to form substances
Earth science - correct answer ✔The study of the Earth's structure and composition, and processes that
change Earth
essential attributes of science - correct answer ✔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 - correct answer ✔The changing quantities in an experiment
independent variable - correct answer ✔What you change in an experiment on purpose
dependent variable - correct answer ✔The variable that changes because of an independent variable
control variable - correct answer ✔The variable(s) you don't want to study, need to be either
eliminated or kept constant
,observational study - correct answer ✔When systems are observed as they appear in nature,
researchers do not attempt to change them
physical model - correct answer ✔A model of a physical phenomenon, such as a planetary system
conceptual model - correct answer ✔A model used to visualize things that cannot be seen, such as
atoms
mathematical model - correct answer ✔A model that treats physical objects/phenomena using
mathematical methods
computer model - correct answer ✔A detailed, complex model calculated by a computer
principle of falsification - correct answer ✔Principle that only falsifiable statements can be subject to
scientific inquiry
hypothesis - correct answer ✔A testable statement about how something in nature works
law - correct answer ✔A concise statement that is supported by scientific evidence and repeated
experiments, describes a widespread pattern in nature (what)
theory - correct answer ✔A statement that explains a wide range of observations, supported by a large
body of scientific evidence (how/why)
meter - correct answer ✔Base unit of length
