February 24, 2009 Mr. Manning was not in class. We came in and grabbed the Energy and roller Coaster worksheet. It was page 31,32,33,34. Our substitute teacher’s name was Mr. Marcelo. We came in to the class and he introduced himself. He told us what we were going to do. The worksheet had three different kinds of roller coaster. On the back there are three different charts. In the charts we are supposed to find the total energy, potential energy, kinetic energy, elevation, and velocity. Mr. Marcelo was walking around and offering help to everybody who needed it. He gave our group some pointers to help us fill in the charts much faster. He told us to fill in the given information first for all the graphs. Like that we won’t have to keep flipping the page back and forth. The first question was fairly easy. The question was about how a hot dog vendor in san Francisco rolled down the hill and up the once an earthquake strikes. They tell us the speed and the height it traveled. Yesterday we had an early dismissal and we did not get enough time to finish the worksheet that Mr. manning had left for us. We only had enough time to finish the first question and start the second question. The substitute teacher told us that this worksheet is to be done the next day. The second question was a little bit tougher because the question had more movements and also it had a loop. That’s what I did in class yesterday in the early dismissal that we had.
