Activity 4

This activity was all about putting materials into pop bottles and half of the pop bottles had paint on the top of them, then putting thermometers just above the materials not touching them, and having a lamp right above them. The point of this was to see which materials reflected most heat. The white sand with the clouds on it didn't even heat up really. I learned that when sunlight is cut off by clouds it blocks out the sun rays causing the weather to be cooler.El Niño is characterized by unusually warm ocean temperatures.http://en.wikipedia.org/wiki/El_Ni%C3%B1o. This relates to the water bottles because when the water bottle had clouds the water didn't warm up much if any. The bottle without clouds definately warmed up alot faster and more than with clouds.
