Transcript of Redi's Experiment

Redi was trying to prove that Maggots came from flies, and that spontaneous generation was not real. He did not believe in spontaneous generation.
What was his hypothesis?
His hypothesis was that flies produced maggots.
How did he set up his controlled experiment?
He set up 3 jars, that all contained raw meat.
One jar had a plastic cover with a rubber band to hold it.
Another one had a cork to seal it shut.
Finally, the last jar had nothing to seal it.
All the jars had flies to surround the tops of the jars to see if maggots would appear.
What was Redi trying to prove?
What was his Independent variable?
The gauze that kept the flies away form the meat.
What was the Controlled variables?
The jars, type of meat, the location, the temperature, and the time.
What was his Dependent variable?
The dependent variable was whether the maggots would appear or not.
What was his conclusion?
He came to a conclusion that maggots form only when flies come in contact with meat. Spontaneous generation of maggots did not occur.
How many variables can be tested at a time?
Three variables can be tested at a time; Independent, Dependent, and Controlled variables.
Redi's Experiment

How does a scientific theory differ from a scientific hypothesis?
A theory is something that is concluded from experiments, while a hypothesis is yet to be proven. A hypothesis is only an idea you've created from your observations.
