What is chemistry? Study of matter, energy, and their interactions What is matter? Anything that occupies space… What isn’t matter? Light, ideas, electricity…

Some Science Terminology scientific fact – specific, verifiable information *Sulfur is a yellow mineral. *Granite is an igneous rock. hypothesis – possible action and/or explanation for a behavior or an observation; must be tested through experimentation *Magnetism is based on electron associations

Some Science Terminology law - generalized statement of a relationship between variables in a system based on repeated experimentation; can be used to predict behavior of a system *As the temperature of a gas increases, its volume increases. theory - generalized explanation for observations based on repeated experimentation or observations *Gas behavior such as expansion with heat or increased pressure with decreasing volume is a result of particles that are far apart and moving rapidly

Some Science Terminology scientific beliefsomething that is accepted as true based on scientific evidence but cannot be proven at that time *All protons are identical *The sun will rise tomorrow.

Scientific Method (idealized) Make an observation that generates a question. Form a testable hypothesis that addresses the question. Design and conduct an experiment to prove or disprove the hypothesis. Analyze the data. Form a conclusion about the hypothesis.
