  1. Urey-Miller Experiment The URL below has a diagram that displays the Urey-Miller experiment. This experiment's purpose was to simulate pre-biotic soup and the generation of early life. The experiment used water (H20), methane (CH4), ammonia (NH3), and hydrogen (H2). Looking at the diagram will explain this a lot better. Miller and Urey believed the experiment was successful. I have my doubts. Just producing 11 out of 20 amino acids is not close to a cell. Wikipedia will have much more information if you would like to know more about the original experiment. http://en.wikipedia....Urey_experiment Modernizing the Experiment I am wishing to perform a modernized Urey-Miller experiment for a local science fair. I need to perform research on what fossils and rocks can tell us about earth's early atmosphere. Some evidence points towards a much different atmosphere but I believe if I could get some input then this will turn out to be a much more thorough experiment. I would prefer direct evidence such as diagnosis of air bubbles in amber rather than speculation. Also I would like to see if any changes of the setup to the experiment could be made to reflect a more accurate representation. I would also love advice on how to put this together, sterilizing the equipment, tips, and how to analyze the chemicals. Any input would be great! Hope this interests many people, I will publish my results when I am done.
