About Science

1. About Science Chapter 1 Part 2

2. Roots of Science …are found in every culture

3. “If I have seen further it is by standing on the shoulders of Giants.” Isaac Newton

4. Ancient Greece

5. Grecian science was based onLogic&Mathematics

6. Physics Zoology Geometry Botany Public Waterworks Earth Science Sanitation Astronomy

7. Chinese • Printing • Compass • Rockets

8. India • Developed concept of zero and infinity

9. Guttenberg’s Printing Press – 15th C • Developed concept of zero and infinity

11. Galileo 16th Century • Used experiments • Earth revolves around the sun

12. Galileo 16th Century • Used observations • Used “objectivity” • Beginning of modern science

13. What about math? • About relationships between numbers

14. Math+ Science • Very Powerful Combination

15. Math+ Science • Very Powerful Combination • Understand Relationships

16. The Scientific MethodA Classic Tool Chapter 1 Part 3

17. Scientific Method An orderly method for gaining, organizing, and applying new knowledge.

18. Scientific Method 1. Observe (what do you see?) and Question (recognize a question or problem)

19. Scientific Method 2. Hypothesize Make an educated, testable guess (hypothesis) to answer the question

20. Scientific Method 3. Predict What will happen if the hypothesis is correct?

21. Scientific Method 4. Test the Prediction Experiment Are the predicted consequences present?

22. Scientific Method 5. Draw a Conclusion Make a simplified statement that summarizes the process and results

23. Scientific Method Observation A paper bag is on a counter - what is in it? Proposing a Hypothesis Inside is a sandwich Test the Hypothesis Smell, shake, feel Form a Conclusion Orange - wrong Lime- correct Revise the Hypothesis Lime

24. Scientific Hypothesis • Testable • There is a test for proving it right • More important to be capable of being proven wrong!

25. Let’s go back to Galileo His experimentation led to modern scientific practice.

26. Aristotle384 – 322 BC “Heavy objects fall faster than lighter objects”

27. Galileo disproved Aristotle’s claim with a single simple experiment.

28. But what if we dropped a feather and a hammer at the same time?

29. Galileo disproved Aristotle’s claim with a single simple experiment. YouTube - Feather & Hammer Drop on Moon

31. Facts, Theories and Laws They aren’t what you think they are…….

32. Fact • Something that observers agree is true. • It is testable. • Not necessarily absolute

33. For example….. • Fact – Salamanders are able to regenerate limbs.

34. Unfortunately, humans are unable to regenerate limbs.

35. Theory • Collection of facts and well tested hypotheses. • Continuously grow stronger and more precise with new information.

37. PlateTectonics

38. The Big Bang Theory

40. Law (Principle) • A hypothesis that has been tested over and over and has not been disproven

41. Law of Gravity

42. Science, Religion and Art …answering different questions

43. Science… provides information about the natural world and how it works “Cosmic Order”

44. Religion… Source Purpose Meaning “Cosmic Purpose”

45. Art… A means of producing beauty Stimulating thought “Cosmic truth and beauty”
