  • The Scientific MethodIn Biology
    Mr. Slate
  • What is the Scientific Method?
    Ask a Question
    Do Research
    Construct a Hypothesis
    Test with an Experiment
    Collect Data, Analyze Results, Draw Conclusions
    Report your Results
  • Why is the Scientific Method Used?
    It is Systematic
    It organizes your thoughts and plans
    It is universal
  • Getting Started
    Find a topic that interests you
    ASK A QUESTION
    Where?
    When?
    Why?
    How?
  • Do Background Research
    Inform Yourself
    Be Aware of Current Findings
    Research Previous Experiments
  • Construct a Hypothesis
    Definition: A tentative assumption made in order to draw out and test its logical or empirical consequences
    Should Make Sense
    Should Be Falsifiable
    hypotheses. (2009). In Merriam-Webster Online Dictionary.Retrieved September 29, 2009, from http://www.merriam-webster.com/dictionary/hypotheses

    Experiment give appropriate answers?
    Experiment give strong supportive answers?
  • Test with an Experiment Continued…
    Make sure your Experiment…
    Has a Control Group
    Has an Experimental Group
    Limits Outside Factors
    Is Repeatable
  • Collect Data
    Do NOT be bias
    Be very systematic
    Do NOT “contaminate” the data
  • Analyze Results
    Use Statistical Procedures

    Fulfill the hypothesis completely
  • True or False
    Didyour experiment produce expected results?
    If not, why?
    Was the experiment bad?
    Was the hypothesis false?
  • Report Your Results
    Create a detailed procedure
    Make your research known
    This is how science/knowledge progresses
    Reflect on experiment
  • Reflection
    What have you learned?
    What further research should be done?
    This is the most important step
  • Review
    Ask a Question
    Do Research
    Construct a Hypothesis
    Test with an Experiment
    Collect Data, Analyze Results, Draw Conclusions
    Report your Results
  • Classroom Discussion
    Do we ever use the scientific method in everyday life without even thinking about it?
    What are some examples?
