Mrs. O'Grady wants to know if doing labs with
her science class really helps them learn the
material better. She decides to test this out in her
two 6th grade science classes. In both classes she
gives the same amount and type of notes and
homework, but in one class she does labs and the
other class she doesn't. At the end of the unit,
she gives both classes the same unit test and
compares the class averages.
