100
Define Mass.
What is the amount of matter in an object.
100
The atmosphere is
What is the layer of air surrounding Earth.
100
Define Compressed.
What is forced into a smaller space.
100
What is a wind vane used to measure and what unit is it measured in?
What is an instrument to measure wind direction. Compass points (North, South, East, West).
100
Define Meteorology and Meteorologist.
What is the scientific study of Earth's weather. What is the person who studies the weather.
200
Define Weight.
What is the pull or force between Earth and the matter in an object or substance.
200
Where does Earth's weather occur?
What is in the Troposphere.
200
Define Pressure.
What is the push when compressed air pushes back.
200
Name the instrument used to measure temperature and the unit it is measured in.
What is a Thermometer. Degrees Celsius and Degrees Fahrenheit .
200
Define severe weather and give two examples.
What is weather that is dangerous or causes damage. Tornado, Hurricane, Flooding, or Blizzard.
300
Name two examples of objects or substances that have mass. Name two examples of objects or substances that have weight.
What is air and a person. (Many different examples work.)
300
What are the two most plentiful gases in the atmosphere?
What are Oxygen and Nitrogen.
300
Is there more air, less air, or the same amount of air in a syringe when the air is compressed into a smaller area?
What is same amount.
300
A Hygrometer measures what weather factor. Explain what this weather factor is and what unit is used to measure it?
What is Humidity and it is the amount of water vapor in the air. It is measured as a percent.
300
Explain/Define forecast and give an example using today's weather.
What is a prediction about what kind of weather to expect. Answers will vary.
400
Do an empty balloon and a blown up balloon have the same mass? Weight? Explain.
What is no, the inflated balloon is filled with air. The air has matter making up mass. The deflated balloon only has the mass of the balloon itself. They do not have the same weight because weight is based on the pull between Earth and the matter in an object. The inflated balloon has more matter, creating more pull, and more weight.
400
What layer of the atmosphere is where meteors burn up and to create shooting stars?
What is the mesosphere.
400
How do the number of molecules in the syringe change when the air is compressed? Explain.
What is the number stays the same. When air is compressed it does not lose molecules it is just forced into a small area and the molecules are closer together.
400
An Anemometer measure what? How do you use an anemometer? Explain the process and the units used.
What is an instrument to measure wind speed. It is used by standing the direction of the wind and allowing the wind to blow over the openings. It can be measure in mph or km/h.
400
Explain/Define weather factors. Name four weather factors.
What is properties of air that affect weather. Temperature, Humidity, Wind Direction, Wind Speed, and Air Pressure.
500
Does air have mass? Prove your answer.
What is yes. Balloon investigation proves this.
500
What percent of the atmosphere's height is made up of the troposphere? What percent of the Earth's air is found there?
What is 2% and 85%.
500
What creates the pressure inside of the syringe?
What is the molecules are forced into a smaller area, so they begin to bounce off one another more quickly creating pressure inside the syringe.
500
Explain what a Barometer is used to measure and what that actually is. What unit is it measured in?
What is a device used to measure air pressure. Air pressure is the force of air pushing in all directions. It is measured in millibars or inches of mercury.
500
Explain three different weather conditions and how they can cause property damage. Is severe weather the only weather that can cause damage.
What is rain, snow, sun, hail, tornado, hurricane, ect. No, everyday weather can cause damage. Over time sun and rain can both cause damage.
