Tyler Deshong Physics TPJ 4/17/09 Period 4

Objectives: Collect Prelim. Designs Review Quiz Discuss Factors for the Speed of Sound Wave Speed Equation

Before students sat down, they picked up and sheet called, "Wave Speed Problems." Then, Mr. Manning started the class by handing back the quizzes that were done the previous day. I myself got a 6 out of 9. I made the mistake of mixing up longitudinal and transverse waves. Next Mr. Manning had students hand in their sketches and descriptions of their roller coasters. The students are in the middle of creating their very own roller coasters, and this is the first step. After the students hand in their sketches and descriptions, Mr. Manning began to go over the quiz. Listening to Mr. Manning helped me realize what I did wrong on the quiz. Next Mr. Manning had everyone get out page 6 and then began to call on people for examples of how the speed of sound would change. Then, Mr. Manning had his students get out their orange equation sheet and went over the Vsound equation for speed of sound as to the temperature. The class came up with Medium, Distance of Molecules, Temperature, Humidity, Altitude, possibly Reflection, and Pressure as the factors of the speed of sound. The next thing Mr. Manning planned to do was go over the equation for the speed of sound. Mr. Manning then gives a wave speed word problem for the class to do. After Mr. Manning went over the problem, he announced that the worksheet that the class got at the beginning of the class is homework. Being the great guy that he is, Mr. Manning gave the class time to work on it in class. The students had around ten minutes to work on the worksheet until the bell rang and all the students left. The picture below was of a demonstration of wave speed from Mr. Manning.
