Scientific Methodintro Scientific Methodintro Presentation Transcript

  • The Scientific Method The scientific method is the way scientists get from asking a question to finding an answer.
  • Scientific Terminology data: information that you collect and record when you make observations or during an experiment scientific method: The process scientists use to find answers to questions or to find solutions to problems. The method uses organized steps to gather information and to test ideas. five senses: hear, see, smell, feel, and taste model: a representation of an actual object made to help you see things that cannot be observed easily experiment: the plan or test you design to find answers or to solve a problem hypothesis: a sensible guess or prediction of what you expect the answer to your question may be
  •  
  • Identify a problem & Research the problem Step 1
    • State Problem or Question: What do you want to learn?
    • What do you want to know in the world?
    • What do you observe?
    • Research: Find out as much as you can.
    • Research enough information about your problem or question.
  • Formulate a hypothesis Step 2
    • Hypothesis/Prediction: Try to predict the answer to the problem.
    • Another term for hypothesis is 'educated guess'. This is usually stated like
    • " If I...(do something) then...(this will occur)
    • Use observations and prior knowledge to form a guess
    • or prediction on how to solve your problem or answer the question.
    • What do you predict your solution or answer will be?
  • Conduct an experiment Step 3
    • Experiment/Procedure: The fun part! Design a test or procedure to confirm
    • or disprove your hypothesis.
    • Plan, design and carry out an experiment to test your hypothesis.
    • How will you test your hypothesis?
  • Record and Organize Data Step 4
    • Record and Organize Data: Record what happened during the experiment.
    • Record observations and data collected.
    • What are your results from the experiment?
    • How will you organize your data?
  • Reach a conclusion Step 5
    • Conclusion: Review the data and check to see if your hypothesis was correct.
    • Analyze data for a solution or answer.
    • Do they agree with your hypothesis?
    • What new facts have you discovered?
    • Summarize findings.
    • If an answer or solution is not found, repeat steps 2-5.
