7. CONSTANT factors that are the same between the control and independent variable

8. Hypothesis: Plants grow taller with fertilizer Control Independent variable Dependant variable is

9. Constants will be

10. Now, Work in groups to answer the questions for the 3 scenarios. If you do not finish, it is homework.
