Studying the effect of one thing on another in order to test a hypothesis is a(n) \_\_\_\_.
experiment
23
A factor that is manipulated in an experiment to change the dependent variable
independent varialble (aka manipulated variable)
24
"aka" means
also known as
25
"also known as" is often abbreiviated as:
aka
26
milli-
SI prefix meaning 0.001
27
kilo-
SI prefix meaning 1,000
28
centi-
SI prefix meaning 0.01
29
mass
amount of material in an object
30
kelvin
SI unit of temperature
31
second
SI unit of time
32
kilogram
SI unit of mass
33
cubic centimeter
derived unit of volume | (its a cube with 1 cm sides)
34
micro
SI prefix meaning one millionth of (x 10e-6)
35
nano
SI prefix meaning one billionth of (x 10e-9)
36
Mega
SI prefix meaning one million of (x 10e6)
37
Mnemonic device for remembering SI prefixes
Mr. King Henry Died By Drinking Chocolate Milk Mix Nuggets
40
meter
SI unit of length
41
dependent variable is usually plotted on the
vertical or y-axis
42
SI
worldwide system of measurement (**_S_**ysteme **_I_**nternational d'unites)
43
dependent variable is aka
responding variable (IM DR)
44
independent variable is aka
manipulated variable (IM DR)
45
"IM DR" is a mnemonic device to help remember
(Independent variable = Manipulated variable) and (Dependent variable = Responding Variable)
46
Precision
How closely measurements are too each other.
47
Accuracy
How close a measurement is to the true value or even the accepted value.
48
True value
The result you would get if you could actually make a perfect measurement. (Too bad you can never do that. It is impossible)
49
Mr.
mega (x 10e6) (M)
50
King
kilo (x 10e3) ( k)
51
Henry
hecto (x 10e2) (h)
52
Died
deka unit (x 10e1) (dk)
53
By
\_\_\_\_\_\_(x 10e0) (no prefix because this is the base unit like grams, meters, liters, etc)
54
Drinking
deci (x 10e-1) (d)
55
Chocolate
centi (x 10e-2) (c )
56
Milk
milli (x 10e-3) (m)
57
Mix

(x 10e-9)
59
m
The greek letter "mu" (pronounced "mew" like a cat might say)
60
Temperature of absolute zero in kelvin
0 degrees Kelvin
61
Temperature of absolute zero in Celsius
negative 273 degrees celsius
62
Temperature of absolute zero in Fahrenheit
negative 459.4 (don't memorize this, just know that it is really, really cold)
63
Why don't we draw lines between bars on a bar graph?
There is no data between the bars on a bar graph.
64
Why do we draw lines between ponts on a line graph?
To represent the expected values of the unmeasured data between the measured points.
65
Why do we typically avoid putting "breaks" in the axes of graphs?
It distorts the appearance of the data.
66
When do we put "breaks" in the axes of graphs?
When we are willing to live with the distorted appearance of the data so that we can zoom in on a specific region of the data.
67
Scientific experiments investigate the effect of one ___________ on another.
variable
68
Any SI unit can be converted to any other SI unit by multiplying by the appropriate ___________ \_\_\_\_\_\_\_\_\_\_\_\_\_.
conversion factor
69
Graphs are visual representations of data that help scientists to detect _________ in the data.
patterns

74
qualitative observation
has **no** numbers
75
quantitative observations
has numbers
76
Must be in the form of a statement.
A hypothesis
77
What punctuation mark can NEVER follow a hypothesis?
A question mark (A hypothesis is a statement, it is never a question)
78
79
You read something and recognize that it is a STATEMENT of how nature behaves. Is it a Scientific Law or Scientific Theory?
**Scientific Law** Scientific Laws are **_statements_** of how nature behaves.
80
You read something and recognize that it is an EXPLANATION of how nature behaves. Is it a Scientific Law or Scientific Theory?
**Scientific Theory** Scientific Theories are **_explanations_** of how nature behaves.
