Sampling Rocks
In this lesson, students will learn about sampling through an investigation of rocks found in the schoolyard. This will provide a start to understanding everyday statistics. They will first collect and analyze a sample of rocks from the schoolyard and array the collected rocks by characteristics such as size, weight, and color, to see if any generalizations can be made about the types of rocks that can be found in the schoolyard. Students will then be introduced to the notion of a sample and how the size and method of collection of a sample can bias findings.
