Summary:"This poster features a visualization of ground motion resulting from the February 21, 2008 M 6.0 earthquake that occurred near Wells, NV combines with the image of a faucet to illustrate the classic Earth science functional analogy; """"Seismic waves radiate outward from an earthquake's epicenter like ripples on water"""". For students, this discrepant image maps the unfamiliar concept of the spreading out of seismic wave (the target) to a similar but more familiar scenario of ripples on water radiating outwards in all directions after a droplet or pebble falls onto it (the analog). Not only is this visually discrepant, it also makes the material approachable by using ideas students are likely to have experienced. When presented at the beginning of seismic waves instruction, this visual analogy is the a catalyst for student-generated questions, inquiry, and learning."
