If you cover (in an nairtight container) the meat before it rots, it won't rot, since the bacteria that make the meat rot can't survive with out the air.

What processes do scientists use to answer questions about the world for example with the experiment with rotting meat?
Scientists use something called the scientific method. It goes like this:Scientific Method:1. Make an observation.2. Ask a question.3. Make a hypothesis.4. Conduct an experiment.5. Draw conclusions.6. Share your results.7. Do other experiments done by others agree?8. Yes or no?9. if no, do again.In the example of rotting meat that you mentioned, people used to think that flies just some how appeared where rotting meat was. The experimenter used two ways to show that there is no spontaneous generation but life comes from life. One: leave the jar with meat in it open to the air without a top. The second: meat in a jar but with a screened top. The jar with the open top became full of maggots (from eggs laid by flies) and the second jar had no flies. This proved that flies produce maggots which in turn change into flies.It wasn't until later that other scientists showed that 'unseen' life (bacteria) also were involved.
