12
The scientific method is a logical process to _______ a _________.

13
Solve a problem

14
After you state or identify the problem and before you form your hypothesis, you must do what?

15
Gather Information by Researching the problem

16
The third step of the scientific method is ________

17
hypothesis

18
Used to set what is “normal” from which comparisons can be made

19
The control group

20
This occurs each time an experiment is run and needs to be a high # to add credibility to the work.

21
A trial

22
What is the x-axis most closely related to?

23
The independent variable

24
This variable answers the questions “What do I change?” in an experiment.

25
Independent variable

26
On this graph, the dependent variable is:

27
Speed (m/sec)

28
This variable answers the question “What do I observe?” in the experiment.

29
Dependent variable

30
The cube fell quickly through layer A, fell slowly through layer B, and stopped upon reaching layer C. The density of the cube most likely lies between A, B, C or D. A and 1.50 g/cm 3. B and 3.50 g/cm 3. C and 6.00 g/cm 3. D and 9.00 g/cm 3 A solid cube was put into a cylinder containing four liquids with different densities as shown below.

31
C and 6.00 g/cm 3

32
What does this instrument measure?

33
mass

34
The curved shape of the water is called the _________?

35
meniscus

36
What measurement is being recorded on this marble?

37
volume

38
If you calculate the volume by using the formula V = l x w x h What measuring instrument did you use to gather the data?

39
A ruler

40
What is the measurement of the black object in the illustration above?

41
2.6 centimeters

42
How many seconds are in one day?

43
86,400 s 1 day 24 hr 60 mins 60 sec 1 day 1 hour 1 min 1 x 24 x 60 x 60 = 86,400 s

44
A woman jogs for 2.0 hours covering a distance of 13 kilometers. What is the speed of the woman expressed in kilometers per hour?

45
d = 13 km t = 2.0 hr s = ? s = d / t s = 13 km/2.0 hr s = 6.5 km/hr

46
If an automobile travels at 30 m/s for 2 mins., how many meters does it travel?

47
d = ? t = 2 mins = 120 s s = 30 m/s d = s x t d = 30 m/s x 120 s d = 3600 m

48
In one-half hour, a bicyclist traveled 20 km. What was the bicyclist’s speed?

49
d = 20 km t = 0.5 hr s = ? s = d / t s = 20 km / 0.5 hr s = 40 km/hr

50
If you traveled 225 km at 75 km/hr, how long did you travel?

51
d = 225 km t = ? s = 75 km/hr t = d / s t = 225 km / 75 km/hr t = 3 hr
