Redi
The purpose was so the flies won't get in the jar.
Francesco Redi disproved the theory of spontaneous generation in larger organisms during the 1600s with this experiment. By using flasks containing meat -- one open and one sealed -- Redi discovered that maggots only appeared on the uncovered meat that could be accessed by flies. The maggots were hatching from eggs laid on the meat, not from the meat itself. Pasteur continued the experimentation regarding spontaneous generation in the 1800s with the growth of bacteria on soup.
Scientists use the scientific method to answer questions about the world, which involves making observations, forming a hypothesis, conducting experiments, and analyzing results. In Francesco Redi's experiment with rotting meat, he tested the hypothesis that maggots arise from the meat itself or from eggs laid by flies. By using controlled conditions, such as placing meat in covered and uncovered jars, he demonstrated that maggots only appeared in the exposed jars, supporting the idea that they come from flies, not spontaneous generation. This method of systematic investigation allows for repeatable and verifiable results.

He was a scientist who experimented with maggots and meat and found out that maggots did not grow on meat
One prominent scientist known for experimenting with meat and flies is Francesco Redi. In the 17th century, Redi conducted experiments to challenge the prevailing belief in spontaneous generation by placing meat in jars, some covered and some uncovered. He observed that maggots only appeared on the uncovered meat, leading to the conclusion that flies were responsible for the emergence of life, not the meat itself. His work laid the groundwork for the field of microbiology and the study of biogenesis.
In the 1600's, the Italian scientist Francisco Redi performed experiments that showed that flies did not spontaneously generate from raw meat.
Francesco Redi
The purpose was so the flies won't get in the jar.
Flies are attracted to meat and will lay eggs on the meat, where they quickly hatch into maggots. But the flies are not indigenous to the meat.
Redi used a jar, meat and gauze. The gauze kept the flies off the meat. Redi's hypothesis was that if you kept flies away from the meat, maggots would not appear, because the flies did not lay eggs on the meat.
no it doesnt
Rotting meat doesn't create flies. Rotting meat attracts flies that lay their eggs on the meat. These eggs hatch and maggots emerge and proceed to feed off the rotten meat. After a period as a chrysalis, the maggots change and emerge as adult flies.
because they always appear where meat is rotting
Flies will often lay eggs on spoiled meat because they are attracted to the smell of the meat. The meat will provide a place for the eggs to incubate and also a source of food once the larvae hatch.
