    overheads and student answer sheet included where to get a wall map and dots to mark the earthquakes and informational images on earthquake magnitudes and occurrence to put next to your map Teachable Moments After a major earthquake a suite of materials are created that summarize information about the earthquake These can be used simply by posting the two or three page pdf on a bulletin board in the classroom or somewhere around the school or the powerpoints and animations can be used to make either a short or long presentation about the earthquake and regional tectonics The powerpoints are designed as a starting point with content at all levels to expand or contract to meet your needs and the level of your students Core Lessons with a Seismometer Additional Resources Vertical Seismometer Animation Horizontal Seismometer Animation IRIS How Does a Seismometer Work IRIS Como Trabaja un Sismógrafo Build your own Seismograph Students will gain a greater appreciation of how a seismograph works and a better understanding of recordings of ground motion that they see on seismograms In small groups of 3 4 students students are asked to design and construct a seismograph using common household and craft materials provided Students will demonstrate to the class how their seismographs record motion Download the activity pdf Exploring what you record Earthquake Tracking Instrument Sensitivity Locating Epicenters Scale Model Classroom Fault Model Triangulating Earthquake Locations Online Enter user defined data up to 4 station locations the user determined distance from the station to the epicenter and the location epicenter of a selected event and display this information on a map Access the Large View Map Generator or the Small View Map Generator to enter the station event information and generate your map How Do We Know Where an Earthquake Originated Do your students locate earthquakes by picking P and S arrivals from old textbook seismograms In this activity your students will use real 3 component seismic data from newsworthy earthquakes as part of the location exercise Includes instructions for locating events on inflatable globes or using an online mapping site Core Lessons without a Seismometer BOSS Lite Building Resonance Describe the impact of building resonance when assessing Earthquake Hazards Exploring Rates of Earthquake Occurence The activity allows the students to select their own region of interest and to interrogate the earthquake catalog to obtain quantitative data on the rate of occurrence of earthquakes of various magnitudes within their chosen region Redefining an Earthquake EQ Machine Lite Activity 1 In this activity students explore a mechanical model of a fault to develop a definition of an earthquake Developing arguments about earthquakes Earthquake Machine Lite Activity 2 In this activity students use a mechanical fault model to collect empirical data develop logical arguments about earthquake re occurrence and skeptical review other groups arguments Suggest an activity Have you found a good lesson or developed a new activity Please use this form below to share it with other teachers Describe your activity and we will

    The relative motion between the boom and mass is proportional to the ground shaking and causes a tiny electric current to be generated that is sent to the seismograph to be converted into a seismogram Unfortunately the spring will eventually pull the mass so the seismometer requires damping Oil or a magnetic damping system is used to dampen the AS 1 Seismometer What types of educational seismometers are available AS 1 Seismometer The AS 1 is a portable effective classroom tool for teaching about earthquakes and the instruments that record them The AS 1 has been loaned to many teachers through the Seismographs in Schools program The AS 1 electronics have recently been redesigned and production is currently underway TC 1 The TC1 is a vertical seismometer with a natural period of approximately 1s Open source hardware based on the arduino uno boosts the longer periods in its recordings so that teleseismic earthquakes are routinely detected in addition to regional seismic activity All plans for the TC1 and the interface between sensor and computer are freely available online to build your own but the TC1 can also be purchased as a kit Further information is available at http tc1seismometer wordpress com SEP In the UK the SEP seismometer system is a horizontal seismometer that uses electromagnetic induction to detect ground motion velocity and eddy current damping These seismometers are available from Mind Sets VS1 Rockwave has designed their VS1 seismometer to be the most advanced instrument available for home and educational seismology Install the VS1 in a corner of your garage or basement and you ll soon be exploring those tiny movements of the ground that are caused by earthquakes around the globe These seismometers are available from Rockwave EAI S102 The S102 is an inertial seismometer that measures ground motion with respect to an elastically suspended mass EQ 1 Vertical School Seismometer available commercially from Ward s Natural Science Guralp CMG PEPPV The CMG PEPPV records vertical ground motion It is a complex and sensitive instrument that can record global earthquakes Guralp seismometers are available from Guralp Systems How do I obtain a seismometer There are opportunities to include seismology in the classroom with or without a physical seismometer Check out our Instructional Resources page for more information Instruments can be purchsed from the suppliers listed above and IRIS resources are here to help get you started IRIS plans to donate instruments again in the 2013 2014 school year to schools in the US Apply to receive an AS 1 instrument and 2 5 day training from IRIS The application period will open in early 2013 for our workshop and instrument distribution The application will be available from this site AS 1 Assembly and installation guide AS 1 and AmaSeis manual AmaSeis software Below is a collection of instructional videos that step through the assembly of the AS 1 educational seismometer and highlight important features of the installation and operation of AmaSeis software Displaying your station in realtime Many
