This document provides an overview of a Mining Matters Teachers Workshop that will take place on April 27, 2015 at Dynamic Earth in Sudbury, Ontario. The workshop will include activities that teach teachers about the relationship between minerals, rocks, and everyday products; the types of mines in Ontario and their importance to the province's economy; and a design challenge activity where teachers learn to classify and identify rocks. Teachers will have the opportunity to examine rock and mineral samples using testing equipment and match the samples to specific minerals and products.
