1. What is the main problem with one scientist describing a day as 'warm' and another describing it as 'scorching'?
- A. These words are not based on precise, repeatable measurements.
- B. The word 'scorching' is too dramatic for a scientific report.
- C. Only a meteorologist is allowed to use descriptive weather words.
- D. These words mean the exact same thing.
2. If scientists around the world did NOT use standard units for their measurements, what would be the most likely consequence?
- A. Scientific instruments would stop working correctly.
- B. It would be very difficult to share, compare, and verify scientific data.
- C. The weather would become more unpredictable.
- D. Each scientist would have to invent their own measurement system from scratch every day.
3. A team is looking for a new forest to plant special trees that can only survive between 70 and 80 degrees Fahrenheit. Which piece of data is most helpful?
- A. Report A: The forest feels pleasantly warm most of the year.
- B. Report B: The forest's average summer temperature is 75°F.
- C. Report C: The forest gets a lot of visitors in the summer.
- D. Report D: The forest has many sunny days.
4. Why do meteorologists use standard units, like degrees, to measure temperature instead of words like 'hot' or 'cold'?
- A. To make the weather forecast sound more scientific and complicated.
- B. Because standard units are the only measurements that thermometers can show.
- C. So that all scientists can understand and compare temperature data accurately, without confusion from personal opinions.
- D. To prove that their specific location is warmer or colder than other places in the world.
5. A scientist who studies weather patterns and makes forecasts is called a:
- A. Geologist
- B. Biologist
- C. Meteorologist
- D. Chemist
6. Which of these is a measurement of temperature?

- C. Partly cloudy skies
- D. 10 miles per hour wind
7. Which of the following is NOT a scientific weather variable?
- A. A comfortable breeze
- B. Air pressure in millibars
- C. Rainfall in millimeters
- D. Temperature in degrees Celsius
8. Why do scientists use weather variables like temperature instead of just saying it is 'warm' or 'cold'?
- A. Because 'warm' means the same thing to everyone.
- B. Because variables provide specific numbers that allow for accurate comparisons.
- C. Because scientific instruments can only measure variables.
- D. Because using words is an older, less scientific method.
