  • Transcript

    • 1. Nature of Scientific Inquiry “how to do science”
    • 2. AP BIO
      • 1. Design experiment to test 600X size. Turn in forms…
      • 2. Revamp on schedule … summer stuff due Tues w/ test due to new students, etc.
      • 3. Lab safety.
      • 4. Doing science.
      • 5. Lab – Fish homeostasis
      • Put on a poster what you might put in a lab report. ( one per group)
      • 6. Set up grow me.
      • 7. Lab Safety quiz HW…and summer HW
    • 3. Lab Report
      • Problem
      • Hypothesis
      • Materials
      • Methods
      • Data
      • Conclusion
    • 4. 1. Observations
      • Observe some aspect of your world. Learn what you can about it and form a question.
    • 5. 2. Develop a Hypothesis
      • … an education guess, not a blind one.
      • Using your hypothesis as a guide, make a prediction.
      • Sometimes take the form of an “if-then” statement.
      • “ null hypothesis” The null hypothesis is a hypothesis which the researcher tries to disprove, reject or nullify. Read more: http://www.experiment-resources.com/null-hypothesis.html#ixzz0PFpTDGN4
    • 6. 3. Test
      • Devise a test w/ systematic observations, building models and or conducting experiments.
      • Whenever possible a good experiment has:
      • 1. quantitative data ( #s)
      • 2. limited to one variable
      • 3. a control – standard for comparison
      • 4. can be repeated (avoid sampling error)
    • 7. Physics
      • Turn in forms, wordle for stamp
      • Warm up…Picture find lab errors
      • http://expedioscientiam.net/school/resources/what_not_to_do_600.pdf
      • Lab Safety
      • How to do Science Notes
      • Lab
      • Equipment sheet (HW)
      • Lab Safety Quiz
    • 8. DRY MIX
      • DRY – dependant responding variable (on y axis)
      • MIX – manipulated independent varialbe (on X axis)
    • 9. “the scientific method”
      • Not a fixed numbered procedure.
      • A fluid continuously modified process.
      • More of a logical approach to problem solving….
      • SCIENCE has to be “testable”.
      • SCIENCE is NOT an opinion or belief.
      • Beliefs and science do have to be mutually exclusive.
    • 10. About the word “theory”
      • … stronger than in our ordinary language.
      • Means that researchers have tested its predictive power many times and in many ways in the natural world and have yet to find evidence that disproves it.
      • Ex: theory or natural selection, Einstein’s theory of relativity.
      • Still don’t say it is absolute truth…but that it has a high probability of being true.
      • Scientists keep their eyes open for any new information and new tests that might disprove its premises.
    • 11. Limits of Science
      • Not everything can be “tested”.
      • Subject to our worldview ( ask Galileo)
      • Personal bias (funding)
      • Limited by our technology
