100

This is a liquid that allows electricity to travel

What is an electrolyte?

100

This is what is created when an unbroken loop allows electric current to flow in a circular pattern.

What is a circuit?

100
We used this fruit to make a battery in our lab last week.

What are lemons?

100

These are positively charged particles.

What are protons?

100

We used this type of metal as the anode in our circuit.

What is a zinc/galvanized nail?

200

Lemons work as a battery for this reason.

They contain citric acid, which acts as an electrolyte.

200

This type of circuit is complete and allows electricity to flow freely.

What is a closed circuit?

200
Our lemon battery was used to power this kind of device.

What is an LED?

200

These are negatively charged particles.

What are electrons?

200

We used this type of metal as the cathode in our circuit.

What is a copper penny?

300

This is what makes a lemon sour.

What is a high amount of citric acid?

300

This type of circuit is broken and stops the flow of electricity.

What is an open circuit?

300

This vegetable was also used to help create our battery.

What are sweet potatoes.

300

These are charged particles inside a liquid.

What are ions?

300

This metal was giving away electrons in our lemon battery.

What is zinc?

400

This is the amount of voltage that you might get from a single lemon in a lemon battery.

What is approximately 1 volt?

400

Doing this in our lemon battery made the LED glow brighter.

What is increasing the number of lemons?

400

We also needed these two kinds of metal to produce our lemon battery.

What are zinc and copper?

400
This is a liquid that conducts electricity by acting as a medium for ions to move between electrodes.

What is an electrolyte?

400

This metal is what was accepting electrons in our lemon battery.

What is copper?

500

These fruits contains the highest amount of citric acid.

What are lemons and limes.

500

This is what happens when the zinc and copper touch inside of a lemon battery.

What is a short circuit.

500

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.

500
A lemon battery is this type of battery.

An electrochemical or electrolytic battery.

500

This is the reason metals are good conductors of electricity.

Their atomic structure allows for easy flow of electrons.
