Answer:

Francesco Redis experiment was conducted in 1668. His experiment was centered around the idea that maggots will arise from rotting meat. He conducted an experiment through his hypothesis that the maggots actually came from eggs laid by flies on the meat. To prove this he placed a piece of meat on 3 separate jars. He left one of the jars completely open, another sealed, and another covered by gauze. His hypothesis was proved to be correct when the only piece of meat that had maggots was the one that was left open.

Louis Pasteurs experiment was conducted in 1858. His experiment was influenced by a similar failed experiment conducted by Lazzaro Spallanzani in 1768. He was trying to prove that the air was not what was making the broth cloudy but what was actually making it cloudy was tiny microorganisms getting inside. To prove this, he created a swan neck flask that allowed air to come inside but trapped the microorganisms in a pocket on the flask.

Differences:

  • Redi used meat in his experiment while Pasteur used broth.
  • Redis experiment was to disprove Aristotles idea that some life forms arise from non living matter. while Pasteurs experiment was to disprove the idea that air gives life force.
  • Redis experiment was conducted in jars while Pasteurs was conducted in a hand made swan neck flask.
