  • 1. 7 th Grade: Chapter 1 Lesson 1 Scientific Method Pgs. 3-8 For student use only
  • 2. Scientific Method
    • Purpose of Science:
      • To observe nature and discover the laws of creation so that they can be put to the benefit of mankind.
    • How do we observe nature?
      • We ask questions and do experiments!
  • 3. Scientific Method
    • In this chapter we will use the Scientific Method to study pedology (the study of soil).
    • Francis Bacon was one of the founders of modern science and introduced the scientific method of studying nature.
  • 4. Scientific Method
    • Scientific Method: a systematic way that scientists gather and pursue scientific knowledge.
    • Three main parts of Scientific Method:
      • Observation- gathering data (using what you know)
      • Hypothesizing- educated guess
      • Experimentation- methodical testing of hypothesis
  • 5. Scientific Method
    • Scientific Method: 6 steps
      • State your problem or question
      • Gather information
      • Formulate a hypothesis- (make a guess about your problem or question)
      • Design an experiment
      • Record and Analyze data- compare control and test groups
      • State your conclusion
  • 6. Scientific Method
    • Design an experiment:
      • You must include:
        • Control groups- the groups used for comparison (the standard)
        • Experimental groups- group that is being tested
  • 7. Scientific Method
    • Design an experiment:
      • Constants- things that are the same in both the control and experimental group (ex. same stopwatch used)
      • Variables: conditions that are being tested (only in experimental group) ONLY test 1 variable at a time!
      • Always repeat your experiment!
