Miller Urey Experiment
In the 1920’s the idea was proposed that in early Earth’s atmosphere, which was made up of methane, ammonia, hydrogen, and water vapor, an electrical current passed through causing the formation of organic molecules. In 1953 Stanly Miller and Harold Urey designed and preformed an experiment proving this hypothesis.
Experiment Process- Boiling chamber was heated to vaporize “ocean” water. The water vapor then traveled through a tube to the “atmosphere”. An electrical current which represented lightning passed through the “atmosphere”, causing the formation of organic material such as amino acids.
