1. The Method of Science

2. Science – process that uses observation and investigation to gain knowledge about events in nature.

3. Scientific method – an organized set of investigation procedures used by scientists.

5. Problem/Question: Develop a question or problem that can be solved through experimentation.
Observation/Research: Make observations and research your topic of interest.
Formulate a Hypothesis: Predict a possible answer to the problem or question.
Experiment: Develop and follow a procedure.Include a detailed materials list.
Collect and Analyze Results: Modify the procedure if needed.
Conclusion: Include a statement that accepts or rejects the hypothesis.
Communicate the Results: Be prepared to present the project to an audience.

6. Think you can name all seven steps?

7. Hypothesis – educated guess or testable prediction
Experiment – organized procedure for testing hypothesis
Control – standard for comparison
Constant – factors that do not vary in experiment
Independent variable – factor that is adjusted be the experimenter (x-axis)
Dependent variable – factor that depends on the independent variable (y-axis)

8. Accuracy & Precision Precision: Accuracy:
How finely tuned your measurements are or how close they can be to each other
Accuracy:
How close you are to the actual value

9. Accuracy & Precision may be demonstrated by shooting at a target.
Accuracy is represented by hitting the bulls eye (the accepted value)
Precision is represented by a tight grouping of shots (they are finely tuned)

10. Accuracy without Precision Accuracy & Precision
No Precision & No Accuracy
Precision without Accuracy

11. Scientific Law vs. Scientific Theory
Rule of nature that sums up related observations to describe a pattern in nature.
Ex. Law of Gravity
Explanation based on experiments – most logical explanation
Ex. Black Hole Theory
