Document Summary
What do scientists do: make observations, attempt to discern patterns, assume that the future is like the past. Scientific method: observation, generalization or model, predictive statements or hypothesis, tests back to observations, outcome: a better understanding of science. What is life: requires o2 (gas exchange, reproduction/development, evolves/adaptable, responds to environment, organic matter, **organization, **energy use. Scale of nature: what scales are biologists interested in, atomic 10-8 meters, community/ecosystem 106 meters. Approaches to biology: reductionist, try to isolate and control variables to figure out how one thing works at a time. Add them up together to figure out how the whole thing works: holist, study interactions between multiple factors and how it affects them. Solubility: what determines solubility, like dissolves like, like in terms of polarity. 9/14/2013 7:54:00 pm: polar solutes dissolve in polar solvents, non-polar solutes dissolve in non-polar solvents. **atomic structure questions: protons and ____ are located in the nucleus of an atom, with ____ orbiting the nucleus.
