Science Dimensional Analysis

It's that time of year again...mid terms! Even though they seem so far away it's only a little bit over a month until the semiannual exams begin. In Science class we recently did a lesson that took two class periods to complete that contained material only to be found on our mid term. What we learned in class is called dimensional analysis and the 8th graders already learned a form of it in math earlier in the school year. Dimensional analysis is the process of converting something from one unit to the other. For example, you could find out how many meters are equivalent to five kilometers. There's also a more difficult version of this called double decker dimensional analysis which is twice the work. I'm explaining this all in a nutshell because if the insane name didn't give it away: this is very hard! I'm not confused though because we went over numerous, in depth examples during class and I copied everything down to the best of my ability. I actually found dimensional analysis very interesting and know that it will help me in the real world. Let's just hope I understand it enough to do well on my Science mid term! Good luck everyone!
