Electricity

Front

What is electricity? Is it the magical conversion of light into energy, as Noah suggests? Could it be the movement of atoms in a closed path, as Anika thinks? Or is it the flow of water through a circuit, as Emma believes? Or is it the flow of tiny particles called electrons, as they read in a book?

Back

The flow of tiny particles called electrons.

What is the purpose of an electrical circuit in a robot? Options: To generate electricity for their robot, To store electricity for later use in their robot, To control the flow of electrons in their robot, To convert electricity into other forms of energy in their robot

Back

To control the flow of electrons in their robot

Who is correct in the debate about DC and AC currents? Maya says that DC (Direct Current) is used in batteries, while AC (Alternating Current) is used in power lines. Mason argues that DC flows back and forth, while AC flows in one direction. James believes that DC has higher voltage, while AC has higher amperage. You remember from your science class that DC flows in one direction, while AC flows back and forth.

What is the purpose of the battery that Lily, Priya, and Aiden found? Is it to convert electricity into other forms of energy? Could it be to store electricity? Maybe it's to control the flow of electrons? Or is it to generate electricity?

Back

It could be to store electricity.

What is the main source of energy for solar cells?

Back

Sunlight

Noah, Liam, and Lily are having a debate. Noah thinks a photovoltaic cell is used to store electricity, Liam believes it's used to control the flow of electrons, and Lily argues that it's used to convert light into electricity. Who is correct?

Back

Lily - To convert light into electricity

What is the function of a generator? Options: Is it to store electricity like a giant battery? Or does it convert electricity into other forms of energy? Maybe it controls the flow of electrons? Or does it actually generate electricity?

Back

It actually generates electricity.

In the game 'Electron Rush', what role does the voltage play in their electrical circuit?

Back

It acts like a coach, providing the pressure for electrons to rush and score.
