Dr. Christie's GPS and Geocaching Guide for Educators

Curricular Example: Categorizing and Graphing Lesson

Purpose and Goals

Teams of students will use GPS units to locate geocaches that their instructor has hidden around their school campus. Students will return to the classroom with the recovered geocaches, examine and discuss the contents of the geocaches, determine a number of possible ways to categorize the contents of each geocache, and then use Excel™ to create spreadsheets and graphs that represent the categorized data. The contents of each geocache can be sorted in two or more ways. Link to pictures of graduate students completing this lesson.
