20. The study of the processes that take place in organisms.

21. Biochemistry

22. The organized method in which an experiment is done is referred to as the:

23. procedure

24. Deduction, educated guess, idea, possible solution, and prediction are all examples of a(n):

25. hypothesis

26. Independent, dependent, and control are all examples of:

27. variables

28. What are the three parts of an experiment?

29. 1)Procedure 2)Variables 3)Conclusion

30. The part of the experiment which is measured, is a result of the change in the independent variable, and makes up the Y-axis of a graph is called the:

31. dependent variable

32. The part of the experiment which is manipulated by the experimenter and makes up the X-axis of a graph is called the:

33. independent variable

34. The part of the experiment which is held constant and used as a comparison is called the:

35. control variable

36. A fake drug or medication used as a control is an example of the use of a (n):

37. Placebo

38. In order to test an educated guess, one sets up or develops a(n) :

39. Experiment

40. It is important that on records observations and measurements. These records are known as:

41. Data

42. The act of using senses to gather information is called :

43. Observations

44. The experimental factors or what varies in an experiment.

45. Variables

46. The first step in the scientific method is to clearly state the :

47. Problem

48. The general belief and best explanation for natural phenomenon based upon observable facts and experimentation is called a(n) :

49. Theory

50. The idea or educated guess based on patterns of observation.

51. Hypothesis

52. The orderly process gone through by scientists in order to find solutions to problems and to discover answers to questions is known as the:

53. Scientific Method

54. The result or results based on what you have seen as the outcomes of an experiment is called the:

55. Conclusion

56. The statement that if this is true, than this is true is termed a:

57. Deduction

58. List in order and briefly describe the 6 steps of the scientific method. 1 st Step =

66. List in order and briefly describe the 6 steps of the scientific method. 5 th Step =

67. 1) Problem: What is solved 2) Observation: Using your senses 3) Hypothesis: Educated guess 4) Experiment: Test hypothesis *5) Retest/Revise: Redo / Change

68. List in order and briefly describe the 6 steps of the scientific method. 6 th Step =

69. 1) Problem: What is solved 2) Observation: Using your senses 3) Hypothesis: Educated guess 4) Experiment: Test hypothesis 5) Retest/Revise: Redo / Change *6) Theory: Hypothesis that withstands repeated testing, Final and best explanation

70. The following statements are examples of the use of the Scientific Method. What is the correct step? Heat on the bottom glass tube causes the air to expand, the liquid to rise, and the birds head to dip into the water. The moist tip makes the top of the “bird” cooler and keeps the liquid rising.

71. Theory

72. The following statements are examples of the use of the Scientific Method. What is the correct step? I redid my experiment using a control and another cylinder and changed my procedure by adding food coloring to the liquids.

73. Retest / Revise

74. The following statements are examples of the use of the Scientific Method. What is the correct step? I think there was something other than water in the cylinders. I predict the mystery liquid will be less dense than water.

75. Hypothesis

76. The following statements are examples of the use of the Scientific Method. What is the correct step? There were three graduated cylinders filled with liquid. In the first cylinder the ice floated, in the second the ice sank, and in the third the ice stayed in the middle.

77. Observations

78. The following statements are examples of the use of the Scientific Method. What is the correct step? To test my prediction I heated the bottom of the “birds” and pulse glass with the heat of my hand and observed the results.

79. Experiment

80. The following statements are examples of the use of the Scientific Method. What is the correct step? What makes the bird move, and why doesn’t the ice float?
