Y6 Electricity Lesson 1

1. What is an atom?

• Electricity flowing around a circuit.

• The smallest part of a chemical element.

• A nucleus.

• I'm not sure.

Answer explanation

An atom is defined as the smallest part of a chemical element, consisting of a nucleus surrounded by electrons. This makes the second answer choice the correct one, as it accurately describes what an atom is.

Label the atom

c

b

a

proton

electron

neutron

Protons are negatively charged (-)

• True

• False

Answer explanation

Protons are positively charged, not negatively. Therefore, the statement that protons are negatively charged is false.

What would you find in the nucleus of an atom?

• Electrons (-)

• Neutrons

• Protons (+)

• I'm not sure

Answer explanation

In the nucleus of an atom, you will find protons, which are positively charged, and neutrons, which have no charge. Electrons are located outside the nucleus.

What orbits the nucleus of an atom?

• Electrons (-)

• Neutrons

• Protons (+)

• I'm not sure

Answer explanation

Electrons, which have a negative charge, orbit the nucleus of an atom. Neutrons and protons are found within the nucleus itself, while electrons are the particles that move around it.

What is potential difference?

• The energy a power source gives to move electrons around the circuit.

• The flow of electrons around the circuit.

• I'm not sure.

Answer explanation

Potential difference refers to the energy provided by a power source to move electrons through a circuit. It is not about the flow of electrons itself, but the energy that enables that flow.

Which battery gives the most energy to electrons?

• A - because it is smaller

• B - because it is bigger

• They both give the same energy to electrons

• I'm not sure

Answer explanation

Both batteries provide the same energy to electrons, as energy output is determined by voltage and chemical composition, not size. Therefore, the correct answer is that they both give the same energy to electrons.

Electricity comes out of both ends of a battery.

• True

• False

Answer explanation

The statement is false because electricity flows out of one terminal (the positive) and returns through the other terminal (the negative) of a battery, not both ends simultaneously.

Electricity flows from...

• (+) terminal to (-) terminal

• (-) terminal to (+) terminal

• both ways

Answer explanation

Electricity flows from the positive (+) terminal to the negative (-) terminal. This is due to the convention established in electrical engineering, where current direction is defined as the flow of positive charge.
