  1. Steps of the Scientific Method

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

  3. We shall take a closer look at these steps and the terminology you will need to understand.

  4. Steps of the Scientific Method Develop a question or problem that can be solved through ______________ Step 1 2.Problem/Question: 3.experimentation

  5. 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.

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

  7. 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?”

  8. Steps of the Scientific Method Make observations and research your topic of interest. Step 2 4.Observation/Research

  9. Observation/Research John researches the areas of baking and fermentation and tries to come up with a way to test his question. He keeps all of his information on this topic in a journal.

  10. Steps of the Scientific Method Predict a possible _________to the problem or_______. Example: If soil temperatures rise, then plant growth will increase. Step 3 5.Formulate a Hypothesis 6.answer 7.question

  11. Formulate a Hypothesis After talking with his teacher and conducting further research, he comes up with a hypothesis. “If more sugar is added, then the bread will rise higher.”

  12. Steps of the Scientific Method Develop and follow a__________. Include a detailed __________list. The outcome must be measurable(quantifiable). STEP 4 #8,Experiment: 9. procedure 10.materials

  13. Experiment His teacher helps him come up with a procedureand list of needed materials. She discusses with John safety rules

  14. Steps of the Scientific Method Modify the procedure if needed. Confirm the results by retesting. Include___________,________, and_______________. Step 5 11.Collect and Analyze Results 12. tables 13.graphs 14.photographs

  15. 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.

  16. Collect and Analyze Results John examines his data and analyzes his results

  17. Size of Baked Bread (LxWxH) cm3 Size of Bread Loaf (cm3) Trials Control group

  18. Trials This simply means the number of times the experiment has been conducted under identical conditions.. John is going to test each sugar variable 3 times.

  19. Steps of the Scientific Method : Include a statement that ______ Or __________ the___________. Make recommendations for further study and possible improvements to the procedure. Step 615.Conclusion 16.accepts 17.rejects 18.hypothesis

  20. Conclusion John finds that 70g. of sugar produces the largest loaf. His hypothesis is accepted.

  21. Steps of the Scientific Method . : Be prepared to present the project to an audience. Expect questions from the audience. Step 7 Communicate the Results

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

  23. Think you can name seven steps?

  24. Scientific Method Problem/Question Observation/Research Formulate a Hypothesis Experiment Collect and Analyze Results Conclusion Communicate the Results

  25. Observe your world and come up with a question to answer using the Scientific Method!
