Revolution
The movement of earth as it spins on its axis
Rotation
The phase of the moon where the moon appears totally dark.
New moon
The phase of the moon where half of the moon is visible.
Quarter moon.
The phase of the moon where we see the entire half of the moon that is lit.
Full moon.
A small section of the moon facing Earth is lighted.
Crescent

Reflection
The bending of light when light passes from one transparent material to another.
Refraction
Soaking up light when it strikes an object.
Absorption
A material that allows light to pass through

This device allows you to open and close a circuit
A switch
This provides a source of power in an electric circuit
A battery
This object in a circuit changes electricity into light
A bulb
In this type of circuit there is only one path for electricity to flow (one bulb out means they all go out)
Series circuit
In this type of circuit there are multiple paths of electricity (if one bulb goes out, the others remain lit).
Parallel circuit
Liquid water on earth becomes a gas called water vapor
Evaporation
Water vapors turn back into liquid water droplets to form clouds
Condensation
