Using multiple visual representations to understand the earthquake cycle

The GeoCoder model displays block code (procedural representation, left), the Deformation Simulation (geometric representation, upper right), and the deformation over time graph (graphical representation, bottom right).

Symbols, objects, maps, graphs, and simulations are all powerful tools for conveying information. However, some complex ideas just can’t be captured in a single representation. In these cases, multiple visualizations can be used together to convey and connect several pieces of related information. For example, during the COVID-19 pandemic, news organizations used a combination of […]

New YouthQuake project engages urban middle school students in geoscience practices

The Seismic Explorer showing the number of earthquakes that occurred in California between 1980 and the present.

With most California residents living within a 30-minute drive of one of the state’s 500 active fault zones, the threat of earthquakes looms large. Scientists are constantly monitoring seismic activity, conducting risk assessments to determine when and where earthquakes may occur, and predicting the potential impacts to surrounding communities. Our new National Science Foundation-funded YouthQuake […]

Linking block coding, visual representations, and science concepts

The everyday work of modern seismologists—the scientists who study earthquakes, hazards, and risks—exists right at the intersection of two NGSS practices: “Analyzing and Interpreting Data” and “Using Mathematics and Computational Thinking.” Seismologists collect huge amounts of data from satellites, remote sensors, and GPS networks in order to monitor Earth’s surface for signs of land movement […]

GeoCode: Volcanic Hazards Module Released to the Public

GeoCoder model

We are excited to announce that our GeoCode: Volcanic Hazards module is available for public use! This free two-week curriculum for middle and high school students has been piloted by participating research teachers as part of the National Science-Foundation funded GeoCode project and extensively studied and redesigned based on our research. It is now available […]
