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?
A. They could see which chart looks the best.
B. They could go to a third class and copy their results.
C. They could check each others’ work and look for mistakes.
