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.

Independent Variable = labs

Dependent Variable = unit test averages

Hypothesis = If one class does labs and the other does not, then the class with labs will score higher on the test.

Control Group = class without labs

Experimental Group = class with labs

Constants = identical notes, homework, and unit test for both classes

Possible threats = I’m not sure, sorry!

1. Independent Variable – This is the element changed or controlled in an experiment. Here, it is the labs, since they are given to one class but not the other.

2. Dependent Variable – This represents what is measured in the experiment and depends on the independent variable. In this case, it is the average test scores.

3. Hypothesis – A testable prediction. Here, it suggests that the class participating in labs will perform better than the one without labs.

4. Control Group – The group that does not receive the experiment variable; in this example, the class without labs.

5. Experimental Group – The group exposed to the variable being tested, here the class that completes labs.

6. Constants – The same quantity and type of notes and homework provided to both classes.

7. Possible threats to accuracy – Potential issues include improper application of independent or dependent variables, or misuse of statistical analysis, among others.
