The Scientific Method

  1. 1. THE SCIENTIFIC METHODNICOLE PISANO
  2. 2. WHAT IS THE SCIENTIFIC METHOD?The Scientific Method is a general pattern followed by scientists when conducting an experiment.
  3. 3. THE 5 STEPS OF THE SCIENTIFIC METHOD Observe Question Hypothesis Experiment Results/Conclusion
  4. 4. OBSERVE You observe a topic that can generate questions for further research.
  5. 5. QUESTION You ask a question about what is being observed. State the problem or question.
  6. 6. HYPOTHESISYou make an educated guess onwhat you think the outcome of theexperiment, or the answer to yourquestion will be.
  7. 7. EXPERIMENTYou will develop and follow aprocedure to test your hypothesis.The outcome must be measureable.
  8. 8. RESULTS/CONCLUSIONYou will record the results of yourexperiment, and repeat the experimentif need be. You will state if yourhypothesis was accepted or not andexplain your results.
  9. 9. WHAT ARE THE VARIABLES IN ANEXPERIMENT?Independent Variable- the variable that is changed in an experiment.Dependent Variable- What is observed during the experiment; changes as a result.Controlled Experiment- Changing one factor and observing its effect on another while keeping all other factors constant.
  10. 10. REVIEW 1Which step in the Scientific Method is given here?If I water and feed the plants, then they will grow to be tall and healthy. Observe Question Hypothesis Experiment Results/Conclusion
  11. 11. REVIEW 2Which step in the Scientific Method is given here?My hypothesis is accepted. When I watered and fed the plants daily, they grew. Observe Question Hypothesis Experiment Results/Conclusion
  12. 12. REVIEW 3Which step in the Scientific Method is given here?Today while walking home, I noticed that the plants in my front yard were starting to die. Observe Question Hypothesis Experiment Results/Conclusion
  13. 13. REVIEW 4Which step in the Scientific Method is given here?Why is it that some plants are growing, and other plants are dying? What affects the growth of plants? Observe Question Hypothesis Experiment Results/Conclusion
  14. 14. REVIEW 5Which step in the Scientific Method is given here?To answer my questions, I watered and fed the plants daily and recorded my findings. Observe Question Hypothesis Experiment Results/Conclusion
  15. 15. CORRECT!An educated guess, hypothesis, is made to determine the effect water and food will have on the growth of plants.
  16. 16. CORRECT!The results from the experiment were stated and a conclusion was made.
  17. 17. CORRECT!A simple observation was made about flowers.
  18. 18. CORRECT!Questions were formed about the flowers. These will be the questions carried out through the experiment.
  19. 19. CORRECT!An experiment was carried out to answer the questions to my problem.
