1. Chapter 1 Notes What is Science Video #1

2. I. Science -science comes from the latin word scire “ to know ” Video #2, 3

3. Scientific Theory and Scientific Law (Answer Key) Scientific Theory Scientific Law Both Theory and Law 2) Explains how nature works 1) Biology has more of these 1) Chemistry and Physics have more of these 2) Describes what nature does under certain conditions (usually with a mathematical formula) 1) Tested hypothesis 2) Supported by large amount of data 3) Helps unify a field of study 5) Widely accepted by a vast majority (if not all) scientists within a discipline 4) Can be modified if even 1 peer- reviewed experiment produces data showing disagreement

4. Scientific Theory usually describes a phenomenon seen in nature. Scientific Law usually explains how a process works under a given set of conditions with a mathematical formula. Scientific Theory and Scientific Law BOTH are proven true through continuous experimentation!

5. Mass can come from energy and energy from mass (E= mc 2 ) The speed of light in a vacuum is constant and an absolute physical boundary for motion Is this a scientific theory or a scientific law? Scientific LAW Is this a scientific theory or a scientific law? Part of the THEORY of relativity Question:

6. Is a scientific theory or a scientific law more correct? Trick question! Both are equally proven to be true through continuous experimentation.

7. Video #4 A.Theories and Laws *Theory- describes something observed in nature *Law- explains how a process works (usually an equation involved)

8. B.Scientific Method

9. * a systematic approach to solving a problem (pp13) 1. State the problem 2. Gather information 3. Form hypothesis 4. Perform experiments 5. Record and analyze data 6. State conclusion

10. Scientific Method cont. * hypothesis- educated prediction * Variable(I. & D.)- the one factor that is being tested * Experimental setup- the part that contains the I. variable * Control setup- same as ES, but does not contain the I. variable

11. Scientific Method cont * Data- recorded observations and measurements - in order to become a law, the results must be able to be reproduce many times.

12. Branches of Physical Science pp 6 * Chemistry- study of what substances are made of and how they change and combine * Physics- study of forms of energy and the laws of motion - prefixes

13. II. Scientific Measurements pp 15-19 * Metric System- standard system of science A. Length - basic unit is meter B. Volume - basic unit is liter/ 1ml=1cc C. Mass- basic unit is kilogram

14. Scientific Measurements D. Density- mass/volume E. Temperature- Celsius F. Dimensional Analyst- worksheet

15. III. Tools of Measurement A. Length B. Mass C. Volume D. Temperature
