Hey all!
First, watch this video and bookmark it immediately!
I have implemented this into a few of my lesson plans; it is a short (1:45) video that shows how a pendulum's period directly depends on the length of the pendulum. All of the pendulums have the same fixed balance point, same starting amplitude, and same mass. As seen in the equation T=2pi(sqrt(l/g)), as long as gravity is kept at a constant rate, a variation in length is the only thing that would effect the period.
I highly recommend showing this video as a segue into any lesson involving waves!

Took me awhile to pick my jaw back up after watching!
ReplyDeleteI can definitely picture bringing this video up when pendulums come up in my course - building up the tension in the class and having us applaud and cheer as the pendulums all move towards recognizable patterns should be a lot of fun!
Brian,
ReplyDeleteIt definitely is a good way to get the class excited about the lesson! It reminds me of the screen savers on certain DVD players, where the player's logo will bounce around the screen, and you sit there in anticipation for when it hits the corner PERFECTLY!
In fact, I will mention that during my lesson!
Thanks for the comment,

This video was a beast in our READ 411 lesson!
ReplyDeleteGlen,
ReplyDeleteIt really was a crowd pleaser! I loved the "OHHHH!" "AHHHHH!!!" like it was fireworks!
