2. Is Seeing Believing?

4. THE NATURE OF SCIENCE

5. MAIN IDEAS SUPPORTING DETAILS

6. Nature of Science Notes AIM/GOAL OF SCIENCE To understand the world around us

7. Nature of Science Notes AIM/GOAL OF SCIENCE LIMITATION To understand the world around us Limited to the natural (A.K.A. material) world

9. Nature of Science Notes AIM/GOAL OF SCIENCE LIMITATION CRITICAL THINKING To understand the world around us Limited to the real (material) world Science and CT go hand-in-hand

10. Nature of Science Notes ASSUMPTIONS 1. 1.The world is real 2. 2.We can know about the world 3. 3.Uniformity Things are the same everywhere e.x. Gravity 4. 4.Natural/Natural “willy and ethel cartoon”

11. Nature of Science Critical Thinking Does NOT take things for granted Does NOT rely on authority Individual consideration Duh! –Truth is not obvious Uncertainty = Reality INDIVIDUAL DECISION- MAKING!

12. REALLY… SCIENCE + CRITICAL THINKING = TRUE LOVE!

13. NATURE OF SCIENCE Science and Society It is a two-way street! –SCIENCE influences society –SOCIETY influences science soooo…. –SCIENCE SOCIETY Examples: –Abortion –Stem Cell Research –Global Warming

15. A TIMELY COMPARISON! BUSH ADMIN –"We do not know how much effect natural fluctuations may have had on warming.“ –Banned certain types of abortion methods within the limits of Roe vs. Wade –Banned stem cell research with embryos OBAMA ADMIN –“Global warming is real, is happening now and is the result of human activities.” –Will uphold Roe vs. Wade; wants states to legislate abortion rights –Wants to lift ban on embryonic stem cell research

16. QUICK THOUGHTS Based on your experience with the checks activity, define the word hypothesis WITHOUT using “guess”, “educated”, or “theory”

17. Nature of Science Notes Types of Scientific Knowledge Hypothesis: –Statement based on evidence hasn’t been proved true or false yet –Prediction used in expt. Based on evidence; assume what will or has happened –Estimation thought out about info given –Statement that predicts the outcome of a sitiiation –Decribe thoughts based on obser & infer.

18. Nature of Science Characteristics of Scientific Knowledge Uncertain –Use word “confidence” instead of certain Contingent Evidence NOT proof! –Evidence = OBSERVATIONS & INFERENCES! Modifiable –can change conclusions based on new knowledge –new observations and inferences

19. QUICK THOUGHT How did the Checks Activity demonstrate the characteristics of scientific knowledge that we just talked about?

20. Nature of Science Notes Types of Scientific Knowledge Hypothesis: Testable statement based on observation Theory: EXPLANATION of a set of observations LOTS of data! Has been repeatedly confirmed! Fact: Agreed-upon observation Ex. 206 bones in human body Can change, too!

23. REFLECTION Write about –3 NEW insights about science that you have gained so far this year –2 things that are similar to what you have learned in past science classes –1 question you still have about the Nature of Science
