2. The Scientific Process involves basic steps that scientists follow in uncovering facts and solving scientific problems

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

4. Ask a Question Form a Hypothesis Design and Carry out an Experiment Record and Analyze Data Draw Conclusions Communicate Findings Further Inquiry

5. Steps of the Scientific Process Ask a Question 1. Ask a Question: Develop a question or problem that can be solved through experimentation. This is called a testable question.

6. Steps of the Scientific Process Form a Hypothesis 2. Form a Hypothesis: Predict a possible answer to the problem or question. This is called an educated guess. Example: If soil temperatures rise, then plant growth will increase.

7. Do you remember the next step?

8. Steps of the Scientific Process Experiment 3. Design and Carry out the Experiment: Develop and follow a sequential list of steps called a procedure. Include a detailed materials list. The outcome must be measurable.( think math related )

9. Steps of the Scientific Process Record and Analyze Data 4. Record and Analyze Data: Record what happened or changed during the experiment. Include tables, graphs, charts, and/or photographs.

10. Steps of the Scientific Process Draw Conclusions 5. Draw Conclusions: Include a statement that accepts or rejects the hypothesis. (My data does or doesn’t support my hypothesis) Restates results and may make recommendations for further study and possible improvements to the procedure.

11. Steps of the Scientific Process Communicate the Results 6. Communicate the Results: Share your findings with others: peers, parents, community

12. Steps of the Scientific Process Further Inquiry 7. Further Inquiry: Perform more experiments of a similar nature

13. Think you can name all seven steps? Ask a Question Formulate a Hypothesis Experiment Collect and Analyze Data Conclusion Communicate the Results Further Inquiry

14. Let’s put our knowledge of the Scientific Method to a realistic example that includes some of the terms you’ll be needing to use and understand.

15. Problem/Question John watches his grandmother bake bread. He ask his grandmother what makes the bread rise. She explains that yeast releases a gas as it feeds on sugar.

16. Problem/Question John wonders if the amount of sugar used in the recipe will affect the size of the bread loaf?

17. Caution! Be careful how you use effect and affect. Effect is usually a noun and affect, a verb. “ The effect of sugar amounts on the rising of bread.” “How does sugar affect the rising of bread?”

18. Formulate a Hypothesis “If more sugar is added, then the bread will rise higher.”

19. Experiment His teacher helps him come up with a procedure and list of needed materials.

20. Experiment John writes out his procedure for his experiment along with a materials list in his journal. He has both of these checked by his teacher where she checks for any safety concerns.

21. Collect and Analyze Results John comes up with a table he can use to record his data. John gets all his materials together and carries out his experiment.

22. Size of Baked Bread (LxWxH) cm 3 Amt. of Sugar (g.) 123Average Size (cm 3 ) 25768744761758 501296118812961260 10011881080 1116 250672576588612 500432504360432 Size of Bread Loaf (cm 3 ) Trials Control group

23. Collect and Analyze Results John examines his data and notices that his control worked the best in this experiment, but not significantly better than 100g. of sugar.

24. Conclusion John rejects his hypothesis, but decides to re-test using sugar amounts between 50g. and 100g.

25. Communicate the Results John tells his grandmother about his findings and prepares to present his project in Science class.

26. Further Inquiry John decides to test this same hypothesis in regards to the amount of sugar on the size of brownies.
