes with the two metals that get stuck into the fruits. The fruit juice acts like an electrolyte, the electrolyte is a conductive liquid so the acidic juice is a substance. + = A chemical reaction takes place between the metals and the citrus fruit which creates voltage and pushes the electrons through the circuit. A closed circuit is when electrons flow from the power source and back again with no breaks. + Citations: Materials 1. 2 iPods
2. 2 iPod charger(USB cord)
3. Fruits(like lemons, oranges, bananas, etc. Have at least 3 of each)
4. 4 Nails
5. 4 Twist ties
