1. Scientific Processes The Scientific Process

2. What is Science? Comes from the Latin word scientia, which means “knowledge” A process that uses observation and investigation to gain knowledge about events in nature. Major categories include: Life, Earth and Physical

3. Science is based on: Theory: Explanation based on knowledge gained from observations and investigations. Law: Statement about what happens in nature that seems to be true all of the time.

4. The Scientific Method involves a series of steps that are used to investigate a natural occurrence. Scientific Method

5. 1. Problem/Question 2. Observation/Research 3. Formulate a Hypothesis 4. Experiment 5. Collect and Analyze Results 6. Conclusion

6. Steps of the Scientific Method Problem/Question 1. Problem/Question: Develop a question or problem that can be solved through experimentation.

7. Steps of the Scientific Method Observation/Research 2. Observation/Research: Make observations and research your topic of interest.

8. Do you remember the next step?

9. Steps of the Scientific Method Formulate a Hypothesis 3. Formulate a Hypothesis: Predict a possible answer to the problem or question. Example: If soil temperatures rise, then plant growth will increase.

10. Steps of the Scientific Method Experiment 4. Experiment: Develop and follow a procedure. Include a detailed materials list.

11. Steps of the Scientific Method Collect and Analyze Results 5. Collect and Analyze Results: Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.

12. Steps of the Scientific Method Conclusion 6. Conclusion: Include a statement that accepts or rejects the hypothesis. Make recommendations for further study and possible improvements to the procedure.

13. Think you can name all six steps?

14. Do you know the difference between the control and the variable?

15. Control:Control: –The part of the experiment that does not change. This is used to compare the results Variable:Variable: –The factor that can cause a change in the result of your experiment. –There are two types of variables: 1. Independent: What you change in the experiment. 2. Dependant: What changed due to your experiment?

16. Control vs. Variable Why is it Important to have controls and variables in an experiment?
