Document Summary
Scientific method: observation, generalization or model, predictions or hypothesis, test, science is a cyclic process, constant observing and gathering of information to refine explanations, theories vs. Sharing of a group of characteristics not found in non living things: non-living things can have characteristics shared among living things, just not all of those characteristics. Living things go through process of development (birth-death) Looks at interactions among large scale phenomena: ex. Hydrogen has 1 proton and 1 electron in the outer shell so. Form when atoms completely gain or lose electrons (forming an ion) Strongest bonds when dry (not interacting with water: ex. Salt crystal is hard out of water, dissolves in water. Sodium has an atomic # of 11 so it has 1 electron in the outer shell; valence = 1: chlorine has an atomic # of 17 so it has 7 electrons in the outer shell; valence.
