ults to the public, he was criticized. Other scientists said that he made the air unfit for living growth, and that they needed the air to change from nonliving to living.Pasteur did the third experiment, in 1862. He took Spallanzani’s experiment, and the critic’s statements, and combined the two. He boiled pond water to kill all the living organisms. He poured that water into two curved neck flasks. He then proceeded to break the neck off of one of the flasks at the base. The flask with the broken neck started to become cloudy in a few days, however, the other flask continued to stay clear. He proved that the microbial organisms could not come from something nonliving. The curve in the neck of the flask allowed air to flow in, however, it caught all the microorganisms in the neck.Spontaneous generation is the idea that a living organism can come from something nonliving. This idea was entirely believed until the mid 1800’s. Three important experiments helped to disprove this idea. Due to the work of three men, we now have the knowledge that living things can only come from other living things in our environment....
