1 Test Review : Chapter 1 Scientific Method Chemistry

2 Scientific Method

3 Conclusion

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

5 control variable

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

7 Data

8 It is important that one records observations and measurements. These records are known as:

9 dependent variable

10 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:

11 Experiment

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

13 What are the three parts of an experiment?

14 1)Procedure

15 1)Procedure 2)Variables

16 1)Procedure 2)Variables 3)Conclusion

17 Hypothesis

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

19 Other names for hypothesis?

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

21 independent variable

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

23 Observations

24 The act of using senses to gather information is called :

25 Placebo

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

27 Problem

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

29 procedure

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

31 Retest

32 The experiment must always work under the given conditions. Redo it over and over for correct results

33 Revise

34 If experiment does not work then changes are made. Change the hypothesis, procedure, or go back and make more observations and change what is to be solved

35 Scientific Method

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

37 Theory

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

39 Variables

40 The experimental factors or what varies in an experiment.

41 3 Types of variables?

42 Independent, dependent, and control are all examples of:

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

44 1) Problem: What is solved

45 List in order and briefly describe the 6 steps of the scientific method. 2 nd Step =

46 1) Problem: What is solved *2) Observation: Using your senses

47 List in order and briefly describe the 6 steps of the scientific method. 3rd Step =

48 1) Problem: What is solved 2) Observation: Using your senses *3) Hypothesis: Educated guess

49 List in order and briefly describe the 6 steps of the scientific method. 4 th Step =

50 1) Problem: What is solved 2) Observation: Using your senses 3) Hypothesis: Educated guess *4) Experiment: Test hypothesis

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

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

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

54 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

55 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.

56 Theory

57 The following statements are examples of the use of the Scientific Method. What is the correct step? I redid my experiment several times using different cups and later changed my procedure by adding salt to the cups.

58 Retest / Revise

59 The following statements are examples of the use of the Scientific Method. What is the correct step? I think there was something in the cup that made the water disappear.

60 Hypothesis

61 The following statements are examples of the use of the Scientific Method. What is the correct step? There was a beaker of water and three red cups. The water was poured in the three cups and on the third trial it disappeared.

62 Observations

63 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.

64 Experiment

65 The following statements are examples of the use of the Scientific Method. What is the correct step? What makes the bird move, and what happened to the water?

66 Problem

67 The following statements are examples of the use of the Scientific Method. What is the correct step? Step 1) Redo the first experiment Step 2) Replace the red cups with clear cups Step 3) Pour water into each cup Step 4) Turn cup upside down and record results
