This laboratory activity about Earthquake Depths is a great math-science crossover! It gives students practice with latitude & longitude and helps them process the fact that earthquakes don't just happen at Earth's surface but at varying depths. Specific skills practiced are plotting latitude & longitude coordinates on a map, plotting longitude vs depth on a graph, and visualizing the same data from multiple perspectives.

This is real earthquake data from actual earthquakes in South America. I condensed thousands of data points over the course of a year down to a manageable number for students to graph. Students will definitely be able to plot data points on a graph by the time they finish this lab (though they might hate graphs by that point!)

All graphs & pictures are created as shapes in MS Word, so they do not get grainy when printed.

Note: Parts of the lab refer to the ESRT. This is New York State's Earth Science Reference Tables. Even if you don't teach in New York State, they are a fantastic resource (both of information and to help students practice finding information elsewhere, which they will often do in the real world).
