  1. Scientific Method Review Are you ready for your test?

  2. Q1 • The step of the Scientific Method that is in a question format. • Answer: PROBLEM

  3. Q2 • A testable statement in the scientific method • Answer: HYPOTHESIS

  4. Q3 • The part of the scientific method that allows us to test the hypothesis. • Answer: EXPERIMENT

  5. Q4 • The group that the experiment is performed on. • Answer: EXPERIMENTAL GROUP

  6. Q5 • The group that the results are compared to and it receives no experimental treatment. • Answer: CONTROL GROUP

  7. Q6 • The variable changed by the scientist and it is what the scientist is testing in the experiment. • Answer: INDEPENDENT VARIABLE

  8. Q7 • Data used to make graphs, gained from counts or measurements and it is numerical. • Answer: QUANTITATIVE DATA

  9. Q8 • The variable that is measured or observed throughout the experiment. • Answer: DEPENDENT VARIABLE

  10. Q9 • The axis where the independent variable is placed. • Answer: X-AXIS

  11. Q10 • A concise statement above the graph that tells the reader what the graph is about. • Answer: TITLE

  12. Q11 • Should include all data points and climb in intervals such as multiples of 2, 5, 10, etc. • Answer: SCALE

  13. Q12 • The axis where the dependent variable is located. • Answer: Y-AXIS

  14. Q13 • A short description concerning the graph’s data. • Answer: LEGEND

  15. Q14 • The type of graph that best shows the relationship between two variables. The data is continuous. • Answer: LINE GRAPH

  16. Q15 • Type of graph that has labels rather than numbers on the x-axis. The data is not continuous. • Answer: BAR GRAPH

  17. Q16 • A graphs that shows the data as a percentage in relation to the total data. • Answer: CIRCLE GRAPH

  18. Q17 • The part of a lab report contains the title of the experiment, your name, all of your lab partner’s names, experiment dates, class and hour. • Answer: TITLE/COVER PAGE

  19. Q18 • This section of the lab report contains the independent variable, dependent variable, and controls. • Answer: EXPERIMENTAL DESIGN

  20. Q19 • The section of the lab report explains any mistakes you made during the lab. • Answer: SOURCES OF ERROR

  21. Q20 • This section of the lab report tells what happened in the lab and why. • Answer: ANALYSIS

  22. Q21 • The section of the lab report where you reject or accept your hypothesis. • Answer: CONCLUSION

  23. Q22 • Mr. Orange, Mr. Blue, and Mrs. Purple all had weeds growing in their yards. Mr. Orange does nothing about his weeds. Mr. Blue applies weed killer X. Mrs. Purple applies weed killer T. What is a good problem for this scenario? • Answer: WHICH WEED KILLER IS GOING TO KILL THE MOST WEEDS?

  24. Q22 • Based on the weeds scenario, what is the hypothesis? • Answer: IF BRAND X WEED KILLER IS APPLIED TO A LAWN THEN IT WILL HAVE LESS WEEDS THAN A LAWN TREATED WITH BRAND T WEED KILLER

  25. Q24 • What is the control group in the weed killer experiment? • Answer: MR. ORANGE’S LAWN WITH NOTHING APPLIED

  26. Q25 • What is the experimental group in the weed killer experiment? • Answer: MR. BLUE’S LAWN & MRS. PURPLE’S LAWN BECAUSE THEY BOTH HAD SOME SORT OF WEED KILLER

  27. Q26 • What is the independent variable in the weed killer experiment? • Answer: THE WEED KILLER BRAND X OR T

  28. Q27 • What is the dependent variable in the weed killer experiment? • Answer: THE AMOUNT OF WEED KILLER IN EACH LAWN

  29. Q28 • Is the weed killer experiment done in a controlled environment? • Answer: NO, BECAUSE IT IS OUTSIDE, NOT IN A LAB

  30. Q29 • The common steps that biologists and other scientists use to gather information and answer questions. • Answer: SCIENTIFIC METHOD

  31. Q30 • Jack and Jill collected the following data: green, strong, dark, and many ears of corn. What kind of data is this? • Answer: QUALITATIVE

  32. Q31 • Name the Safety Symbol

  43. Q42 • What does this measure? • mass

  44. Q43 • What were the three safety precautions for the blue lab? • Eye safety (goggles) • Clothing protection (aprons) • Chemical (careful of spills)

  45. Q44 • In the Blue lab why did the liquid change to blue only when half the flask was full? • Air/oxygen

  46. Q45 • What were you trying to determine during the blue lab? (What was the problem?) • Are liquids A and B the same?

  47. Q46 • While conducting the blue lab why did you perform three trials for each flask in experiment 3? • More valid/reliable
