3. Branches of Sciences Social Science Natural Science

4. The Natural Sciences Life Science Earth Science Geology, Astronomy Physical Science Physics, Chemistry

5. The Nature of Science Chapter 1

6.  Science is the pursuit of observing facts in order to understand the world we live in

7. Go Bananas!  Observing facts  Use your senses  Inference  Use what you already know

8.  Pure Science is the search for scientific knowledge  Technology is the application of that knowledge

9.  Science is a process not a set of facts.  Information about the world around us is always changing.

10.  Always starts with a question.  Searching for an answer is doing Science

11. A problem solving attitude think critically about a question test possible answers collect data unbiased observations

12. Toxic Waste Activity

13. The Scientific Method a systematic approach to problem solving a way of thinking using logic and reason NOT a rigid set of steps

14. Scientific Theory explanation that has been tested by repeated observations always being questioned and examined a possible explanation

15. Scientific Law a summary of natural events states a repeated observation about nature quantitative/qualitative

16. Scientific Model a representation of an object or event can be studied to understand the real object or event

17. Facts and Fiction Historical Facts a true statement about the existence of something or about a past event

18. based on physical evidence  fossil, skeleton, ruins based on recorded evidence  writings, drawings

19. Facts and Fiction Scientific Facts based on observation  using the 5 senses  must be measurable and repeatable

20. Facts and Fiction Tools scientists use to make observations microscope telescope spectrophotometer

21. Facts and Fiction Universal Statements either includes everything or excludes everything can’t be proven by observation

22. Facts and Fiction Value judgments placing value on things observation can not determine value

23. Facts and Fiction Biblical Truth the Bible claims to be the Word of God (II Tim 3:16) eternal spiritual importance

24. Evidence  fulfilled prophecy  accurate records of history  accurate descriptions of world  inner testimony of believer

25. Mathematics Language of Science International System of Units SI Units are used for consistency Table 1-1 page 16

26. SI Units based on the metric systemmetric system Prefixes for very large or very small measurements Table 1-2 &1-3 page 16

27. Kilo 1000 Hecto 100 Deka 10 Basic Unit Deci.1 Centi.01 Mili.001

28. SI Units Practice on page 17 Making Measurements page 18 copy Vocab into Notes

29. Scientific Notation method for recording very large or very small numbers reduces the number of zeros (powers of 10)

30. Significant Numbers the digits in a measurement that are known with certainty shows the accuracy of the tool being used

31. Significant Numbers Accuracy – extent to which the measurement approaches the true value Precision – degree of exactness of a measurement

32. Organizing Data made easier to read with charts or graphs choose method that will be easiest to read line or bar graph pie chart Page 21
