Yesterday in addition to letting my freshmen play with Geogebra to see if the ball landed in the can, I had my sophomores/juniors do the old Sine Spaghetti activity. Just for fun I walked around with my new Flip camera to document the festivities.
Here is one version of instructions for the activity (from Mrs H, I think?). (Not the version I used, but that one is trapped on a CD in my classroom right now.)
I don't know how instructive these will be, but it gave me a chance to use my new toy. I was careful to edit out faces - there are voice and backs of heads. Is that ok? Anyway, enjoy...
