Reviewing Reading Guide

For the entire class period, Dr. E discussed the reading guide with the class. The last time that we had class we were only able to go over about half of the reading guide, and Dr. E wanted to make sure that all of our questions were answered before we had to take the quiz. The thing I enjoyed the most about discussing the reading guide was Dr. E's visual effects. To get everyone's attention, Dr. E first threw a plastic ball to show that when something is throw, it moves in a parabolic pathway, due to gravity. I thought that her example was very simple, yet spectacular. Dr. E was not only able to demonstrate what she meant by parabolic paths, but she also got her students involved and ready to pay attention by throwing the ball to them. The other thing I found helpful was when Dr. E was trying to explain what a simple machine was to the class. Dr. E grabbed a marker and a piece of paper and cut the paper down so it formed a square, she then took the square and formed a triangle out of the paper and then wrapped it around her marker; she was demonstrating to the class what an incline plane looked like. The last thing that grabbed my attention in Dr. E's class today was when she was throwing her pencil up and down. The reason that Dr. E was doing this exercise was to show that when you throw an object up, the time up and the time down will be equal (if caught at the same place). In dealing with that experiment, Dr. E also explained that velocity is zero at the top right when it is ready to come down; the pencil physically stops in mid air. It is not that the class did not already know that, but I think when Dr. E said that the pencil physically stopped in mid air, it caught the classes attention. I really enjoyed class today because I find it very interesting when Dr. E does hands on experiments in the classroom. I know that if Dr. E would not have done some of the things she did today in class, I probably would have not remembered them.
