8. State the three basic units of the metric system and what they measure 7.Length? 8.Mass? 9.Volume? METER GRAM LITER

9. Understand that the metric system units are based on powers of 10, and we use different prefixes to reflect those units 10. 11. 12. KILO CENTI MILLI

10. Convert metric units using decimal movements (aka “The Ladder Method” 13. 1700m = _______ cm 14. 50mg = ________ g 15. 78L = _________ mL 170000.050 78000

11. 16. Explain why the metric system is easier to use than standard/English units TO CONVERT, YOU ONLY HAVE TO MOVE THE DECIMAL POINT, AS THE UNITS ARE ALL BASED ON POWERS OF 10.

16. Place the independent variable and dependent variable of an experiment on the proper axes of a bar graph or line graph 21. 22. DEPENDENT VARIABLE INDEPENDENT VARIABLE

17. Recognize different types of data collected in an experiment 23.The sponge emerged from its capsule from one side first. 24.The capsule was sticky. 25.The red capsule emerged first, with an average time of 58 seconds. 26. QUALITATIVE QUANTITATIVE

18. Formulate a hypothesis based on a given set of observations 27. What was the hypothesis? THE ENERGY DRINK INCREASES THE PRODUCTIVITY OF WORKERS

19. Distinguish between an independent and dependent variable 28.What is the independent variable? 29.What is the dependent variable? ENERGY DRINK STACKS OF STAPLED PAPER

22. Distinguish between a hypothesis and an opinion 33.Chipotle is better than Hot Head. 33.Windex prevents streaking of glass better than other glass cleaners. 35. Mrs. Harlow is the best science teacher ever. OPINION HYPOTHESIS OPINION

23. Understand that scientific findings should be reviewed by other scientists before they are published and that sharing these findings help to advance science 36. Who reviews articles for peer-reviewed journals? a.friends of the scientists who wrote the articles b.anonymous and independent experts c.the scientists who did the experiments d.people who paid for the experiments

24. Understand that scientific findings should be reviewed by other scientists before they are published and that sharing these findings help to advance science 37. How does sharing ideas through peer-reviewed articles help advance science? a.Peer-reviewed articles are published only when the ideas they contain have been accepted by most scientists. b.Experiments in peer-reviewed articles do not need to be repeated. c.Scientists reading the articles may come up with new questions to study. d.Ideas in the articles always support and strengthen dominant theories.

25. Understand that scientific findings should be reviewed by other scientists before they are published and that sharing these findings help to advance science 38. A scientist discovers an important breakthrough in cancer treatment. The scientist thinks the information could save thousands of lives and immediately announces the results on national television, skipping peer review. How might other scientists react to this news? a.They will be skeptical because the report was not peer-reviewed. b.They will quickly start to use the new treatment on their patients. c.They will congratulate the scientist for the discovery. d.They will denounce the work and call the scientist a fraud.

26. Identify questions that can be answered by science 39.What color is the most beautiful? 40.How does acid rain affect plant life? 41.Do people go out to eat too much? NO YES NO

27. 42. Recognize when an experiment is unethical AND explain why A strange nerve disease attacked the people on an island. Symptoms of the disease included weakness and loss of appetite; victims often died of heart failure. Scientists thought the disease might be caused by bacteria. They injected healthy island inhabitants with bacteria from the blood of the sick patients. The injected people also became sick. IT CAUSES HARM TO HUMAN LIFE
