Quake Coords Map Activity
A map analysis activity where students interpret seismic log data and a grid map to determine epicenter location. Modified for use without a compass, students use distance verification from potential points (L, M, N, P) to identify the unique epicenter at (8, 8). Features pre-drawn triangulation circles to accommodate classrooms without compasses.
Tremor Tracker Key
A comprehensive answer key and teacher guide for the Tectonic Tremors lesson. Synchronized with the updated Quake Coords activity (Epicenter at 8, 8) and Wave Watcher worksheet data. Features clear, renumbered answer sections and pedagogical tips for GED instructors.
Tectonic Tremors Slides
Interactive presentation slides covering plate tectonics, earthquake anatomy, P/S waves, seismogram interpretation, triangulation (finding the epicenter), the Richter scale, and volcanic hotspots. High-contrast visual design optimized for GED science instruction. Slide 2 now features a convergent interaction example and includes the transform boundary label. Corrected text contrast and vertical spacing across the deck.
Wave Watcher Worksheet
A practice worksheet focusing on interpreting seismograms to find S-P intervals, conceptual multiple-choice questions on triangulation and the Richter scale, and a short-response prompt regarding Earth's internal structure. Includes realistic seismic wave visualizations with precise scale markers.
Seismic Study Notes
Guided notes for students to follow along with the presentation. Includes sections for tectonic boundaries, earthquake anatomy, P/S waves, triangulation (finding the epicenter), the Richter scale, and volcanoes. Re-formatted to ensure a compact 2-page print layout and legible student work areas.
