    • Scientific Method Vocabulary
    • Inference • An assumption based on facts or observations, eventhough it is NOT stated Observations • Information gathered through the 5 senses-seeing, hearing, smelling, tasting, feeling
    • Question/Problem/Purpose • What you are trying to find out • Why the experiment is being done • Usually written in the form of a question
    • Hypothesis or Prediction • What you think will happen • What do you think is the correct answer • a probable solution to the problem based on knowledge you already have
    • Materials • Part of the experiment • a list of supplies or tools that are used during the experiment Procedures • Step-by-step instructions • What you will do to solve the problem • How you will test the hypothesis
    • Data • Information gathered in an experiment • What you will look for during the experiment • Charts, graphs, tables, diagrams
    • Conclusions • A decision based on facts gathered during the experiment • What the results of the experiment tell you about the problem and about your hypothesis
    • Communication or Theory • When scientists (others) repeat an experiment over and over, and the results are similar (or validated), then the hypothesis becomes a theory • Whenever an experiment is repeated and the results are validated, scientists (others) communicate (tell) their results to others
    • Independent Variable • The part of the experiment (factor) that you, the experimenter, change and have control over Dependent Variable • The experimental factor that changes because during or as a result of the experiment, and you did NOT change yourself
    • Constants • Things (factors) that stay the same during the entire experiment so that the dependent variable can be observed
    • Control Group • A group in the experiment that is NOT changed by the experimenter • The group in the experiment that is left alone • The “natural” group
    • Experimental Group • The group in the experiment that is changed by the person conducting the experiment • The group that you work with
