Loci and Earthquake Activity (Geometry Activity)
Common Core Aligned Activity or Lab Project
This is a great activity to do after covering circles in Geometry. Loci can be a can be discussed more in-depth, but this project is just a quick overview to spark interest and to see how geometry is used in the real world. My recommendation is to make this a cross-curricular activity with Earth Science classes if possible.
This activity also includes guided questions and questions for discussion before and after the project.
This Activity Includes:
-Teacher Notes (PDF)
-Guided Notes and Activity (PDF and SMART Notebook)
-Answer Key (PDF)
Part 1 – Define locus and draw the locus of points that satisfy a given condition.
Part 2 – Draw the locus of points that satisfy two or more conditions.
Part 3 – Understand how loci relate to real-life constraints such as using seismograph readings to find the epicenter of an earthquake.
