Electric (electron) movement
The smallest building blocks of everything that exists
What are atoms?
Particles moving between atoms in storm clouds become this.
What is charged?
This subatomic particle flows through the wire when an electric field is present.
What is an electron
What is the thing that closes and opens the current in a circuit.
What is a switch.
Every magnet has two of these
What are poles
charges that have no charge and are found in the nucleus of an atom
What are neutrons?
North and south poles do this
What is attract
this is a path in which electric charges can flow.
What is an circuit.
What is the purpose of a battery within an electrical circuit?
Convert chemical energy to electrical energy
Electric Current move easily in these.
What are conductors
When the positive and negative charges no longer balance. This is when negative charges are built up much more than positive.
What is static electricity?
This is the reason magnets might repel each other.
What is like poles.
What kind of energy transformation occurs in a radio?
Electrical/Chemical Energy is changed to sound energy
How does heat transfer?
Heat transfers from hotter to colder air
Transfer of electrons between objects in contact
What is charging by contact
An electric charge that is flowing.
BONUS: What evidence would help you make sure that the electrical current is flowing?
What is an electric current?
A light bulb connected to the current will turn on
These factors affect the strength of magnetic forces.
What are strength, size, distance....
Name things that could slow or inhibit the flow of electrons in a circuit.
BONUS: Give examples
What are insulators
Examples: wood plastic rubber
In this circuit, devices are connected so there is only 1 closed path for current to follow.
What is series
A current carrying wire wrapped around an iron core is called this.
What is electromagnet.
Particles in the atom that have negative charges
What are electrons
A magnet that uses electrical energy to pick up objects and can be turned off
What is an electromagnet
This subatomic particle flows easily in a circuit.
What is electron
This device uses radiant energy from the Sun to heat food
What is a solar oven
This is a measure of the amount of electrical energy transferred by an electric charge as it moves from one point to another in a circuit.
What is voltage
