Redi vs. Pasteur
Results of Redi's Experiment
Spontaneous Generation:
How both of the scientists' experiments relate to SG
Both of the scientists', Redi and Pasteur, experiments relate to Spontaneous Generation because both experiments deal with breaking the belief that animals come from non-living things.the only difference between the experiments is that one scientist, Pasteur, found out that life can only bring life.
Summary of Redi's experiment
Redi's experiment was based on people's long belief that maggots came from rotting meat. Although many people in the mid-1600s were stuck on the idea that maggots came from meat, Redi thought differently. Redi performed an experiment with three jars. One was open, the second was covered and, the last jar was covered with gauze so air could still get to the meat. Redi's hypothesis for this experiment was "
maggots only appeared in the flasks that were uncovered and where the flies could reach the meat to lay their eggs."
How did both of their experiments be successful?
The experiments that the scientists followed a method. The method is called the Scientific Method. This method contains seven steps. This is why these two scientists were successful in the end of the experiments.
Results of Pasteur's Experiment
The Scientific Method
1. Make Observations
2. Ask a Question
3. Form a Hypothesis
4. Test the Hypothesis
5. Analyze the Results
6. Draw Conclusions
7. Communicate with Others
Covered Jar
Uncovered Jar
Gauze Covered Jar
In the end of Redi's experiment, his hypothesis was correct. His hypothesis was that the jar that was uncoverd will have the maggots in the meat because of the flies.
Summary of Pasteur's Experiment
In 1864, Louis Pasteur created an experiment to test that "
...air was necessary for life...
"(Spontaneous Generation 1). Pasteur's experiment contained of a broth and a special flask that Pasteur himself created. The flask had a long neck that let air in and to kept microorganisms out to not contaminate his research.
Pasteur's Experiment
The results of Louis Pasteur was after the neck on the flask that he developed had broke a year and a half of the research. Due to this, the air created the microorganisms. This created the base of the origin of life and set solid ground for a new science called bacteriology.
