  30. Deductive reasoning example
    • This bread has peanut butter and jam.
    • This other bread has peanut butter and jam.
    • this other OTHER bread has peanut butter and jam.

  31. Inductive reasoning example
    • This bread has peanut butter on it.
    • = All bread has peanut butter on it.
  32. scientific PROCESS
    begins with an observation of things then a guess why that happens then testing to see if you were right. if not, you go to another hypothesis. and make the loop around till you find a hypothesis that is continually correct
