9 This piece of safety equipment is located near the door.

10 The fire extinguisher

11 small amounts of liquid
Equipment used to add small amounts of liquid

12 Medicine dropper

13 Used manually (with your hands) to calculate mass.

14 Triple beam balance

15 Can be used to measure volume.

16 Beakers, graduated cylinders, flasks, etc.

17 Equipment used handle hot or cold glassware.

18 Tongs

19 The first step of the scientific method.

20 State the problem.

21 The step before you form your hypothesis.

22 Background research

23 The step after you form your hypothesis.

24 Test your hypotheis (experiment).

25 The information you collect during an experiment.

26 Data

27 The presentation part of the scientific method.

28 The conclusion.

29 The standard for comparison in an experiment (the normal trial).

30 The control

31 The thing that you change on purpose in an experiment.

32 The independent (manipulated) variable.

33 The things that stay the same in an experiment.

34 The constants

35 Data collected using numbers.

36 Quantitative data

37 The "results" variable of the experiment.

38 Dependent variable

39 The unit for length.

40 The meter

41 This is the best metric unit to describe the mass of a cow.

42 The kilogram

43 This property of an object is measured in liters.

44 The volume

45 This is one of the only countries that still does not use the metric system.

46 The United States of America

47 The length of a soccer field is measured in this unit.

48 Meters

49 Water freezes at this temperature.

50 Zero degrees Celsius

51 This is the measured interval between two events.

52 Time

53 There are 100 of these in a meter.

54 Centimeters

55 To convert from liters to milliliters, you must move this to the right 3 times.

56 The decimal point

57 This system of measurement is used by scientists all over the world.

58 The metric system

59 We drew pictures of this type of data in the gobstopper lab.

60 Qualitative data

61 To check your results, follow this step of the scientific method.

62 Repeat the experiment

63 Results of an experiment are displayed in these.

64 A chart, graph or table.

65 This is the curved surface of a liquid.

66 The meniscus

67 We always put 100mL in the graduated cylinder. This is an example of a ___________.

68 A constant

69 How many meters are in 3 kilometers?

70 Final Jeopardy 3000
