    • 1. Nature of Scientific Inquiry “how to do science”
    • 2. AP BIO <ul><li>1. Design experiment to test 600X size. Turn in forms… </li></ul><ul><li>2. Revamp on schedule … summer stuff due Tues w/ test due to new students, etc. </li></ul><ul><li>3. Lab safety. </li></ul><ul><li>4. Doing science. </li></ul><ul><li>5. Lab – Fish homeostasis </li></ul><ul><li>Put on a poster what you might put in a lab report. ( one per group) </li></ul><ul><li>6. Set up grow me. </li></ul><ul><li>7. Lab Safety quiz HW…and summer HW </li></ul><ul><li> </li></ul>
    • 3. Lab Report <ul><li>Problem </li></ul><ul><li>Hypothesis </li></ul><ul><li>Materials </li></ul><ul><li>Methods </li></ul><ul><li>Data </li></ul><ul><li>Conclusion </li></ul>
    • 4. 1. Observations <ul><li>Observe some aspect of your world. Learn what you can about it and form a question. </li></ul>
    • 5. 2. Develop a Hypothesis <ul><li>… an education guess, not a blind one. </li></ul><ul><li>Using your hypothesis as a guide, make a prediction. </li></ul><ul><li>Sometimes take the form of an “if-then” statement. </li></ul><ul><li>“ null hypothesis” The null hypothesis is a hypothesis which the researcher tries to disprove, reject or nullify.

    • 6. 3. Test <ul><li>Devise a test w/ systematic observations, building models and or conducting experiments. </li></ul><ul><li>Whenever possible a good experiment has: </li></ul><ul><li>1. quantitative data ( #s) </li></ul><ul><li>2. limited to one variable </li></ul><ul><li>3. a control – standard for comparison </li></ul><ul><li>4. can be repeated (avoid sampling error) </li></ul>
    • 7. Physics <ul><li>Turn in forms, wordle for stamp </li></ul><ul><li>Warm up…Picture find lab errors </li></ul><ul><li>http://expedioscientiam.net/school/resources/what_not_to_do_600.pdf </li></ul><ul><li>Lab Safety </li></ul><ul><li>How to do Science Notes </li></ul><ul><li>Lab </li></ul><ul><li>Equipment sheet (HW) </li></ul><ul><li>Lab Safety Quiz </li></ul>
    • 8. DRY MIX <ul><li>DRY – dependant responding variable (on y axis) </li></ul><ul><li>MIX – manipulated independent varialbe (on X axis) </li></ul>
    • 9. “the scientific method” <ul><li>Not a fixed numbered procedure. </li></ul><ul><li>A fluid continuously modified process. </li></ul><ul><li>More of a logical approach to problem solving…. </li></ul><ul><li>SCIENCE has to be “testable”. </li></ul><ul><li>SCIENCE is NOT an opinion or belief. </li></ul><ul><li>Beliefs and science do have to be mutually exclusive. </li></ul>
    • 10. About the word “theory” <ul><li>… stronger than in our ordinary language. </li></ul><ul><li>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. </li></ul><ul><li>Ex: theory or natural selection, Einstein’s theory of relativity. </li></ul><ul><li>Still don’t say it is absolute truth…but that it has a high probability of being true. </li></ul><ul><li>Scientists keep their eyes open for any new information and new tests that might disprove its premises. </li></ul>
    • 11. Limits of Science <ul><li>Not everything can be “tested”. </li></ul><ul><li>Subject to our worldview ( ask Galileo) </li></ul><ul><li>Personal bias (funding) </li></ul><ul><li>Limited by our technology </li></ul>
