Understanding Earthquakes: Comparing seismograms part of EarthScope ANGLE:Educational Materials:Activities
Jennifer Pickering
Introductory lesson that contextualizes how multiple instruments provide a more complete picture on an event.

Earthquake Intensity part of EarthScope ANGLE:Educational Materials:Activities
Jennifer Pickering
Introductory lesson that compares ShakeMaps between earthquakes in the same location but different magnitudes, and earthquakes of the same magnitude but different depths, to acquaint learners to the fundamental controls on intensity of shaking felt during an event: magnitude and distance from the earthquake source.

SeismicWaves Viewer & SeismicEruption Software part of EarthScope ANGLE:Educational Materials:Activities
Roger Groom, Mt Tabor Middle School
This activity includes both the Seismic Waves Viewer and the Seismic Eruption software to help learners better understand earthquakes, volcanoes, and the structure of the Earth. Seismic Waves is a browser-based tool to visualize the propagation of seismic waves from historic earthquakes through Earth's interior and around its surface. By carefully examining these seismic wave fronts and their propagation, the Seismic Waves tool illustrates how earthquakes can provide evidence that allows us to infer Earth's interior structure. Seismic Eruption shows seismicity (earthquakes) and volcanic activity in space and time from 1960 to present. When the program is running, the user sees lights, which represent earthquakes, flashing on the screen in speeded-up time. The user can control the speed of the action. In addition, the program can show seismicity under Earth's surface in three-dimensional and cross-sectional views. Earthquakes can be selected by magnitude and volcanic eruptions can be selected by volcanic explosivity index. In this way, large earthquakes and large eruptions can be selected to emphasize how different types of plate boundaries are characterized by different magnitudes of earthquakes (e.g. no major or great earthquakes occur on spreading ocean ridges). This lesson plan was developed by , Portland Oregon. Students investigate how seismic waves travel through Earth's internal layers and bounce and bend at internal boundaries between mantle, outer core, and inner core.

Pasta Quake: Exploring Earthquake Magnitude part of EarthScope ANGLE:Educational Materials:Activities
Paul Doherty (Exploratorium Teacher Institute) and Roger Groom (Mt Tabor Middle School) with improvements by ShakeAlert
This short activity provides an intuitive introduction to earthquake magnitude using an everyday item--spaghetti. Learners are introduced to the earthquake magnitude scale by breaking different amounts of uncooked noodles. Visual scale of the pasta emphasizes the relative differences between magnitudes with each whole step in magnitude. For older students, the demonstration helps students understand why seismologists use the nonlinear logarithmic scale to best graph the huge range of quantities.

Measure a Changing Volcano part of EarthScope ANGLE:Educational Materials:Resources
EarthScope Consortium
This hands-on demonstration illustrates how GPS can be used to measure the inflation and deflation of a volcano. Volcanoes may inflate when magma rises closer to the surface and deflate when the pressure dissipates or after an eruption.

Making Community Connections to Co-learn about Earthquakes part of EarthScope ANGLE:Educational Materials:Activities
Jennifer Pickering
Many people live in regions prone to earthquakes, tsunamis and volcanic eruptions, but the hazards and risks inherent in our communities may be very different. Making connections with learners from another location is a great way to share knowledge and practice science communication skills. Video conferencing applications like Zoom and Skype make it possible to connect with learners anywhere in the world. This activity provides a simple protocol, and a form for submitting a request to connect with a classroom teacher in Anchorage, Alaska.
