well as thethat change Earth, such as volcanic and seismic
processes
activity.

other objects in
spac
e
Science ( Correct answers ) An organized way of gathering and
analyzing
about the evidence
natural
world.
Precision ( Correct answers ) a measure of how close a series of
measurements
to one are
another
SI ( Correct answers ) is a scientific method of expressing the
magnitudes
quantities ofor
important natural phenomena. There are seven base units in
the system,
from which other units are derived. Universal for
comparing data.
physical science ( Correct answers ) the sciences concerned with
the study of
inanimate natural objects, including physics, chemistry, astronomy,
and related
subject
s.
life science ( Correct answers ) the study of
living things
controlled experiment ( Correct answers ) An experiment in which only one
variable is at a time. Or a condition that is being
manipulated
held constant
independent variable ( Correct answers ) what is being
changed
dependent variable ( Correct answers ) what is being
measured
control ( Correct answers ) In an experiment, the standard that is used for
comparison
ALREADY
GRADED A+
,Observational experiment or study ( Correct answers ) studies attempt to
cause-and-effect relationships. However, unlike experiments, the
understand
researcher
able to control
is not
(1) how subjects are assigned to groups and/or (2) which
treatments
each group receives. ... Therefore, a sample survey is an example of an
study.
observational
field study ( Correct answers ) a research investigation carried out in
a naturally occurring setting
laboratory study ( Correct answers ) Research done in a
laboratory
Physical Model ( Correct answers ) A physical representation of an object.
Prototypes and appearance models are physical models.
conceptual model ( Correct answers ) a verbal or graphical explanation
for how a system works or is organized
mathematical model ( Correct answers ) one or more equations that
represent the way a system or process works
Hypothesis ( Correct answers ) A testable prediction, often implied
by a theory
Theory ( Correct answers ) A hypothesis that has been tested with a
significant amount of data. Explains why something happened.
Law ( Correct answers ) A law in science is a generalized rule to explain
a body of observations in the form of a verbal or mathematical
statement. Scientific laws (also known as natural laws) imply a cause and
effect between the observed elements and must always apply under the
same conditions. Explains how it happened not why.
Observation ( Correct answers ) Information obtained through
the senses.
evidence ( Correct answers )
proof
Data ( Correct answers ) Facts and statistics collected together for
reference or analysis
Big Bang Theory ( Correct answers ) Cosmological model that explains
the sudden development of the universe through expansion from a hot,
dense state.
plate tectonics ( Correct answers ) A theory stating that the earth's
surface is broken into plates that move.
ALREADY
GRADED A+
, atomic theory ( Correct answers ) a theory that states that all matter is
composed of tiny particles called atoms.
gram ( Correct answers ) a metric unit of mass equal to one thousandth of
a kilogram.
meter ( Correct answers ) The meter is the basic unit of length in the
SI system
units. ... The
of previous definition of the meter was one ten-millionth of the
distance
the geographic
from north pole to the equator, measured over the earth's
surface in
running through
a circle
Paris,
France.
second ( Correct answers ) SI base unit
for time
Celsius ( Correct answers ) Metric unit for measuring temperature; On
this scale water freezes at zero and boils at 100.
Kelvin ( Correct answers ) The SI base unit of
temperature
liter ( Correct answers ) Basic unit of volume in the
metric system
Metric Prefixes ( Correct answers ) Giga, Mega, Kilo, deci, centi, milli,
micro, nano
derived unit ( Correct answers ) A unit defined by a combination of
base units
direct relationship ( Correct answers ) a relationship in which one variable
increases with an increase in another variable
inverse relationship ( Correct answers ) a relationship in which one
variable decreases when another variable increases
Speed ( Correct answers ) The distance an object travels per
unit of time
Velocity ( Correct answers ) Speed in a given
direction
Acceleration ( Correct answers ) the rate at which velocity changes
over time; an object accelerates if its speed, direction, or both change
distance ( Correct answers ) The length of a path between
two points
Displacement ( Correct answers ) Distance and direction of an object's
change in position from the starting point.
Balance force ( Correct answers ) Equal forces acting on one object in
opposite direction. These forces then give a 0 net force, causing the
object to stay in place.
