200
This is what happens when rising water vapors condense, or cool.
What forms clouds
200
Light bending as it moves between matter

What is a thermometer
200
The speed and direction of an object. Example: Bicyclists riding their bikes forward on a trail, at a fast speed.
What is velocity
300
A group of stars that make an imaginary picture.
What is a constellation
300
This can be described as dry and cold near the north/south poles, and warm and humid closer to the equator.
What is an air mass
300
A lens that causes light waves to bend inward and makes objects appear smaller. The lens is wide in the middle, narrow at the ends.
What is a convex lens
300
An instrument that measures air pressure
What is a barometer
300
A change in the speed or direction of an object in motion. Example: bicyclists slowing down to stop their bikes, or turning a corner.
What is acceleration
400
This causes the sun to appear to move during the day, and the starts to appear to move at night.
What is the Earth's movement

Forms where two air masses meet; can either be warm or cold.
What is a front

This lens causes light waves to bend outward (spread apart) and make objects look bigger.
What is a concave lens
400
An instrument that measures the amount of water vapor in the air
What is a hygrometer
400
The property of matter that keeps an object from changing speed or direction unless a force acts on it. Example: The bicyclists will continue coasting on their bikes until they apply their brakes and stop.
What is inertia
500
This is what causes the moon to appear to change shape, become full, or go in to "new moon phase".
What is the moon revolving around the Earth, and the Earth revolving around the Sun.
