Document Summary

Chemistry: the study of composition, properties and interactions of matter. Hypothesis: a tentative explanation of observations that acts as a guide for gathering and checking info. Theories: well-substantiated, comprehensive, testable explanations of particular aspects of nature. Can be modified with discovery of new data. Macroscopic domain: things that are large enough to be sensed by human sight or touch, can observe & measure physical and chemical properties. Microscopic domain: some aspects are visible through microscopic, most are too small to be seen, ex. Atoms, ions, electrons, protons, neutrons, chemical bonds. Conversion of nutrient molecules into tissue and energy. Symbolic domain: specialized language used to represent components of the macroscopic & microscopic domains, help interpret behavior of macroscopic domain in terms of components of microscopic domain, ex. Macroscopic domain: melting, freezing, and evaporations of water. Microscopic domain: molecule of water as 2 hydrogens and one oxygen (structure)
