Document Summary
In studying nature, scientists make observations and form and test hypotheses. Inquiry- the search for information and explanations of natural phenomena. Researchers design experiments to minimize potential bias in interpreting results. Apply general principles to predict specific results. Use specific observations to construct general principles. Make predictions about what might occur if the hypothesis is not wrong. Test their predictions by observations, experiments, or both. Hyp 2: the bulb is burned out. The scientific method is an idealized process of inquiry. Hypothesis- based science is based on the textbook scientific method but rarely follows all the ordered steps. Backtracking and rethinking may be necessary part way throughout the process. Basic research is used to extend the boundaries of current knowledge, and provides the scientific foundation used in applied research. Results undergo peer review in scientific journals. A proposed explanation for a natural phenomenon. The body of interconnected concepts, supported by scientific reasoning and experimental evidence.
