III. Physical Science
study of study of mattermatter and and energyenergy
A. Chemistry – study of substances (matter) and their reactions with other substances.
B. Physics – study of the properties, changes, and behavior of matter and energy.

C. Definitions1. 1. mattermatter – anything that occupies space and – anything that occupies space and has masshas mass
ex: solid, liquid, gas
2. energy – the ability of an object to move or to move something
ex: heat, electricity, sound, light3. property – description of an object and
how it behaves

IV. Scientific Method-A way of solving a problem, answering a
question, or testing an ideaA. Problem – idea to be tested or question to be answeredB. Collect information/ RESEARCH – ask someone, read, internet, observe, measure with instrumentsC. Hypothesis – possible guess to a problem

D. Experiment – test of a hypothesis using
organized steps 1. variable – factor being tested CHANGE
2. control – factor not being tested SAME
E. Record/Analyze Results – write down and graph information.
F. Conclusion – answer to hypothesis
1. qualitative data – information that describes an objects physical characteristics or properties
2. quantitative data – numerical information Data tables and graphs

V. DefinitionsA. Theory – a tentative explanation for how
something behaves
ex: cell theory, atomic theory
B. Law – statement that describes how something behaves. may be a theory that has been proven to be true several times. Does not explain why. ex: gravity
