Document Summary
The process of science: goal of science. Establish cause and effect relationships: ex. If you dam this creek trout will not reproduce. Make models that explain the natural world: weather. Applied science: produce useful products, science is a process used to explain natural events. Laws, principles and rules: developed to explain nature. Scientists use two main approaches to learn about nature: discovery science. In discovery science: scientists describe some aspect of the world and use inductive reasoning to draw general conclusions, hypothesis-based science. In hypothesis based science: scientists attempt to explain observations by testing hypotheses. With hypothesis-based science, we pose and test hypotheses. Observations, questions, hypotheses as tentative answers to questions. Deductions leading to predictions, and then tests of predictions to see if a hypothesis is falsifiable. The procedures that scientists must use to arrive at valid conclusions. Separates scientific fields of study from all others: observation. Be creative- a new approach: hypothesis formation.
