Question | Answer |
Define Science | Natural world; ex: biology=study of living organisms |
Scientific Method=Problem Solving (OHEC) | 1) make OBSERVATIONS 2) form HYPOTHESIS (proposing ideas) 3)EXPERIMENT (testing ideas) 4) form a CONCLUSION (discard/modify ideas based on results) |
Hypothesis (def: proposed explanation for one or more observations) | MUST BE: 1) Testable: possible to evaluate thru measurable universe 2) Falsifiable: potentially false (could be wrong) |
Scientific Theory | *has been tested *based on well supported hypothesis ex: germ theory, theory of evolution, cell theory |
Deductive Reasoning | General to specific *Begin w/ general statement/hypothesis which leads to a specific logical conclusion |
Inductive Reasoning | Specific to general *Logical process that argues from specific instances to general conclusion |
The truth of a hypothesis cannot be proven conclusively via deductive reasoning because: | There may be alternative reasons for the data collected |
Define Variable | Factor of experiment that may CHANGE |
Independent (experimental) variables | *thing you change on purpose; thing you are testing (manipulated by the researcher) |
Dependent (response) variables | *data collecting; thing you are measuring (not changed by the researcher, may change during experiment *observable effects can be measured |
Control in Experimental method | *One independent variable; stay the same *control group needed to compare to *EVERYTHING ELSE REMAINS THE SAME |
Strategies to minimize bias designing experiments | Bias: influence on results Blind Studies: limit participant knowledge Double blind studies: limit researcher knowledge of participant groups |
