Fruit Facts
This is a liquid that allows electricity to travel
What is an electrolyte?
This is what is created when an unbroken loop allows electric current to flow in a circular pattern.
What is a circuit?
What are lemons?
These are positively charged particles.
What are protons?
We used this type of metal as the anode in our circuit.
What is a zinc/galvanized nail?
Lemons work as a battery for this reason.
They contain citric acid, which acts as an electrolyte.
This type of circuit is complete and allows electricity to flow freely.
What is a closed circuit?
What is an LED?
These are negatively charged particles.
What are electrons?
We used this type of metal as the cathode in our circuit.
What is a copper penny?
This is what makes a lemon sour.
What is a high amount of citric acid?
This type of circuit is broken and stops the flow of electricity.
What is an open circuit?
This vegetable was also used to help create our battery.
What are sweet potatoes.
These are charged particles inside a liquid.
What are ions?
This metal was giving away electrons in our lemon battery.
What is zinc?
This is the amount of voltage that you might get from a single lemon in a lemon battery.
What is approximately 1 volt?
Doing this in our lemon battery made the LED glow brighter.
What is increasing the number of lemons?
We also needed these two kinds of metal to produce our lemon battery.
What are zinc and copper?
What is an electrolyte?
This metal is what was accepting electrons in our lemon battery.
What is copper?
These fruits contains the highest amount of citric acid.
What are lemons and limes.
This is what happens when the zinc and copper touch inside of a lemon battery.
What is a short circuit.
This will cause our lemon battery to fail, even though we have enough lemons and it is wired correctly.
The zinc (nail) and copper (penny) are touching inside the fruit or one of the lemons are too dry inside.
An electrochemical or electrolytic battery.
This is the reason metals are good conductors of electricity.
Their atomic structure allows for easy flow of electrons.
