Imagine that you are part of Mr. Rodriguez's chemistry class. Your class always compares test scores with those of
students in Ms. Zakula's class. You feel superior to the students in her class and never share notes or ideas with them. In
fact, everyone in your class thinks that the other class is for "dummies" while your class, of course, has only the best
students. One day, you find out that your school will be competing against North High in the science fair. Both your class
and Ms. Zakula's class will be working together in the competition against North High.
