Storyboard Text

  • People believed that living things generated from nonliving things. I knew this couldn't be true so I proved them wrong. I conducted a controlled experiment which is a series of tests that are identical except for one factor, the manipulated variable. The factor that changes due to the manipulated variable is the responding variable.
  • COOL!
  • COOL!
  • I put two slips of meat into two jars, one covered and one not. The one that is not covered has lots of maggots in it. The one that is covered has no maggots. They did not spontaneously generate. Thus, disproving spontaneous generation.
  • I'm so glad you asked. Pasteurization is the process of cleansing food of bacteria by use of heat or liquid.
  • what's pasteurization?
  • I knew that Redi was on the right track so I continued his work with my own experiment. I put clear broth into flasks with curved necks. Then, I broke the necks off some of them letting bacteria in. Then, I left them sitting for one year. In the end, the flasks with no neck had lots of bacteria growth in it. The broth in the flasks with necks was still clear. I have created pasteurization from this experiment as well.
  • I case you didn't know, bacteria is a living organism.
  • Class, this is Louis Pasteur. He has disproved spontaneous generation along with Redi.
