With the day starting pages 24- 26 were set out for the students to grab. Then Mr. Manning put the following daily question on the board and asked the class to figure out the two parts: A standing wave is produced in a tube 3 meters long. The tube has 2 open ends. This question requires the class to (A.) draw a standing wave in a 3 meter long tube with the first harmonic being sound. The second part to this question asks the class to (B.) find how long one wavelength in the tube would be. In order to find the length of one wavelength in the tube one must take 3 times (X) 2 resulting in an answer of 6 meters.

After reviewing the daily question Mr. Manning reminded his class about the test, which is on Thursday; don’t forget now! He also gave a reminder about the roller coaster presentation being on Friday. He stated that it must be at least 3 minutes long, keeping in mind that this is not a long presentation, so make it sound interesting enough to sell to the class. Next, the class was broken up into groups of two and began working on page 24. Here we had to use the following web site to access the information: [] Last but not least we took a gander at a video dealing with wind resistance. In Tacoma, Washington during the year 1940 engineers designed a bridge which they built wrong. With the wind being at the exact speed to force this bridge to sway back and forth in a twisting motion, eventually caused it to collapse. Thank god almighty no one died, except for a poor pup.  L
