"The Science of a Kiss" 9/11/08

Today we discussed our lab, "The Science of a Kiss: Measurement, Mass and Energy." It was a lab involving Hershey's kisses that taught us about the Law of Conservation of Energy. There were two jars of chocolate kisses at the front of the room, one was a tall glass and the other was sphere shaped. We had to guess which glass held more kisses, or if they held the same amount. My group thought the glasses held the same amount. It turns out that the spherical glass held about 40 more kisses that the tall glass. Mrs. Ezrailson explained that the spherical glass can hold more volume. I found this lab to be easy. We learned how to calculate Graviational Potential Energy and the final velocity. We also learned how to calculate kinetic energy; however I was confused on this part of the lab. We did not go over the answers to the kinetic engergy part of the lab, so I am not quite sure if did did this portion right. Overall, the lab was interesting and pretty easy.
