9. What is the Scientific Method? The Scientific Method involves a series of steps that are used to investigate a natural occurrence.

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

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

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

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

14. 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.

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

16. 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.

17. 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.

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

19. What is a Hypothesis? The hypothesis is an educated guess about the relationship between the independent and dependent variables. Note: These variables will be defined in the next few slides.

20. Do you know the difference between the independent and dependent variables?

21. What is an Independent Variable? The independent, or manipulated variable, is a factor that’s intentionally varied by the experimenter.

22. What is a Dependent Variable? The dependent, or responding variable, is the factor that may change as a result of changes made in the independent variable.

23. What is a Control Group? In a scientific experiment, the control is the group that serves as the standard of comparison. The control group may be a “no treatment" or an “experimenter selected” group.

24. Control Group The control group is exposed to the same conditions as the experimental group, except for the variable being tested. All experiments should have a control group.

25. What are the Constants? The constants in an experiment are all the factors that the experimenter attempts to keep the same.

26. Let’s Practice!

27. Practice Experiment 1.Problem/Question What will help the plants grow better? Coke or Coke Zero?

28. Practice Experiment 2. Observation/Research: Plants grow best with water and light.

29. Practice Experiment 3. Formulate a hypothesis: (If_then statements are the best) If I give the plant Coke instead of Coke Zero then it will grow taller than if it has Coke Zero.

30. Practice Experiment 4. Experiment: Must include: ConstantsVariablesControl

31. Constants Constants- the things in an experiment that are kept the same:Constants- the things in an experiment that are kept the same: –Amount of soda –Sunlight –Temperature –Type of plant –Room you keep them in

32. Variables Variable- the things that change in an experiment or can be changed.Variable- the things that change in an experiment or can be changed. –In our question with Coke, Coke Zero and plants, what is the independent variable? The type of Coke.The type of Coke. –What is the dependent variable? The growth of the plant.The growth of the plant.

33. Control Control- the standard for comparison in an experiment.Control- the standard for comparison in an experiment. –The control in our experiment might be to set up additional plants that are given what? WATER!WATER!

34. Practice Experiment 5. Collect/Analyze Data CokeCoke Zero 3 cm1 cm 5 cm2 cm 10 cm5 cm 15 cm7 cm

35. Practice Experiment 6. Conclusion: The plant with Coke grew taller than the plant using Coke Zero. Our hypothesis was correct.

36. Summary 1.Write a 4-5 sentence summary over the essential question. 2.Glue your C-Notes on the right page 3.Complete the “Draw and Label a Picture” assignment on the left page. Begin working on the new unit vocabulary word maps: –Constant –Hypothesis –Inference –Observation –Variables –Control
