  1. How do we use the Scientific Method?

  2. State Problem • Your problem is what you are testing. • Choose something that you are able to research and that interests you.

  3. State Problem Cont. • Always have an Independent and Dependent variable. • Independent– What you are changing. • Dependent – What you are measuring. • Your problem must be written as a Question • Ex: If I give one plant compost, it will grow taller than the plants without compost.

  4. Gather Information • Perform any research necessary. • Often times, you will find previous attempts at what you are experimenting on.

  5. Form A Hypothesis • Write “If...then” statements when creating a hypothesis. • Ex: IF I water the plant every day, THEN it will grow tall. • Must address both variables.

  6. Hypothesis Cont. • What if I’m wrong? • It’s not about being wrong or right. • Educated Guess

  7. Perform An Experiment • This is how you test your hypothesis and where your data will be collected. • You should have at least ten trials. • Mistakes happen – DO IT AGAIN! 

  8. Analyze Data • 2 types of data • Quantitative – numbers • Qualitative – descriptions • You must write down daily what you observe and measure. • Data is your PROOF!

  9. Draw Conclusions • Conclusions tell you if your hypothesis was “SUPPORTED” or “NOT SUPPORTED” • Supported experiment is repeated to to collect more data. • NOT Supported hypothesis is revised and the process begins again.
