  1. Anatomy Scientific Method

  2. Scientific Method • A standardized means of organizing and evaluating information to reach valid conclusions. **it’s a process! • Terms you should remember: • Hypothesis • Experiment • Data • Theory • Law

  3. Terms expanded: • Hypothesis – an idea that explains your observations • A valid hypothesis has three characteristics • 1. Testable • 2. Unbiased • 3. Repeatable If a hypothesis satisfies these criteria and the scientific community agrees…it can be accepted as a Scientific Theory

  4. Observation & Define Problem Propose hypothesis Design Experiment Propose new hypothesis Collect & Analyze Data Redesign experiment Unbiased? No Yes Refine hypothesis Repeat experiment Not repeatable Correct Accept as a scientific theory

  5. General Steps for the Scientific Method • Observe • Define a problem • Hypothesis • Experiment • Collect and Analyze Data • Form a Conclusion • Scientific Theory……… • Scientific Law

  6. Two groups in an experiment…. Control and experimental Variables – Independent vs dependent (Independent – the one the experimenter aka you changes – graphed on the x axis Dependent – changes because of the independent and is graphed on the y axis

  7. Thumb war activity
