1. Scientific Method -A Review-

2. What is the Scientific Method? The Scientific Method involves a series of steps that are used to investigate a natural occurrence.

3. 6 Steps of the Scientific Method Problem/Question Formulate a Hypothesis Experiment Collect and Analyze Results Conclusion Communicate the Results

4. Steps of the Scientific Method 1. Problem/Question: Develop a question or problem that can be solved through experimentation. 2. Formulate a Hypothesis: Predict a possible answer to the problem or question. (If/ Then/ Because)

5. Steps of the Scientific Method 3. Experiment: Develop and follow a procedure. Include a list of materials. The outcome must be measurable (quantifiable). 4. Collect and Analyze Results: Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.

6. Steps of the Scientific Method 5. Conclusion: Restate hypothesis, were you right or wrong (results), validate w/ results, explain why 6. Communicate the Results: Be prepared to present the project to an audience. Expect questions from the audience.

7. Variables Independent (manipulated): What you will be changing. Dependent (responding): What will respond to change; one you measure. Constants (control): What must remain the same.

8. 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.

9. Types of Data Quantitative: measures are numerical (sales, participants, income etc.) Qualitative: measures are less tangible, such as users’ expressions of appreciation of your work, or critical acclaim of your artistic activity.

10. Terms You Should Know Scientific Law: A scientific law is based on experimental evidence It is general something which seems to always be true. Hypothesis: A hypothesis is a uncertain explanation of an observation or pattern which has been observed in nature. Scientific Theory: Valid explanation of some aspect of the natural world, based on knowledge that has been repeatedly confirmed through observation and experimentation System: a group of related parts that move or work together
