An invisible mixture of gases which make up the earth's atmosphere.

What is AIR?

100

Approximately one kilogram of air presses down on each square centimeter of your body.

What is property- AIR EXERTS PRESSURE?

100
Something we change in the experiment.
What is the MANIPULATED (or Independent) VARIABLE?
100
This causes air molecules to gain in energy.
What is HEAT?
100

WHY IS COLD AIR MORE DENSE?

MORE MASS, LESS KINETIC ENERGY, ANSWERS VA

RY.

200

The layers of air that surrounds the earth.

What is the ATMOSPHERE?

200

Our experiment, DIVING PAPER, where we immersed an inverted glass, with paper inside, in a bowl of water.

What is the property- AIR TAKES UP SPACE?

200
The part of our experiment that we keep the same.
What is the CONSTANT (or Control) VARIABLE?
200

WHAT IS AN EXAMPLE OF COMPRESSED AIR IN EVERYDAY LIFE?

ANSWERS VARY

300
The force exerted on the surface of objects by weight of air particles. It acts in all directions and increases with an increased concentration of air molecules.
What is AIR PRESSURE?
300

When air molecules are forced into a smaller space.

What is the property- AIR CAN BE COMPRESSED?

300
The part of our experiment that we measure.
What is the RESPONDING (or Dependent) VARIABLE?
300
This happens to air molecules as they are heated.
What is MOVE FURTHER APART?
300
It extends some 450 kilometers into space and surrounds the earth.
What is our ATMOSPHERE?
400

Candle flames burn up ________ in the air.

What is OXYGEN?

400
A balloon filled with air weighs more than a deflated balloon.
What is the property- AIR HAS MASS?
400
In our Paper Airplane Example we measured how far the planes flew.
What is the RESPONDING (or Dependent) VARIABLE?
400
A given amount of heated air has less of this than does the same volume of cooler air.
What is LESS MASS ( or less dense)?
400
It decreases as you go up in altitude and is greatest at sea level.
What is Air Pressure?
500
The science dealing with the study of objects moving through air.
What is AERODYNAMICS?
500

A balloon put in hot water changes the size of the balloon.

What is the property- AIR EXPANDS WHEN HEATED AND CONTRACTS WHEN COOLED?

500
If we conducted the Paper Airplane Experiment outside, we would change this variable.
