5-1



When we first got into class we picked up a packet called "Standings Waves, Harmonics, and Resonance Notes." This packet's pages are 20-23. Mr. Manning started class by collecting week 3's work on our Roller Coaster Project which was the Technical Manual. Everyone has until the end of the day at no later than 3:15 to turn it into Mr. Manning. If you don't get to him in his class before he leaves, it will be considered late. Mr. Manning then told us the official day of our Unit 10 test which will be on Thursday May 7th. The study guides, of course, will be due the same day of the test. After this reminder we listened, and took some notes on the packet that we got at the beginning of the period. The notes focused on standing waves, how they are effected by fixed ends and free ends, along with what happens when two standing waves pass through each other. For these notes there was also a demonstration in the back of the classroom, which was a slinky that had one fixed end and one free end. The free end of the slinky could moved along the string back and forth and had displayed multiple harmonics and waves. The picture at the top of the page shows the slinky attached to the string. For the remainder of the period we worked on yesterday's lab that Mr. Manning passed back to us because the grades weren't very good, and also worked on our homework which was page 23 from the Standing Waves, Harmonics, and Resonance Notes Packet.
