Comment on this resource
In this animation, students view the movement of P and S waves created by an earthquake. The location of the earthquake is labeled on a cutaway image of Earth, and when students play the animation, they view each type of wave move. Accompanying text explains how scientists determined the structure of Earth's interior layers and how seismic waves travel through the interior. The text also prompts students ... Full description.

This demonstration uses an overhead projector, a bowl of water, and a beaker of sand to model a situation in which waves cannot pass through a central object. It is used to illustrate the fact that S-waves cannot travel through liquids. This is another piece of evidence for the nature of the Earth's interior from which we hypothesize that the Earth has a liquid outer core. Full description.

In this role-playing activity, students physically act out the motions of P-waves and S-waves in class to help them develop an understanding of how these waves work in the Earth. On this Starting Point page, users can access information about the exercise's learning goals, context for use, teaching notes and tips, teaching materials, assessment ideas, references and topics covered.

Recordings on this site present 164 aftershocks as they were heard at one seismic recording station. They occurred after an earthquake with a magnitude of 6.2 beneath and near New Zealand. All events are heard in rapid sequence, without the true time intervals between them. The main shock was at a depth of 30 kilometers, 10 kilometers below the interface between the subducting Pacific Plate and the ... Full description.

This activity has students use simple sine waves to explore constructive and destructive interference in seismic waves. After plotting the summative points of two sine waves, students connect the points to create the resulting complex wave. Once they have successfully drawn their complex wave, they will answer the questions listed on the student handout. Provided are: a list of materials, procedure, ... Full description.

This participatory demonstration of the influence of rigidity on the speed of seismic waves helps students understand the relationship between the speeds of seismic P and S waves and the rigidity (the resistance to shear deformation) and incompressibility (resistance to compression) of the medium. The demonstration requires only a watch or stopwatch. To create the waves, students stand side-to-side ... Full description.

In this activity, the process of finding the epicenter of an earthquake with a travel time graph is simulated. During the course of this activity students will model how earthquake waves travel through the Earth at different speeds, construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel time-curve), and use the constructed time-travel ...

In this exercise, students will study the three types of faults, investigate the association between faults and earthquakes, and examine the relationship between earthquakes and plate tectonics. There is a set of animations that illustrate the types of seismic waves, an exercise in which students determine the location of an earthquake epicenter using arrival times of P and S waves, and an exercise ...
