Ultraviolet Detecting Beads Experiment
Lifelong exposure to ultraviolet radiation is a serious health hazard, and can result in different types of cancer and even death. I have performed an experiment to test this hypothesis: water intensifies the strength of ultraviolet rays. I will now tell you about the experiment and the results as well.
To conduct this experiment, you must:
1. Do this experiment at the sunniest part of the day: 12:00 A.M.
2. Take the ‘control’ bead and put it in a plastic bowl.
3. Take the ‘variable’ bead and put it too in a similar plastic bowl, and add ¼ cup of room temperature water.
4. Place both containers in a sunny area outside, such as a porch.
5. Set a timer for 15 minutes and leave the beads outside for that amount of time. 6. 6. Once the time is up, examine the beads and determine which one is darker in color.
My results for this experiment were very interesting. I saw that the bead in water was considerably darker in color than the dry bead.
Bead: Length of time in sun: Shade before exposure to sun: Shade after exposure to sun:
Control 15 minutes
Variable 15 minutes
In conclusion, I found that the bead in water was a darker shade than the dry bead. This leads me to believe that the same process would happen with your skin. Since water can reflect light, I think that it makes UV rays even stronger. It is harmful to one’s skin to go to a pool or beach without protection because the UV rays can be even more harmful. This information is useful to people who may not know that water can strengthen UV rays.
