Topic > UV Rays - 948

Almost all UV rays created by the Sun are blocked by ozone and the atmosphere, but some UV rays pass through and hit the Earth. It can be found through electronic devices, but it can also be found with something called UV beads. UV beads have a chemical that changes color when exposed to the sun's UV rays. In this project you will use UV beads to explore the speed at which UV rays hit the earth. Introduction This project serves to demonstrate that pollution on this earth actually affects ozone and the amount of UV rays hitting the earth. UV rays are rays that come from the sun and if a human gets too much of it it can cause cancer. Pollution such as gas and smoke can cause ozone depletion. This project with different colored plastic wrap proves that hypothesis to be correct. The darker the colored coating, the less pollution. The lighter the casing means more pollution. The all-white casing affects all UV spheres represented as people in approximately 1 minute and 45 seconds. This shows that if the sun can pass through our ozone more easily, people can be affected drastically. The ozone layer is very small and society as it is now will continue to deplete this very small ozone layer. Today's society tries to be more environmentally friendly, but it must change quickly before it is too late. This project also shows what could happen if society drastically changed towards a greener solution such as wind energy or solar energy. Ozone depletion can cause global warming, cancer, mutations, sunburn, melanoma and more. “Laboratory and epidemiological studies demonstrate that UVB causes melanoma skin cancer and plays an important role in the development of malignant melanoma. Additionally, UVB has been linked to cataracts, a clouding of the lens of the eye.” (James, 2013) UV rays can be good for the body, but small excessive amounts can cause death and much more.
