Goal To investigate and understand the natural world To explain the events in the natural world Use the explanations to make useful predictions
Scientists To accomplish goal observes gathers data makes inferences logical interpretation based on prior knowledge
PROPOSED scientific explanation Hypothesis PROPOSED scientific explanation testable To help create observations
Always changing with new discoveries, technologies, observations Science NOT a set of truths Always changing with new discoveries, technologies, observations
Scientists Continues to ask questions Forms hypothesis Runs experiments
Control Group Controlled experiment no factors are changed Need to compare it to other factors Factors = variables
Experimental Group Manipulated variables factor that is changed ONE factor for every experiment Independent variable scientists chooses the factor
Experimental Group Responding Variable result of the manipulated variable How does the changed factor affect the experiment Dependent variable
Scientist Record and analyze data Draw a conclusion based on evidence
Science NOT ABSOLUTE TRUTH Adding evidence Refute the current evidence More evidence helps hypothesis become theories
