1. Do Now Copy the following two definitions: Qualitative Data: –Deals with descriptions. –Data can be observed but not measured. –Colors, textures, smells, tastes, appearance, beauty, etc. Quantitative Data: –Deals with numbers. –Data which can be measured. –Length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc. Physical ScienceFebruary 3 rd 2011 SWBAT identify the six steps of the Scientific Method

2. Qualitative VS. Quantitative Qualitative: Think ‘L’ for LANGUAGE Quantitative: Think ‘N’ for NUMBERS

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

5. We shall take a closer look at these steps and the terminology you will need to understand before you start a science project.

6. Problem/Question Observation/Research Formulate a Hypothesis Experiment Collect and Analyze Results Conclusion

7. Steps of the Scientific Method Problem/Question 1. Problem/Question: Develop a question or problem that can be solved through experimentation. Key Words/Phrases: “Wondered”, “Wanted to”,

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

9. Do you remember the next step?

10. 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.

11. Steps of the Scientific Method Experiment 4. Experiment: Develop and follow a procedure. Include a detailed materials list. The outcome must be measurable (quantifiable).

12. 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.

13. 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.

14. Think you can name all six steps? Problem/QuestionObservation/Research Formulate a Hypothesis Experiment Collect and Analyze Results Conclusion
