Document Summary
Science aims to understand the natural world through observation and reasoning. Science is in a constant state of change as new data, new methods, and new ideas arise. Uses both deductive and inductive reasoning: deductive reasoning uses general principles to make specific. Natural selection is used to explain changes in: inductive reasoning uses specific observations to develop predictions populations. general conclusions. Fossils show that life has changed on the earth over time. Science begins with observations, therefore much of science is purely descriptive: ex. Classifying and describing life in a given habitat or genomic sequencing. A systematic approach to understanding the natural world: the (cid:1) (cid:1) (cid:1) (cid:1) Should make a prediction that can be tested. May be revised in light of new data: prediction, experimentation. Must be carefully designed to test only one variable at a time (this is the independent variable) Consists of a control and a test experiment. Test experiment independent variable is changed.
