The tiny building blocks of everything. They're tiny and they're teeny!
What are atoms?
Particles moving between atoms in storm clouds become this. (Think of the lab we did with the balloons)
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. (Think lights!)
What is a switch.
Every magnet has two of these
What is a magnet pole?
The same number of positive particles as negative particles.
What is neutral?
North and south (opposites) poles do this
What is attract
this is a path in which electric charges can flow.
What is an circuit.
This is the SI unit of electric current.
What is V or voltage
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 the same poles.
Name things (2) that electrons flow easily through.
What is wire, metal poles, pencil lead, anything metal.
What factors affect the strength of electric forces?
resistance, amount of electricity, # of bulbs.....
An electric charge in motion. (electrons in motion usually in a wire)
What is an electric current?
These factors affect the strength of magnetic forces.
What are strength, size, distance.
Name at least 2 things that could slow the flow of electrons in a circuit.
wood plastic rubber
Electric currents are surrounded by these....
What is an electric fields
Only materials containing these elements are magnetic
What is iron, cobalt, nickel, and a few other rare earth elements (metal)
This subatomic particle flows easily in a circuit.
What is electron
