100
Heat always flows in this direction.
What is from the hot object to the colder object?
100
Conductors are all made out of this type of material.
What is metal?
100
What is wrong with this circuit?
It is not a complete loop.
100
The energy transformation in a light bulb.
What is electrical to light and thermal?
100
What is necessary for an electromagnet to work?
The flow of electricity.
200
Heat energy being transferred from the sun is an example of this type of heat transfer.
What is radiation?
200
Plastic is an example of this.
What is an insulator?
200
When this is on the circuit is closed allowing electricity to flow. When this is off the circuit is open stopping the flow of electricity.
What is a switch?
200
The energy transformation in an oven.
What is electrical to thermal?
200
The flow of electricity creates this around a metal object.
What is a magnetic field?
300
Warm water moving in a pot of boiling water or warm air moving in a green house is an example of this type of heat transfer.
What is convection?
300
Foam or Styrofoam is an example of this.
What is a heat insulator?
300
All electric circuits need certain components in order to work. This MUST be part of an electric circuit.
What is a battery or power source?
300
The energy transformation in a generator.
What is mechanical or energy of motion to electrical?
300
Earth and a magnet both have these.
What is a North and South pole? What is a magnetic field?
400
Your hand melting an ice cube or food cooking in a pan is an example of this type of heat transfer.
What is conduction?
400
Which object is classified incorrectly?
What is the wooden craft stick?
400
When the switch is closed, and light bulb A is removed this will happen because it is this type of circuit.
Light bulbs B and C will not light because it is a series circuit.
400
The energy transformation in a hair dryer?
What is electrical to energy of motion or mechanical, sound and thermal?
400
You can use this object to help find the north and south pole of an electromagnet.
What is a compass?
500
Heat will flow from one object to another until this happens.
What is until they are the same temperature?
500
The rubber insulation of the was cut off the end of the wire in order to expose the copper. The wire was used to complete an electrical. What is the reason for exposing the copper part of the wire?
So that electric current can pass between the copper wire and other parts of the circuit
500
When the switch is closed, and light B goes out this will happen to the other light bulbs because it is this type of circuit.
Light bulbs B and C will stay lit because it is a parallel circuit.
500
The energy transformation in a windmill.
What is energy of motion or mechanical to electrical?
500
What are the three ways you can make an electromagnet stronger?
Make more coils.
Use a metal core.
Increase the voltage of electricity.
