Document Summary

Scientific method: gather data via observations/experiments identify patterns / trends in the collection data summarize their findings with a law formulate a hypothesis with time a hypothesis may evolve into a theory. 1. 2: classification of matter substance: a form of matter that has definite composition and distinct properties e. g. : salt, iron, water, mercury, carbon dioxide, oxygen. Can tell the difference by appearance smell taste and other properties. Mixture: solid: held close together, rigid liquid: particles not as close, form shape of container but not volume gases: significantly separated, take shape and volume. Classification of matter: sublimation mixture can be separated by physical means into its components. Quantitive: properties that can be measured a measured quantity must always include a unit english system: foot, gallon, pound metric system: meter, liter, kilogram. 7 si base units: length,meter mass, kilogram time, second electric current, ampere temp, kelvin amount of substance, mile prefixes: pico to tera.
