What do we call electricity that does not flow?
Static electricity
Does this atom have a positive charge, a negative charge, or is it neutral?
It's neutral (It has the same number of protons and eletrons).
What are the three particles in the atom? (AKA: subatomic particles)
Protons, neutrons, and electrons
Which particle of the atom is neutral / hasn't got a charge?
The neutrons
TRUE or FALSE: Objects with opposite charges attract each other.
TRUE: An object with a negative charge will attract an object with a positive charge.
What type of electricity is this? (Static electricity or electrical current?)
Electrical current
TRUE OR FALSE: Porcelain is an electrical conductor.
FALSE: Porcelain is an electrical insulator.
TRUE or FALSE: Open circuits have electrical current.
FALSE: Electrical currents can't flow in an open circuit.
What do we call materials that allow electrons to flow without resistance?
Electrical conductors
What unit is all matter made up of?
Atoms
TRUE or FALSE: Objects with the same electrical charges attract each other.
FALSE: Objects with the same charges repel each other.
Which particle of the atom has a positive charge?
The protons
Does this atom have a positive charge, a negative charge, or is it neutral?
It has a negative charge (it has more electrons than protons).
What type of electricity is this? (Static electricity or electrical current?)
Static electricity
Does this atom have a positive charge, a negative charge, or is it neutral?
It has a positive charge (it has less electrons than protons).
What do we call it when there is an exchange of electrons between many different atoms? (a flow of electrons)
Electrical current
What is the function of a switch in an electrical circuit?
It opens and closes the circuit.
What produces and transports an electrical current?
An electrical circuit / a closed electrical circuit
What do we call materials that do not allow electrons of move easily?
Electrical insulators
TRUE or FALSE: Neutrons attract electrons.
FALSE: Protons attract electrons because they have opposite charges
What is the function of a load in an electrical circuit?
It converts the electricity into another form of energy. ( A bulb converts electrical energy into light energy)
TRUE OR FALSE: The nucleus of an atom contains protons and neutrons.
TRUE: The protons and neutrons are in the nucleus and the electrons orbit around the nucleus.
Why are electrical wires made of copper covered in plastic? (Use the words electrical conductor /insulator)
The wire conducts electricity because copper is a conductor but the plastic on the outside of the wire protects us because it's an insulator.
Which particle of the atom has a negative charge?
The electrons
What are the 4 basic parts of an electrical circuit?
1) a power source / battery 2) a conductor / wire 3) a switch 4) a load / bulb
TRUE OR FALSE: Silver is an electrical conductor.
TRUE: Pure silver is the best electrical conductor.
TRUE or FALSE: If you see lightning at the beach, go swimming to stay safe.. (Explain your answer using the words insulator OR conductor))
FALSE: Sea water is an electrical conductor. If the lightning strikes the water, you can get a shock.
