1 KEY CONCEPT Science is a way of thinking, questioning, and gathering evidence.
2 Scientific Method-Define words underlined Inquire, question, wonder, recognize, research a problemObserveForm Hypothesis-a statement that can be testedExperiment (dependent variable and independent variable-control) ConstantsRecord data ( qualitative-descriptive-observations) and (quantitative)Analyze dataDraw conclusionsCompare and validate (verify)Form a TheoryEstablish a Law
3 Like all science, biology is a process of inquiry. Observing- using the senses or tools to gather informationdata -recorded observations
4 hypotheses- ask a question and try to explain observation experiments - test of the hypothesis, collect data to support or reject a hypothesis
5 Analyzing data- to draw conclusions Evaluating results data and conclusions are studied to determine validity
6 Experiments – a test of the hypothsie that uses variables of find cause and effect relationships Independent variables –the conditions that are manipulated.- the “cause”Dependent variables -the factor that is observed and measured – the effect.Constants are conditions that are kept the same.
7 A theory –a proposed explantion for a wide range of observation and results that is supported by a wide range of observations.Theories can change based on new evidence.
