Physics The study of forces, energy, motion
Chemistry The study of atoms and molecules, their structures, and their interactions to form
substances
Earth science The study of the Earth's structure and composition, and processes that change
Earth
essential attributes of science Studies the natural world
Uses testable ideas
Relies on data from observations/experiments
Presented for evaluation by other scientists
Leads to further questions/research
variables The changing quantities in an experiment
independent variable What you change in an experiment on purpose
dependent variable The variable that changes because of an independent variable
control variable The variable(s) you don't want to study, need to be either eliminated or kept
constant
observational study When systems are observed as they appear in nature, researchers do not
attempt to change them
physical model A model of a physical phenomenon, such as a planetary system
conceptual model A model used to visualize things that cannot be seen, such as atoms
mathematical model A model that treats physical objects/phenomena using mathematical methods
computer model A detailed, complex model calculated by a computer
principle of falsification Principle that only falsifiable statements can be subject to scientific inquiry
hypothesis A testable statement about how something in nature works

law A concise statement that is supported by scientific evidence and repeated
experiments, describes a widespread pattern in nature (what)
theory A statement that explains a wide range of observations, supported by a large
body of scientific evidence (how/why)
meter Base unit of length
kilogram Base unit of mass
second Base unit of time
kelvin Base unit of temperature
Derived units What is produced when the base units/quantities are combined
Speed The name for the distance traveled divided by an interval of time
Volume Term for the amount of space an object occupies
Liquid displacement Method of determining the volume of an object by measuring the amount of liquid
it displaces
direct relationship A relationship between two variables where increasing one increases the other,
and vice versa
