Everything Students Need to Work Independently to Identify Rocks and Minerals
Step-by-step instructions lead students through the identification of 33 “unknown” mineral and rock samples; they examine physical properties including hardness, cleavage/fracture, tenacity, streak, texture, and grain size, then form their own identification key.
The set is housed in a compartmented collection box, and a comprehensive study guide is included.
