Transcript of "Scientific method"

  1. 1. The Scientific Method involves a series of steps that are used to investigate a natural occurrence.
  2. 2. Observation Problem/Question Formulate a Hypothesis Experiment Collect and Analyze Results Conclusion Communicate the Results
  3. 3. Steps of the Scientific Method 1. ObservationObservation: Make observations and research your topic of interest.
  4. 4. Steps of the Scientific Method 2. Problem/QuestionProblem/Question: Develop a question or problem that can be solved through experimentation.
  5. 5. Steps of the Scientific Method 3. Formulate a HypothesisFormulate a Hypothesis: Predict a possible answer to the problem or question. Example: I THINK If soil temperatures rise, then plant growth will increase.
  6. 6. Steps of the Scientific Method 4. ExperimentExperiment: Develop and follow a procedure. Include a detailed materials list. The outcome must be measurable (quantifiable).
  7. 7. Steps of the Scientific Method 5. Collect and Analyze ResultsCollect and Analyze Results: Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.
  8. 8. Steps of the Scientific Method 6. ConclusionConclusion: Include a statement that accepts or rejects the hypothesis. Make recommendations for further study and possible improvements to the procedure.
  9. 9. Steps of the Scientific Method 7. Communicate the ResultsCommunicate the Results: Be prepared to present the project to an audience. Expect questions from the audience.
  10. 10. Do you know the differenceDo you know the difference between the independentbetween the independent and dependent variables?and dependent variables?
  11. 11. Independent Variable The INDEPENDENT, or MANipulated variable, is a factor that’s intentionally changed by the experimenter. John is going to use 25g., 50g., 100g., 250g., 500g. of sugar in his experiment.
  12. 12. Dependent Variable The DEPENDENT, or RESPONDING variable, is the factor that may change as a result of changes made in the independent variable. In this case, it would be the size of the loaf of bread.
  13. 13. Control Group In a scientific experiment, the control is the group that serves as the standard of comparison. The CONTROL GROUP may be a “NO TREATMENT" or an “experimenter selected” group.
  14. 14. Control Group The control group is exposed to the same conditions as the experimental group, except for the variable being tested. All experiments should have a control group.
  15. 15. Constants The constants in an experiment are all the factors that the experimenter attempts to keep the same.
