What type of energy is the energy of motion?
Mechanical Energy
100
What energy transformation is happening when you plug in a television?
Electrical to sound 

and/or

Electrical to light

100
Electric energy can be transformed into sound, heat, and mechanical energy. What is an example of electrical to sound?
TV, radio, phone, computer, etc.
100
Name 3 examples of light energy.
Anything that gives off LIGHT! (phones, tv, computer, sun, lightbulb, etc)
100
What is a conductor?
An object that lets electricity flow through it.
200
What type of energy travels by vibrations?
Sound energy
200
Give an example of something that is both thermal and light energy.
Examples: candle, match, sun, light bulb...
200
For a light to turn on, does the circuit need to be OPEN or CLOSED?
CLOSED :)
200
What is an example of RENEWABLE energy?
Examples: The sun, wind, geothermal
200

True or False...

Metals are good conductors of electricity

TRUE
300
What is another word for "heat" energy?
Thermal
300
List the transformation of energy happening when you ring a doorbell.
Mechanical -> Electrical -> Sound.


Pressing the doorbell, the motion runs through the wires to make the sound. 

300
True or False...

You can place a rubber eraser in the middle of a closed circuit and it will still work.

FALSE. Rubber is an insulator, it will stop the flow of electricity. 
300
True or false...energy can cause change.
TRUE. Energy causes motion and creates change.
300

Wood, plastic, and paper are....

conductors or insulators?

Insulators. They do NOT let electricity flow through.
400
What type of energy needs to be plugged in/used by wires?
Electrical energy
400
True or false...energy can be stopped.
FALSE. Energy cannot be created or destroyed. Just moved from one thing to another. 
400
Which is NOT an example of electrical energy:


Playstation, Flashlight, Refrigerator, Stove

Flashlight! It runs on batteries. 
400
When two objects both have positive charges...will they ATTRACT or REPEL?
REPEL. Same charges repel. Opposite charges attract. (think of a magnet)
400

Name 5 objects in the room that are good conductors.

Examples: chair legs, table legs, door handle, metal on white board, etc.

500
Food and batteries are examples of what type of energy?
Chemical energy
500
A fan is an example of what type of energy transformation?
Electrical to mechanical
500
Draw a picture of a closed circuit 
Your picture should have a complete and connected circle to both ends of a battery to a lightbulb! (remember our experiments!)
500
Give an example of electrical to heat energy transformation. 
Examples: Oven, stove, microwave, lightbulb, etc. 
500
Name 5 objects in the room that are insulators.
Example: wood desk, plastic chair, erasers, plastic bins, paper books, etc.
