14	What is Chemistry? Chemistry is the science of the properties, composition, and behavior of materials. Chemistry is the science concerned with describing and explaining the different forms of matter and the chemical reactions or matter.
15	Branches of Chemistry Applied Chemistry - the search for and isolation of useful materials. Theoretical Chemistry - Provides a chemical view of nature and explanations of natural processes.
16	Chemistry is the Central Science
17	Scientific Method Observation – a statement that accurately describes something we see, hear, taste, feel, or smell. Conclusion – a statement that is based on what we think about a series of observations.
18	"Before fermentation" Before fermentation, grape juice is very sweet and contains no alcohol. After fermentation, the grape juice is no longer as sweet and it contains a great deal of alcohol. In fermentation, sugar is converted into alcohol.
19	"During fermentation" During fermentation, bubbles of a colorless, odorless gas form in the grape juice. In fermentation, sugar is converted into alcohol and a colorless gas.
20	From Scientific Method Laws - observations that are consistent Theories or Models - unifying explanation for a set of observations, facts, and laws
21	"Empirical facts" Empirical facts (observations, data) Scientific laws (tested generalizations) Hypothesis (tentative explanation) Theory (tested explanation)
