Electricity
The buildup of electric charge on an object
What is static electricity?
Any materials that attract iron or objects made of iron
What are magnets?
An educated guess that you write at the start of an experiment using the "If____, then___." format
What is hypothesis?
The opposition to the flow of electric charge, measured in Ohms.
What is resistance?
A material through which charges can move freely
What is an electrical conductor?
A push or pull resulting from spinning electric charges in the magnets
What is magnetic force?
A circuit where electric charge cannot travel
What is an open circuit?
A list of all the items you will use in an experiment
What are materials?
One way that an object can become electrically charged
A material through which charges cannot move easily
What is electric insulator?
The area around a magnet where magnetic forces can be detected
What is a magnetic field?
All parts are connected in a row with one path for electric charges to follow
What is series circuit?
A visual representation of data, usually used to show comparisons between individual categories
What is a bar chart/bar graph?
This results when electric currents and magnetic fields interact with each other
What is electromagnetism?
This happens when two objects have opposite charges
What is attract/move closer?
The ends of a magnet
What are poles/magnetic poles?
Parts are connected side by side, and electric charge has more than one path to follow
What is parallel circuit?
A visual representation of data that shows change over time
What is a line graph?
An object with no charge is ______.
What is neutral?
This happens when two objects have the same charge
What is repel/move apart?
The name of the coil wrapped around an iron core to create an electromagnet
What is a solenoid?
The three parts of an electric circuit
Energy source (battery), electrical conductor (wire), and load (bulb)
The end of the scientific method that sets up for the next experiment
What are future questions?
Voltage = Current x resistance
What is Ohm's law?
