Attempt to find out how and why things look and behave.
the study of living organisms and their vital processes
Biology
Why do we need to do experiments many times over?
Allows us to get the best possible answer
Makes it valid
the variable that the scientist manipulates
independent
What are 2 constants in this experiment?
-amount of dishwashing liquid used
-amount of water
-water temperature
-# of dishes
-kind & amount of grease applied to dishes
-brand of paper towels used & the manner in which you wiped down the dishes
What do you do after you ask a question?
gather information (do research, read materials)
