Replicating The Miller-Urey Experiment in High School

Click For Summary
SUMMARY

The discussion focuses on replicating the Miller-Urey experiment for a high school science fair, emphasizing the use of gases found on other planets to assess their potential for supporting life. Key challenges include sourcing materials, constructing a safe tube system, and ensuring low-cost solutions. Participants highlight the necessity of obtaining liquefied gases from welding and medical supply stores, while stressing the importance of safety measures, such as gas gauges and regulators, to prevent mishandling.

PREREQUISITES
  • Understanding of the Miller-Urey experiment and its significance in abiogenesis.
  • Knowledge of gas handling and safety protocols, especially with liquefied gases.
  • Familiarity with basic laboratory equipment and setup.
  • Experience in constructing experimental apparatus, including gas lines and regulators.
NEXT STEPS
  • Research safe gas handling techniques for laboratory experiments.
  • Learn about the specific gases used in the Miller-Urey experiment and their sources.
  • Investigate the design and construction of gas delivery systems for experiments.
  • Explore low-cost alternatives for conducting chemical experiments in educational settings.
USEFUL FOR

High school students, science educators, and amateur scientists interested in experimental chemistry and the origins of life research.

For this year's science fair, I was thinking of replicating the Miller-Urey experiment, using a mixture of gases found on other planets, to determine which one has the most life potential.
The problem is getting started.
I would really appreciate some help on materials, methods, and building the tube system.
Low-cost is definitely important but I might have access to a lab.

Thanks in advance.

This is a simple version of the experiment. You will need to go to a welding supply store and to a medical supply place to get some of the gases. Liquified gas cannisters are potentially disastrous if mishandled - probably why this experiment is not going to happen in a HS classroom :) Get help with setting up the gas lines. You may have to rent some gas gauges and regulators.
