Honors Thesis


The existence of extraterrestrial life has always been a fascinating topic for human beings, and the discovery of water on Mars reignited the debate over whether life on the planet is possible. This project describes the methods of proving life from a soil sample. Biuret and Benedict reagents are used for protein and carbohydrate tests, which are the essentials of life. The presence of protein and carbohydrate is indicated by the purple or deep blue and light green color change of the reagents; however, after testing the soil with reagents, it was discovered that the color change might be challenging to distinguish in the muddy solution. Therefore, it was decided that the soil solution should be decanted for 5- 10 minutes to see a noticeable color change.
