• How far you go in life depends on you being
  tender with the young, compassionate with the
  aged, sympathetic with the striving, and tolerant
  of the weak and the strong. Because someday in
  life you will have been all of these.

Postquiz Activities

• Hand in quiz
• Place it in the tray
• Pick up a W.S. Deer Predation or Starvation on
  the lab stool
• Work on the worksheet or correct homework

5
W.S. Deer Predation or Starvation

• Make the graph on the second page
• Note that the number of deer are listed on the
  left vertical axis while the number of wolves are
  listed on the right vertical axis
• The third question is on the last page

6
Terminology

• Variable - the factor that was different between
  groups
• Control group - not exposed to variable
• Experimental group - exposed to variable
• repeatable - all experiments have to be able to
  be repeated
• Falsifiable it has to be able to be proven
  untrue

7
Scientific Method

• Hypotheses are not guesses, they are possible
  explanations to the problem
• A hypothesis that is not supported by data
• Usually predicts a different observation
• Scientists design experiments with a result in
  mind
