Do i think the USA should change to the metric system. The answer is no. I think we should not change to the metric system because its to confusing and almost everyone in the U.S knows how to measure already. The metric system is confusing with all the numbers and formulas. The way we measure stuff today is already confusing as it is. Plus the way we measure things today sets us apart from the rest of the world. If we use the metric system what sets us apart from other countries besides freedom and all that good stuff. What im trying to say is I dont think the U.S. should turn to the metric system.
My goal for this class is to pass with a c at least. I don't like science but I am willing to learn about it. One of the things im looking forward to in the class is to cut something in half. My goals in high school are simple play football, get passing grades and just have some fun. It doesn't seem that hard but i know it will be. So to sum everything up i want to get a passing grade in Biology and cut something in half. These are my goals for Biology class.
