law
a descriptive statement or equation that reliably predicts events under certain conditions
Theory
a system of ideas that explains many related observations and is supported by a large body of evidence acquired through scientific investigation
qualitative statement
describes something with words
quantitative
describes something with mathematical equations
Model
a representation of an object or event that can be studied to understand the real object or event
scientific method
a series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions
controlled experiment
an experiment in which the variables that could affect the experiment are kept constant (controlled) except for the one that you want to measure
variable
a factor that changes in an experiment in order to test a hypothesis
length
a measure of the straight-line distance between two points
mass
amount of matter in an object
volume
a measure of the size of a body or region in
three-dimensional space
weight
a measure of the gravitational force exerted on an object
dependent variable
values depend on what happens in the experiment
independent variable
values are set before the experiment takes place
accuracy
a description of how close a measurement is to the true value of the quantity measured
precision
the exactness of a measurement
