Before I began my research on the topic, Ozone Layer, I thought it was going to be a difficult task to accomplish. While researching on Google.com, I saw numerous links that the site provided. As I briefly skimmed through several of the links, I didn't find one that interest me as much as I thought it would be. In doing so, I changed my research terms so that it could be more specific and narrower.

The sources I selected on Goggle was "How does the ozone layer protect us" (http://wiki.answers.com/Q/How_does_the_ozone_layer_protect_us). After reading the information that was provided by the site, the ozone layer acts like a sponge which absorbs the suns UV rays that it emits everyday. The first search terms I used were "Ozone layer." At first, these search terms gave me more results than what I expected it to give. I guess the search terms were too broad so I narrowed it down by changing the search terms to "How does the ozone layer protect us?" These search terms made it easier to understand the basic duty of the ozone layer which I stated earlier, that it protects us from the suns UV rays.

As I evaluated my terms, i know it had to be more narrow after the first attempt. In doing so, I decided to change my search terms from "ozone layer" to "how does the ozone layer protect us." After reviewing the results and information provide by these two terms, you can tell a difference between these two. When I compared them, the search terms "ozone layer" provided me with numerous information that is not necessary. While on the other hand, my second search terms which is "how does the ozone layer protect us" gave me a narrower result and basic information that is just enough to know how the ozone layer works.

In conclusion, I learned that the ozone layer not only absorbs more than ninety percent of the suns deadly UV rays but also protects us from the heat the the sun emits towards the Earth. I also learned that the ozone layer is made up of mostly Nitrogen. These research assignments have made me become a better student by making me more alert and organized. I now know how to use online research databases which will allow me to conduct my researches whenever I need to.
