### The steps of the scientific method

1. 1. The Steps of the Scientific Method If it looks like a duck, and sounds like a duck… Then it must be a duck! OR DOES IT?
2. 2. Making Observations <ul><li>Information is obtained using your senses </li></ul><ul><li>Observations can lead to questions </li></ul><ul><li>Questions can also arise simply by thinking about things </li></ul><ul><li>Research is involved </li></ul><ul><li>Questions lead to identifying problems </li></ul>
3. 3. Forming a Hypothesis <ul><li>This is a proposed answer to the question; a PREDICTION </li></ul><ul><li>The hypothesis must be testable </li></ul><ul><li>The hypothesis is written as an IF; THEN; BECAUSE statement </li></ul>
4. 4. Testing the Hypothesis <ul><li>Experiments are performed using variables </li></ul><ul><li>Manipulated variable – deliberately changed in order to create a change in another variable (often called the independent variable) </li></ul><ul><li>Responding variable – responds to the change caused by the manipulated variable (called the dependent variable) </li></ul><ul><li>Controlled experiment – when only 1 variable is changed at a time </li></ul>
5. 5. Drawing Conclusions <ul><li>Data collected during an experiment must be analyzed and interpreted </li></ul><ul><li>Information must be shared with others </li></ul><ul><li>Was the original hypothesis supported by the results? </li></ul><ul><li>If not, a new hypothesis must be formed and tested again </li></ul>
6. 6. Develop a Theory <ul><li>If the hypothesis was supported by the results of the experiment, then scientists can develop theories </li></ul><ul><li>Theories are never proven; they become stronger as facts continue to support them </li></ul><ul><li>If new facts disprove a theory, the entire process begins again and the old theory must be revised or replaced by a new theory </li></ul>
7. 7. Quick Review <ul><li>What is a Scientific Theory and how does it differ from a Hypothesis? </li></ul>
