__**The Line Up:**__ Quiz Finish Wave Characteristics Activity Discussion Wave Speed

What a great day we had today, Thursday, March 16, 2009 in Mr. Manning's third period class! We started class right off the bat with a quiz. The quiz was on waves. We labeled parts of both a transverse and a longitudinal wave.

After the fabulous nine point quiz, we got in our groups that was assigned on Wednesday and finished our wave characteristics.

Once we wrapped up our experiment and calculations, we came back into the class to have a class discussion about the Mechanical Wave Characteristics Lab. Unfortunately, a bunch of the teams struck out on their calculations and had to redo the lab. We then discussed our calculations again and corrected our miscalculations. During our discussion, Mr. Manning showed us some of his own experiments. He showed us a few of his sweet toys that showed transverse waves.

This is during the lab, they are getting there results from prediction a

This was from Mr. Mannings demonstration during the discussion

The results after testing prediction A: 1st trail- 15 ft .82 s 18 ft/s 2nd trial- 20 ft .90 s 22 ft/s Length is a factor for wave speed! The results after testing prediction B: 1st trial- 10 ft 1.25s 8 ft/s 2nd trial- 10 feet 1.39 s 7.2 ft/s Amplitude is not a factor! 1st trial- 18 ft 1.06 s 16.9 ft/s 2nd trial- 18 ft 1.06 s 16.9 ft/s Frequency is not a factor!

We didn't finish all of the lab. It was postponed until tomorrow.

Week 1 roller coaster project due Friday and finish the rest of the lab **
