testable question
can be answered through experimental inquiry and observation of the natural world
Quantitative
quantity
Non-testable question
a question in which you cannot test
Qualitative
quality
Trials
test runs
Observation
watching something to gain info
Empirical evidence
information obtained through observation and documentation
Data
facts and statistics collected together for reference or analysis.
Model is science
a physical repersentation of events
Analogy
a comparison between two things,
prototype
a first, typical or preliminary model of something,
Hypothesis
a guess or idea
Variable
not consistent
Procedure
an established or official way of doing something.
Precision
the quality, condition, or fact of being exact and accurate.
Accuracy
the quality or state of being correct or precise.
Scientific method
a method of procedure that has characterized natural science
Control
the power to influence or direct people’s behavior or the course of events.
Constant
always
Predict
say or estimate that something will happen
Infer
deduce or conclude
Independent variable
a variable (often denoted by x ) whose variation does not depend on that of another
Dependent variable
a variable (often denoted by y ) whose value depends on that of another.
Manipulated variable
A manipulated variable is the independent variable in an experiment
Responding variable
the part of an experiment that a scientists measures and observes closely for a change or a response
Sample size
the act of choosing the number of observations or replicates to include in a statistical sample.
Validity
the quality of being logically or factually sound; soundness or cogency.
Trends in data
the general change in a variable with time
Correlation
a mutual or reciprocal relationship between two or more things
Variability
the tendency to shift or change of being “variable.”
Mass
a measurement that refers to the amount of matter that makes up an object.
Volume
the amount of space that a substance or object occupies,
Weight
relative heaviness
Percent

Rate
a measure, quantity, or frequency, typically one measured against some other quantity or measure.
Ratio
the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
Line graph
a graph that uses lines to connect individual data point
Bar graph
a diagram in which the numerical values of variables are represented by the height or length of lines
Pie graph
a type of graph representing data in a circular form,
scatter plot
uses dots to represent values for two different numeric variables
Claim
state or assert that something is the case, typically without providing evidence or proof
Evidence
the available body of facts or information indicating whether a belief or proposition is true or valid
Reason
a cause, explanation, or justification for an action or event.
Theory
