3. 4. A hypothesis is an educated guess, a proposed answer to your problem. The manipulated (independent) variable, and the responding (dependent) variable.4. A hypothesis is an educated guess, a proposed answer to your problem. The manipulated (independent) variable, and the responding (dependent) variable.

4. Variables 5. Manipulated (independent) variable is a factor that is intentionally changed in an experiment by the investigator5. Manipulated (independent) variable is a factor that is intentionally changed in an experiment by the investigator 6. A responding (dependent) variable is a factor that is affected as a result of changing the manipulated (independent) variable6. A responding (dependent) variable is a factor that is affected as a result of changing the manipulated (independent) variable Constants are variables that are kept the sameConstants are variables that are kept the same Control is what you compare your results to… the normal results.Control is what you compare your results to… the normal results.

5. Research and Testing 7. Conduct research7. Conduct research 8. Plan and perform experiment8. Plan and perform experiment 9. There are two types of observations, qualitative (using your senses) and quantitative (involves measurements and numbers).9. There are two types of observations, qualitative (using your senses) and quantitative (involves measurements and numbers).

6. Data 10. Organize your data so that you may easily analyze the results. Your data can be used to make predictions and inferences. Use charts, graphs, and diagrams.10.

7. 11. One must state a conclusion after performing an experiment. You restate your purpose, describe your results and tell whether your hypothesis was supported or not by your data. Your hypothesis does not need to match.11. One must state a conclusion after performing an experiment.
