Lab 2: the scientific method: discovery science - uses large amounts of data or surveys natural systems to discover patterns and correlations i. Using biochemical techniques to identify molecules in cells and find that certain proteins are found in muscle cells but not neurons: hypothesis driven science - uses the scientific method i. ii. iii. iv. v. vi. vii. Collection of background information - scientific journals, books, maps. Hypothesis - uses inductive reasoning (specific to general observation: hypotheses can never be proven. State predictions - if/then statements; use deductive reasoning (general to specific) Drawing conclusions - use statistics to determine accuracy of results. Reporting conclusions: experimental design i. ii. iii. iv. v. Dependent variable - responds to changes in the independent variable. Controlled variables - factors that can affect the dependent variable that must be kept constant or controlled. Control group - independent variable is either not included or kept constant in natural state: types of data i. ii.
