My Favorites

In geology I liked studying about the differnt plate boundaries it was pretty cool. Even though it gave me a big challenge. While studying meteorology, I liked learning about the fronts, because now when I look at the weather channel, I can actually understand what the person is saying and not be totally dumbfounded. Oceanography, I didn't like to much it just was not that interesting to me. I dont know why. Astonomy was my favorite, I learned the most in this area, and it was the most amusing to learn about. I finally grasped everything, well all the basics about the universe. Although I agree and disagree with some things, I learned alot in this class. Thanks alot Mr. Dunn.
