  1. Scientific Method 6 Steps to Follow

  2. Scientific Method • Scientific Method: A series of organized procedures used to solve problems • Is a problem solving technique. • All scientist use this method to answer questions. • What are the steps? • State the Problem • Research • Form a Hypothesis • Test/Experiment • Analyze Data • Draw a conclusion

  3. Purpose of Project • Explain why you are doing your project. • Example: I noticed that when we place bread in a drawer it doesn’t get moldy as fast as when it is left on the counter. With the cost of groceries rising, I thought that this experiment might show a way of keeping bread fresher longer and save my family a little money.

  4. 1.State the Problem • In question form. • Must be open-ended. In other words, it can not be answered with a yes or a no. • It must be testable. • Something you don’t know the answer to. • Must be specific.

  5. 2. Research • Used to educate yourself on your topic. • Do use many references from printed sources—books, journals, magazines, and newspapers—as well as electronic sources—computer software and online services. • Do gather information from professionals —instructors, librarians, and scientists, such as physicians and veterinarians.

  6. Bell Work 9/17/2009 • WooHoo it is almost Friday!!! • Question: • What do you now know about “Matter”, that you didn’t know before? • Get ready to turn in your matter research paragraphs.

  7. This is your prediction, based on the research you have done, that will answer your purpose statement. It is a prediction that can be tested Your hypothesis will be stated in an “If…., then….” statement. Example: “If fertilizer A is used on the plants, then the plants will grow larger” 3. Form a Hypothesis

  8. IV - Independent Variable What you physically change in the experiment. Example: the amount of light each piece of white bread receives. DV - Dependent Variable The outcome you are desiring to achieve. This variable is what is being measured. Example: the amount of mold grown over a period of time. Variables

  9. Constants - these are things that could change in the experiment but you will keep the same through each trial. Example: type of bread, same brand of bread, bought on the same day, used same type of light, same room temperature. Control - this is in the norm. you compare everything to this. Example: White bread that is left out based on how it is normally kept at your house. Variables Con’t

  10. Bell Work 9/18/2009 • Identify the IV & DV in the following statement: If you were measuring the growth rate of plants under full sunlight for 8 hours a day versus plants that only have 4 hours of full sunlight per day.

  11. 4.Performing the Experiment • List materials needed first. • Write the procedure. • They must be numbered. • In logical order and easy to follow. • Dohave only one independent variable during an experiment. • Do repeat the experiment more than once to verify your results. • Do have a control.

  12. 5. Analyze Data • Written description of all data. Facts only. • Examples: Data tables and graphs/charts

  13. 6. Conclusion: Your conclusion must answer your purpose question and support or reject your hypothesis 1st Paragraph – State whether your hypothesis was correct or incorrect. Explain why - support with research data 2nd Paragraph – State any experimental errors and explain what went right or wrong. What you would do differently to correct any problems, in this experiment 3rd Paragraph – Give your opinion of the lab. Was it helpful, why or why not?
