How can you conserve energy?
turn off electrical item when not in use
100
miss freeman plays what instrument? how does it create sound?
piano, through hammers and vibrations
100
Water droplets, as in a rainbow, can separate white light into its different colors. What else does this?
A prism
100
the transfer of thermal energy from object to another is called
heat
100
materials that do NOT allow the flow of electric current are called
insulators
200
Energy that CANNOT be replaced is called
Nonrenewable energy
200
All sounds are produced by
particles of air vibrating
200
Light travels out from a light source in...
Straight lines


200
thermal energy always moves from 
matter that is warmer to matter that is cooler
200
you can make a complete closed circuit by using
a bulb a battery and a large paper clip
300
the amount of energy wave has determines its 
amplitude 
300

Sound cannot travel through outer space but light can. Why?

Light travels by electromagnetic waves which can transfer light waves but not sound waves

300
Convex and concave lenses have different effects on the images that is seen through them because they
refract light differently
300
when thermal energy is transferred between objects that are touching it is called
conduction
300
you can turn on and off the complete path of an electric current by adding a 
switch


400
how do humans get energy?
by eating food
400
Sound travels fastest through which matter
solids
400
An object that doesn't allow ANY light to pass through is called 
Opaque
400
energy from the sun is transferred to the earth by
radiation
400
why would you get an electric shock?
if the circuit was broken 
500
What is the law of conservation of energy?
Energy changes from on for to another but the total amount of energy does not change
500
the length of a wave is measure from a point on one wave to the same point on the next wave it is called
wavelength
500
When light waves bounce off an object it is called 
reflection
