3. Through what method do scientists try to solve problems? Scientific method – Definition: a series of steps used to solve a problem.

4. The Scientific Method Identify the problem Gathering information Develop hypothesis Test the hypothesis Analyze the results Draw conclusions

5. The Scientific Method Identifying a problem Purpose? Enhance understanding Gathering Information Research Indicate if and where controversy exists Make a hypothesis Definition- an educated guess

6. The Scientific Method Working with a partner brainstorm several ideas for an experiment. Come up with a testable hypothesis.

7. The Scientific Method Test the hypothesis Experimentation – Procedures Choose variables Dependent variable—Change in response to other variables; what is being tested Independent variable—influences the dependent variable; variable that changes Control—independent variable is held constant; unchanged – Materials gathered Reproducibility and repeatability?

8. The Scientific Method Analyze the Results What occurred? – Observations – Measurements – Graphs – Charts Draw conclusions Answers the question Is the hypothesis correct – Theory—proven hypothesis Problems/Changes in the experiment

9. Using the article “Is Txting 2 Much Bad 4 U,” brainstorm with a partner about a possible experimental design. Be sure to come up with a possible Problem statement, hypothesis, and experimental design.
