6. Steps of
the
Scientific Method

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

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

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

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

12. Do you remember the next step?

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

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

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

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

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

18. Think you can name all seven steps?

Conclusion

19. Note: These variables will be defined in the next few slides.
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.

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

23. Independent Variable
The independent, or manipulated variable, is a factor that’s intentionally varied by the experimenter.
John is going to use 25g., 50g., 100g., 250g., 500g. of sugar in his experiment.

24. In this case, it would be the size of the loaf of bread.
Dependent Variable
The dependent, or responding variable, is the factor that may change as a result of changes made in the independent variable.
In this case, it would be the size of the loaf of bread.

25. 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.

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

27. Closure
A good question to use for a scientific investigation should be testable, and it should be connected to science concepts. Casey wants to do a scientific investigation about light. Which of the following questions would be best to use to guide his scientific investigation? a. Which type of light bulb burns the longest? b. Which type of light bulb is preferred by moms? c. Which type of light bulb is easiest to catch? d. What color of light is the prettiest?
