Scientific Method Question/Purpose: –What is the problem? What do you hope to find out? –Example: What affect does music have on plant growth? Hypothesis: –What do you believe will happen? –Avoid “I think” or “I hope” –Includes Independent and Dependent Variables
Variables Independent: What is changing? *You can only have 1 independent variable* Dependent: What are you measuring? Controlled/Constant: What is staying the same?

Scientific Method Graph –Labeled and has a key. Use the mean when graphing results! Results –At least a paragraph summarizing the results –A graphic aid that illustrates those results Conclusion –At least a paragraph –Was your hypothesis correct? –What did you learn? –If you were to do this experiment again, what would you change?

KEEP IN MIND…. While this is a project done at home, we will offer some times during recess for students to work if they need assistance.
Thank you for joining us… If you are interested in purchasing a trifold tonight please see Mr. Joslin in the front of the library. Please feel free to see previous projects around the library Teachers will be available for questions
