They were doing everything I hoped they would do all year!<br /><br />The most amazing thing to me is the kids had none of the post holiday drop-off that you normally expect. I may have to borrow my friend's high speed camera to film it. I'll let you know if that happens.bryan battagliahttps://www.blogger.com/profile/01195145851269463257noreply@blogger.comtag:blogger.com,1999:blog-951429983444008920.post-77950817859754482662011-01-03T23:27:51.995-05:002011-01-03T23:27:51.995-05:00This is really fantastic, and a great way to get k...This is really fantastic, and a great way to get kids away from massless ideal springs. <br /><br />One of the most intriguing demos I ever saw about a slinky was very similar to this, but the professor asked the question, what will happen when I let it go. He then prompted the audience that he could think of three possibilities: 1) the bottom of the slinky will start to fall the moment you release the top, and it will fall as a big uncoiled slinky. 2) the top will fall first, and the slinky will contract, with the bottom not falling until the top reaches it or 3) some other completely crazy explanation. <br /><br />I remember seeing this demo when I was a new teacher and honestly not knowing the correct answer. This is one of my absolute favorites. I also think it would easily lend itself to video analysis. Could you film the fall, and see that the coil you release in your hand is falling with an acceleration greater than g?Anonymousnoreply@blogger.com
