  1. The Scientific Method Not just for scientists! Adapted from http://panpipes.net/edit6200/

  2. What is it? • The scientific method is a logical sequence of steps that people use to identify, test, and answer a problem. • It is broken down into six steps: • State the problem. • Form a testable hypothesis. • Design an experiment. • Collect and analyze data. • Draw conclusions. • Communicate results.

  3. Taking a closer look… • Choosing a question or problem to solve: • Make sure it’s realistic and that you can gather the necessary resources. • When possible, choose a topic that really interests you. • Your question must include both a manipulated (independent) variable and responding (dependent) variable. • Safety first! • Make it new and interesting to YOU!

  4. Taking a closer look… • Creating a testable hypothesis: • “I predict that…” • Include a statement that shows cause and effect. (If, then, because.) • It must address the manipulated and responding variables. • Right or wrong does not matter!

  5. Taking a closer look… • Designing an experiment: • Carefully decide what your constants will be. • Decide what materials you will need. • Decide how you will measure your constants and your variables. • List all procedures in order.

  6. Taking a closer look… • Collect and analyze data: • Always keep constants and your manipulated variable in mind and follow your procedures. • Organize your raw data in a table.* • Use your data table to create a graph for your conclusion. (More to come!)

  7. Taking a closer look… • Drawing conclusions: • Restate your problem and hypothesis. • Summarize your procedures. • Explain how the MV affected the RV. (What does the graph show?) • Explain whether or not the results supported your hypothesis. • If not, why? • Future experiments.

  8. Communicate Results • Journals • Class reports • News reports • Magazines • Dr. reports • Others…..
