Curated OER
Topo Triangulation
Students investigate how to read a topographical map and triangulate with just a map. They convert a compass measurement to a protractor measurement, reverse a bearing direction, and using a worksheet take a bearing of certain landmarks...
Curated OER
Topos, Compasses, and Triangles, Oh My!
Young scholars triangulate using a compass, topographical (topo) map and a view of outside landmarks. They take a field trip to another location away from school and mark discernible landmarks (like mountains or radio towers) and changes...

Finding the Epicenter
The epicenter is the point on the ground above the initial point of rupture. The 10th instructional activity in a series of 20 encourages scholars to learn to triangulate the epicenter of an earthquake based on the arrival times of...

Space Science:Wherever You Go, There You Are
Learners explore navigation principles by observing, measuring, and interpreting data to determine locations. Using a compass, compass rose, and a transit, they plot courses and discover the workings of the Global Positioning System...

Earth Science: In Depth Look at Earthquakes
Pupils engage in an interactive Internet lesson covering the reasons and results of earthquakes. After reading eyewitness accounts and viewing animations, they use seismograms to measure and locate the epicenters. In an ongoing study,...
Curated OER
How do we measure global earthquakes?
Students examine three seismograms of a recent South American earthquake recorded by USGS stations. They measure the S-P distance and use a P and S wave travel-time graph to find the epicenter distance for each seismogram. In addition,...

Teach Engineering: Topo Triangulation
In this activity, students will learn how to read a topographical map and how to triangulate with just a map. True triangulation requires both a map and compass, but to simplify the activity and make it possible indoors, the compass...
