  1. Franchescuz+Steak J A Samantha Boland Jesus Chavez Brittney Hardy Abigail Murdock Daisy Plascencia Marisa Zubiate B M S D

  2. Introduction A • Analyze the UVA and UVB levels • Test the theory • Getting a tan, sunburn, or even skin cancer in a shorter amount of time the higher up you are. • Compare the intensity and levels of the UVA and UVB. 

  3. D What is UV-A and UV-B Radiation? UV-A Radiation: • Region of ultraviolet spectrum nearest to visible light • Causes tanning and contributes to aging of the skin UV-B Radiation: • Region of ultraviolet spectrum closer to higher frequency waves • Responsible for: • Sunburn • Aging • Skin cancer

  4. UV-A vs. UV-B B UV-A • Much lower intensity than UV-B, but its capability for damage is considerable. • Frequency: 320 to 400 nm • Lower frequency when compared to UV-B • Can pass through glass UV-B • Higher intensity than UV-A • Frequency: 280 to 320 nm • Higher frequency when compared to UV-A • UV-B can cause immediate damage to the skin, and it is directly responsible for major eye and skin problems.

  5. Hypothesis M • UV-A radiation level would be higher • UV-A is more commonly spoken of • maybe it’s more intense as altitude increases than UV-B is • UV-A and UV-B levels would rise as altitude increases • Less protection from the atmosphere • Graph will not rise straight up--as the balloon rises, the atmosphere will become thinner • Graph will raise at a steady pace • height raises because of the balloon rising to a positive slope

  6. A Equipment Used • Lab Pro • UV-A and UV-B sensors • Gondola • Notebook • Eraser • Stopwatch • Camera • Laptop • Pencil • Rope • Clip • String • Hose Winder

  7. D UV Intensity vs. Time

  8. B Results Interpretations • At 1000 ft. • Distracted as our mentor ran around with the nozzle reel trying to untangle the lines • Forced to extend time • Midway, attacked by another balloon • Caused a spike in our graph • Take-down • Problems with the markers • UV-A higher levels than UV-B • Rising/Falling values

  9. M Conclusion • Balloons tangling • Expansion of balloon pulling us! • Graph didn’t slant upward • UV-B was really low • No huge changes • UV-A levels went up/down a lot • Differences between UV-A and UV-B were HUGE!

  10. The End! Thank you, Mr. Fredriks, Dr. Keller, Mrs. Liddicoat, And everyone who helped us make this a success!
