Vocabulary
An electric charge in motion is called this.
What is an electric current?
This happens when positive and negative charges no longer balance.
What is static electricity?
For a current to flow, electric charges must complete this.
What is a circuit?
This cannot be made or destroyed.
What is energy?
Televisions, computers, and light bulbs are all examples of this.
What are resistors?
This is a material through which an electric charge can move easily.
What is a conductor?
Which of these materials is a conductor: rubber, chalk, gold or glass?
What is gold?
Electric current cannot flow in a series circuit if this happens.
What is there is a break in the circuit?
A washing machine is an example of transforming what into motion energy?
What is electricity?
Most resistors transform electrical energy into these two things.
What are heat and light?
This is a material through which an electric charge moves with difficulty.
What is an insulator?
Which material would be the best insulator for a metal wire? silver, graphite, glass, or copper?
What is glass?
These are the four parts of a circuit.
What are the energy source, resistors, wires, and the switch?
Which of the following is caused by the energy of motion: resistor, friction, conductor, or filament?
What is friction?
Which of these uses resistors to transform electricity into heat? Toaster, car engine, gas stove, or wind turbine?
What is a toaster?
This is a type of circuit where an electric charge can flow in only one circular path.
What is a series circuit?
One example of a resistor is what: a power cord, a parallel circuit, a battery, or a filament?
What is a a filament?
In this type of circuit, electricity will still flow through the unbroken loops.
What is a parallel circuit?
Name two objects that transforms electrical energy to sound energy?
What are radios, tvs, cell phones, tablets, etc.?
When electrical currents pass through a resistor, it often gives this off.
What is heat?
Rudolph the Red-Nosed Reindeer probably had one of these in his nose, since it glows.
What is a filament?
What are the tiny building blocks of everything, and the 3 charges they usually have?
What are atoms, and positive (proton), negative (electron), and neutral/none (neutron)?
Classify each part of a flashlight (light bulb, handle, wire, on/off button, battery) as a conductor, an insulator, a resistor, an energy source or a switch.
Energy cannot be made or destroyed but it can do this.
What is transform?
Name two examples of appliances that glow red due to coils of wires.
What are toasters, ovens, hair dryers, etc.?
