Science is based on the feature of "<span>detailed research with reliable sources" among many other things. It is crucial that the tests can be repeated with the same results. </span>
The prediction Redi made was that Maggots weren't going to rise on the jars fully covered, he wasn't a scientist that actually suported the hypothesis that life was generated spontaneouly, that's why he made this experiment.
Although many scientists didn't agree with him, it was a very importante experiment for the new hypothesis to come because he was one of the first ones to present it to the world. The hypothesis accepted for some people at that time was that life could rise spontaneously because of rotten food. To prove them wrong, Redi took 8 jars containing meat inside of them, half of them were fully sealed, and the rest was let into the open air. You know what happened right? The ones that were sealed didn't grow up maggots, but the others did.
Things around us are usually made up of combinations of elements. These combinations are called molecules. Molecules make up combinations called compounds.
Water is an example. There are 2 oxygen atoms and 1 hydrogen atom (oxygen and hydrogen are elements). Together there molecules make up H2O (water) which is a compound.
I hope this makes sense! I'm happy to answer any other questions you might have :)
