4-6

Today in physics we started off with a good old fashioned Daily Question. He wanted us to give an example of a resonating object that we have experienced in our own lives. Some examples included: guitars, drums, tuning forks, steel (as in train tracks), and a few others. Mr. Manning was thrilled at our willingness to participate in class. We then moved on to more information on beats and the Doppler effect. He went onto the website we were on yesterday and went into further detail about waves with similar frequencies. Mr. Manning continued to show us his love for tuning forks by hitting them some more. He hit two forks that were almost the same, and because they were different a neat little difference in the sound was produced that made many exclaim, "That's SICK." Even though the forks appeared to be in perfect healthy condition. Mr. Manning then went on to answer many questions. We watched an incredible video showing how fire trucks are nice examples of the working of the Doppler effect. We then watched a cool video with a jet breaking the sound barrier. We then had to work on page 26 for the remainder of class.
