100
A material through which electricity flows easily.
What is a conductor?
100
The flow of electrons around a circuit.
What is electric current?
100
A "cell" that is the source of electrical energy in a circuit.
What is a battery?
100
True or False- rubber is a great insulator!
True! Wires are coated in a rubber or plastic coating to protect us from electric current.
100
True or False- A person can conduct electricity.
What is True? When we joined hands, we were able to create a circuit of electric current through our bodies.
200
A material that does not conduct electricity.
What is an insulator?
200
What three things do you need to build a simple electric circuit?
1. A source of electric charge, such as a battery. 2. A device, such as a lightbulb, that changes electric energy into another form of energy, like light. 3. Wire that connects the battery and lightbulb in a loop.
200
The thin wire in a lightbulb that does not like electrons flowing through it, so it creates heat and light.
What is a filament?
200
A temporary magnet made when electric current flows through a wire coil wrapped around an iron or steel core.
What is an electromagnet?
200
The tiny building blocks of matter.
What is a atom?
300
True or False- Copper is a great insulator!
What is False? Copper is a conductor because electric current can flow easily through copper wires.
300
A circuit that has only one path for electric current to follow.
What is a series circuit?
300
These open and close circuits to stop and start the flow of electricity.
What is a switch?
300
True or false- There is only one way to connect a circuit in order to light a lightbulb.
False- during our experiments, we found many ways to arrange a battery, lightbulb, and wire.
300
Why are homes designed with parallel circuits?
Homes are designed this way so that you can turn off the lights and still watch a movie and make popcorn in your microwave!
400
True or False- Salt water can conduct electricity.
What is True? In our liquid conductors experiment, many groups were able to light a bulb using salt water as a conductor.
400
A circuit that has more than one path for electric current to follow. This circuit splits into branches, so when one branch goes out, the others still work.
What is a parallel circuit?
400
These can be positive or negative.
What is an electrical charge?
400
Give three examples of how you use electricity to get ready in the morning.
Answers vary.
400
Give one example of how electricity is converted into heat energy in your home.
Answers vary. Example: Oven or iron
500
Name an example of a conductor and an insulator found in our classroom!
Answers vary.
500
What is the difference between an open and a closed circuit?
If any parts of a circuit become disconnected, this is an open circuit. In a closed circuit, all parts are connected in a continuous loop.
500
A non-current form of electricity made by rubbing two items together.
What is static electricity?
500
Energy sources that cannot be replaced. For example, coal and oil.
What are nonrenewable resources and/or fossil fuels?
500
What unit of measurement do we use to measure the amount of electricity flowing through a circuit?
What is volts?
