=Name:= Tim Murray =Title of Lesson:= Locating An Epicenter

Overview:
The **epicenter** is the point on the [|Earth]'s surface that is directly above the focus, the point where an [|earthquake] or underground explosion originates. Today's lesson incorporates your knowledge of earthquakes from previous lessons. Using various resources, we will today use our P/S wave information to locate the epicenter of an earthquake.

Standards:
Objective 2.04Analyze seismic waves including velocity and refraction to:
 * Infer Earth's internal structure.
 * Locate earthquake epicenters.
 * Measure earthquake magnitude.
 * Evaluate the level of seismic activity in North Carolina.

Classroom Logistics:
Classroom setup will be group and individual work at tables.

Tools + Rationale for each tool used:
laptops, ruler, compass, handouts with seismic station recordings

Prior Content Knowledge:
Earthquake general information: epicenter, focus, fault, P-S-L waves, time-travel graph

Prior Internet/Web 2.0 Resource Knowledge:
Connection to internet to specific sites (Wordle, Wallwisher, etc...)

Instructional Strategy/Activities (Lecture, workshop, etc.):
Internet site work, lecture, group discussion,

Student Deliverables:
Google docs-quiz, epicenter lab, wordwisher question
