  1. Introduction to science The Scientific Method Ms. Spera

  2. What is Science? • The knowledge obtained by, observing natural events and conditions in order to discover facts and formulate laws or principles that can be verified or tested.

  3. Testing your powers of observations

  4. Can you find the 5 hidden faces?

  5. How many horses are present?

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

  7. What is Scientific Method • Ask a question • Research the topic • Form a hypothesis • Test the hypothesis • Gather Data • Analyze Results • Draw Conclusions • Communicate Results

  8. State the Problem/Question • The problem identifies what you want to find out • Develop a clear statement defining the problem • State the problem in the form of a question

  9. Research • Make observations and research your topic of interest.

  10. Form a hypothesis • Predicta possible answer to the problem or question. • Example: If soil temperatures rise, then plant growth will increase.

  11. How to test an hypothesis • Develop a test to support your hypothesis • Must run multiple times • Must have only one independent and dependent variable • Must include two setups • Control Group • Experimental Group

  12. Variables • Independent Variable: The variable that is changed by the scientist; the ‘I control’ variable • Dependent Variable: The variable that might change because of what the scientist changes – what is being measured

  13. Practice Your hypothesis can TELL you what your variables are! Ex. If I drink Mountain Dew before bed, then I will not sleep very much. IV: Drinking Mountain Dew DV: the amount of sleep

  14. Experiment/ Test • Develop and follow a procedure. • Include a detailed materials list. • The outcome must be measurable (quantifiable).

  15. Collect/ Analyze Results • Modifythe procedure if needed. • Confirm the results by retesting. • Include tables and graphs

  16. Conclusion • Include a statement that accepts or rejects the hypothesis. • Make recommendations for further study and possible improvements to the procedure.

  17. Communicate the Results • Be prepared to present the project to an audience. • Expect questions from the audience.

  18. Think… Can name all seven steps? Collect and Analyze Results Formulate a Hypothesis Communicate the Results Observation/Research Problem/Question Experiment Conclusion
