Transcript of "Scientific Method"

  1. 1. Scientific Method A blueprint for experiment success.
  2. 2. What is the scientific method? <ul><li>It is a simple method scientists use to conduct an investigation. </li></ul><ul><li>It is a way to ask & answer scientific questions by asking questions & conducting experiments. </li></ul>
  3. 3. I. Question/Problem <ul><li>Ask a question about something observed. </li></ul><ul><ul><li>Why? </li></ul></ul><ul><ul><li>How? </li></ul></ul><ul><ul><li>What? </li></ul></ul><ul><li>Question to be solved. </li></ul><ul><li>Must be about something measurable. </li></ul>
  4. 4. II. Hypothesis <ul><li>Educated guess about how things work. </li></ul><ul><li>Prediction </li></ul><ul><li>Use If, then statements </li></ul><ul><ul><li>If ____ [ I do this ], then _____ [ this will happen ] </li></ul></ul><ul><li>Focus on one variable only. </li></ul>
  5. 5. III. Experiment <ul><li>Tests your hypothesis. </li></ul><ul><li>Is it accepted (right) or rejected (wrong) ? </li></ul><ul><li>Change only one variable at a time. </li></ul><ul><li>Use a control or control group ( A group that has nothing done to it. Standard used for comparison in an experiment .) </li></ul><ul><li>In order for results to be valid, conduct several tests. </li></ul>
  6. 6. III. Experiment <ul><li>Record your data in a data table. </li></ul><ul><ul><li>Numerical (quantitative) data organized in rows and columns </li></ul></ul><ul><ul><li>The specific independent variables are listed </li></ul></ul><ul><ul><li>• The number of trials are listed </li></ul></ul><ul><ul><li>Blanks are left for the data (dependent variable) to be filled in </li></ul></ul>
  7. 7. III. Experiment Title: Describing the Data Trial Variable 1 Variable 2 Variable 3 1 2 3 4 5 AVERAGE
  8. 8. IV. Data Analysis <ul><li>Reduce the data </li></ul><ul><ul><li>Average (Mean) </li></ul></ul><ul><li>Graph </li></ul><ul><ul><li>Graph the data to look for trends & relationships. </li></ul></ul>
  9. 9. V. Conclusion <ul><li>Summary of your experiment. </li></ul><ul><li>After your experiment, analyze your data to see if your hypothesis was accepted or rejected. </li></ul><ul><li>If hypothesis is rejected, g ive possible reasons for the difference between your hypothesis and the experimental results. </li></ul>
