Jamal and Jin live in different parts of the state. Jamal lives in the mountains and is not near a city. Jin lives at sea level, near a city.

They are talking on the phone at night. They look at the same part of the sky with the same kind of telescope. They expect to see the same number of stars, but they do not. Jamal is able to see many more stars than Jin. They want to find out why.

What should Jamal and Jin do to find out why they see different numbers of stars?

• They should assume Jamal’s telescope is broken.
  

• They should discuss the reasons for the difference.
  

• They should guess that the sky over Jin has fewer stars.
  

• They should believe one of them made a counting mistake.
  

Several classes of students wanted to know if the temperature of the soil changed with the temperature of the air. They recorded the temperature of the soil and the air in the same place, three times a day, for three days. Each class made a chart. At the end, two classes compared charts. Their results were different.

What could the students in the two classes do to figure out why their results were different?

• They could see which chart looks the best.
  

• They could go to a third class and copy their results.
  

• They could check each others’ work and look for mistakes.
  

• They could let the teacher tell them whose numbers are correct.
