light- the screen produces
sound- the speaker makes noise
200
What is the difference between a thermal conductor and an insulator and give an example of each
Conductors helps the flow of energy
example: Penny, iron nail, Metal
Insulator stops or keeps the flow of energy in
example: wood, plastic
300
Reflection
The bouncing back of light rrays from a surface.
300

Friction
300
Draw a picture of a Series circuit.
300
If you shine a light from position E where would it reflect off of and Why? 
Position A because light travels in a straight line until it is int his case reflected. The angle of incident will be the same as the angle of reflection.
