Using the Scientific Method to Solve Problems
[Scientific Process Notes] [Fall Semester] [Home]

  1. Identify Problem: Baby is crying.

  2. Identify all VARIABLES present:

    **Which variable is the cause?** Form a hypothesis for each variable. Then, isolate and test each variable keeping all other variables the same. This way the hypotheses that are wrong can be rejected.

  3. Hypothesis: The baby is crying because she is around too many people.

  4. Experiment: Take the baby out of the room.

  5. Result: Baby still crys.

  6. Conclusion: Baby was not affected by the people.

  7. Hypothesis: The baby is crying because she is hungry.

  8. Experiment: Return baby to original place and give a bottle to her.

  9. Result: The baby stopped crying.

  10. Conclusion: The baby was hungry. Did we finish yet?? Did we reject all other hypotheses?

    (The bady must be returned to the original condition because only one variable can be tested at a time. All other variables must remain the same in order to make the experimentation valid.)
