Inquiry-based teaching modules (under development) that use the earthquake and volcano mapping software, Seismic/Eruption (also called SeisVolE; written by Alan Jones), to teach about earthquake and volcanic activity and related plate tectonics. The modules are designed for use in grades 7 – 12 (the grades that include most of the Earth science curriculum in US schools), although they can easily be adapted for use at the middle school level (grades 5 – 6) or at the introductory college level. |
|
Updated – New Modules in 2008 |
Teaching modules and resources for using the AS-1 seismograph and the AmaSeis software for earthquake and seismology education. Topics include installing and operating an AS-1 seismograph, using the AmaSeis software (including using the software without an AS-1 seismograph), calculating magnitudes, locating earthquakes using the S minus P method, analyzing and interpreting seismograms, etc. |

Seismic Waves and the Slinky:
A Guide for Teachers |
A teachers guide designed to introduce the concepts of waves and seismic waves that propagate within the Earth, and to provide ideas and suggestions for how to teach about seismic waves. Includes activities on elasticity, demonstrating seismic wave types with the Slinky, water waves in a wave tank, wave velocity, and the Human wave demonstration. |

Seismic Waves and the
Slinky: 4-page Lesson Plan/Handout |
A four-page version of the Seismic Waves and the Slinky teacher’s guide. Word (.doc) and pdf versions are also available. The Word of pdf versions can be printed in color or black and white and then copied onto both sides of 11x17 inch paper and folded to make a convenient and useful handout such as to accompany a slinky. |

Plotting Earthquake
Epicenters |
Create a plot of worldwide earthquake epicenters to display the narrow zones of seismic activity and aid in the understanding of plate tectonics. Epicenters are plotted on a small world map or a wall map. Earthquake data are obtained from the Internet. Extensions for plotting earthquake locations on the computer are described. |

Construct a 3-D model of the Earth to emphasize the (surprising) relative volumes of the main layers (spherical shells) of the Earth – crust, mantle, outer core and inner core. The activity includes a problem solving exercise for estimating volume (separating a sphere of clay into specific volumes corresponding to the relative volumes of the Earth’s crust, mantle, outer core and inner core). |
|
|
Develop an understanding of the structure of the Earth’s Interior by constructing a scale model of a “slice” of the interior of the Earth and study the material properties of the Earth’s interior. |
|
Journey to the Center of the
Earth Updated |
Take a virtual Journey to the Center of the Earth using a scale model of the depths to major features in the Earth’s interior. Learn about the Earth’s internal structure, composition, material properties and conditions. A two-page “Tour Guide” is also provided that can be used to make a small brochure that can be copied and given to each student. A template for making a construction paper “hardhat” for the tour is also included. A narrative is provided for the tour leader. Suggested connections to Jules Verne’s book, A Journey to the Center of the Earth, and the 1959 movie Journey to the Center of the Earth, are provided. |

Walk - Run Activity – An S and P Wave Travel Time
Simulation |
Use walking and running speeds and travel times to simulate the S minus P travel time earthquake location method. Travel time curves are determined by measuring speeds of walking and running. A hypothetical earthquake epicenter is calculated by triangulation. The method can be performed outdoors or in a classroom. |
|
Updated 11/11/04 |
EqLocate is an interactive earthquake location program that uses actual seismograms and user-selected P-wave arrival times to locate the earthquake. The program uses a method that is similar to the approach that is used by seismologists to routinely determine the location of earthquakes from around the world. The EqLocate program and sample data can be downloaded from Alan Jones’ web site. This tutorial describes how EqLocate works and provides detailed instructions on its use. Additional pre-assembled data sets are also available for download. |

Thermal Convection and
Viscosity of a Fluid |
Explore thermal convection with a simple hands-on activity using vegetable oil in a glass dish. Convection currents in the model are generated by heating the bottom of the dish using a sterno can or candles. The experiment models convection in the Earth’s mantle. Additionally, experiments with the viscosity of fluids develop understanding of the meaning of viscosity and the effect of temperature on viscosity. |

Plans for a simple seismometer that can be used to demonstrate the principles of the electromagnetic seismometer and how shaking of the ground is recorded by a seismograph. Experiments with a magnet and coil assembly illustrate the electromagnetic coupling used in most modern seismographs. Principles of data recording can also be demonstrated. The seismometer uses inexpensive and easy to assemble materials. There are several options for viewing the output from the seismometer. |
|
|
Plans are provided for building a simple seismograph for educational purposes. The seismograph uses homemade and readily available components. It can be attached to a computer for display and analysis. “Stomp test”, “make your own earthquake,” and weight drop experiments for teaching about earthquakes and wave propagation are described. |

Earth’s Interior – Travel
Times in a Constant Velocity Earth |
This activity provides instructions for comparing the travel times for a simple model of the Earth (a constant seismic velocity Earth) with actual P wave travel times. The travel times from the model can be calculated using a graphical method, using an equation and a calculator, or using a computer program. The results allow one to infer that the Earth’s interior structure must be heterogeneous. |

Using Earthquake Videos in
the Classroom |
Suggestions for effective use of earthquake videotapes in classroom teaching. An example of a handout to accompany an excellent earthquake video (NOVA series “Earthquake!”) is provided. |

Earthquake Shaking –
Building Contest and Shake Table Testing Updated |
Earthquake risk and the seismic design and construction of buildings is investigated using a building contest in which students build simple model buildings using basic design principles. After construction, the buildings are tested for their resistance to damage during earthquake vibrations using a simple, small, horizontal motion shake table. Comparison with building damage for actual buildings is provided through photographs and other information on the response of real buildings during strong earthquakes. |
