What is the standard scientific method?
He, as do many of his science colleagues, states that the scientific method has four steps: 1) observation and description of a phenomenon or group of phenomena; 2) formulation of a hypothesis to explain the phenomena (in physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation); 3) …

How do scientist test their hypothesis?
Scientists (and other people) test hypotheses by conducting experiments. The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases.
What was the problem in Redi’s experiment?
Redi’s Problem: People believed that maggots grew out of raw meat.
What did Pasteur’s experiment prove?
Pasteur’s experiment showed that microbes cannot arise from nonliving materials under the conditions that existed on Earth during his lifetime. But his experiment did not prove that spontaneous generation never occurred. Eons ago, conditions on Earth and in the atmosphere above it were vastly different.
What was REDI’s conclusion?
Thus flies are necessary to produce flies: they do not arise spontaneously from rotting meat. Redi went on to demonstrate that dead maggots or flies would not generate new flies when placed on rotting meat in a sealed jar, whereas live maggots or flies would.
What is the conclusion of Redi’s experiment?
Redi recorded his data. He discovered that maggots appeared on the meat in the control jar, the jar left open. In Redi’s experiment, the results supported his hypothesis. He therefore concluded that the maggots were indeed produced by flies.
