scientific method
observation, hypothesis, experiment, theory, law
law
predicts what happens
theory
explain why it happens
experiments
the testing of a hypothesis under controlled conditions
matter
Anything that has mass and takes up space
chemical properties
determine how a substance can be converted into another substance
physical properties
Can be observed or measured without changing the identity of the matter
solid state
definite value, maintains shape, particles lie close together in a regular pattern
liquid state
definite volume, shape of container, close together but can move past one another
gas state
no definite volume or shape, particles are very far apart and move around randomly
