Uv Rays

Almost all the UV rays created by the Sun are prevented by the Ozone and atmosphere, but some UV rays come through and hit the Earth. It can be found by electronic devices, but it can also be found with something called UV beads. UV beads have a chemical that changes color when it is exposed to UV rays from the Sun. In this project, you will use UV beads, to explore how fast UV rays hit the earth.

Introduction

This project is to prove the pollution on this earth actually affects the ozone and how much UV rays hit earth. UV rays are rays that come from the sun and if a human receives to much can cause cancer. Pollution like gas and smoke can cause the ozone to deplete. This project with different color plastic wrap proves the hypothesis is correct. The darker the color wrap means the less pollution. The lighter the wrap is means heavier pollution. The all white wrap affect all the UV beads which were represented as people in about 1 minute and 45 seconds. This proves that if the sun can pass through our ozone easier that people can be affected drastically. The ozone layer is very small and society the way it is now will keep depleting this very small ozone layer. Today society tries to be more eco-friendly but it needs to change quickly before it is too late. This project shows also what can happen if society changed drastically to a more eco friendly solution like wind power, or solar energy.

The depletion of the ozone can cause global warming, cancer, mutations, sun burn, melanoma and more. “Laboratory and epidemiological studies demonstrate that UVB causes melanoma skin cancer and plays a major role in malignant melanoma development. In addition, UVB has been linked to cataracts -- a clouding of the eye’s lens.” (James, 2013) UV rays can be good for the body but small amounts too much can cause death and much more.” Ultraviolet (UV) light kills cells by
