[irised] Animation of the Week

[John Lahr]

Jenda Johnson has started posting an "Animation of the Week" from the 
growing collection of video clips and animations that she has 
created.  See:  http://www.iris.edu/about/ENO/aotw/

This week's animations and clips describe the block-and-sandpaper 
model and show how it can be used to teach the concept of "elastic 
rebound."   In addition to geology and tectonics, earthquakes can 
provide a useful context for teaching or reviewing many basic physics 
concepts, such as sliding and static friction, forms of energy and 
conversion from one form to another, and the elastic properties of materials.

Cheers,
John
