  • How to get a good grade
  • Attend class and lab
  • Attend the field trips
  • Print the powerpoint lectures before class and
    take notes on them
  • Read the book
  • Study for the exams (seriously)
  • Turn in assignments on time
  • Do not cheat or plagiarize
  • Do the extra credit work

Marine Biology
  • The study of the organisms that live in the sea

Tools of Marine Biology Scientific Method
  • Observe, describe
  • Coral reef

9
Tools of Marine Biology Scientific Method
  • Observe, describe
  • Stony corals
  • Animal polyps have algae cells inside

10
Tools of Marine Biology Scientific Method
  • Observe, describe
  • Corals once green and brown are now white
  • Water temperatures were 30C (86F) or more for
    several weeks

11
Tools of Marine Biology Scientific Method
  • Ask questions
  • Why did the corals turn white?
  • Did the warm temperatures cause the problem?
    Pollution? Salinity changes? UV?
  • Is it permanent or will the coral recover?

12
Tools of Marine Biology Scientific Method
  • Choose one question to address, then create a
    hypothesis
  • The prolonged warm water temperatures caused the
    bleaching

13
Tools of Marine Biology Scientific Method
  • Conduct a controlled experiment to test the
    hypothesis
  • Collect some identical corals
  • Place some in normal temperature water and
    others in warmer water

14
Tools of Marine Biology Scientific Method
  • Experiment results, statistics
  • Corals in lab held in the warmer water
    bleached after several weeks while those in the
    control water did not

15
Tools of Marine Biology Scientific Method
  • If confirmed, then more tests of the hypothesis
  • Experiment must be repeatable
  • Test other species, temperatures, time frames
  • If not, then test an alternative hypothesis

16
Tools of Marine Biology Scientific Method
  • Theory
  • After the hypothesis has passed extensive
    testing and is accepted as true, it may be
    considered a theory
  • Explanation supported by evidence
  • Beware of misuse (scientific theory is not a
    guess, thats a hypothesis)
