Lesson Plan: Cohesive Properties of Minerals Geology

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the following cohesive properties of minerals: hardness, cleavage, fracture, malleability, and ductility.

Objectives

Students will be able to

  • define what mineral hardness is and describe the Mohs scale of hardness and its applications,
  • define what mineral cleavage is and mention the different types,
  • define what mineral fracture is and give examples,
  • compare between mineral fracture and mineral cleavage,
  • define mineral malleability and ductility and give examples,
  • recognize and define other physical properties including specific gravity, magnetic properties, thermal properties, taste, touch and smell.

Prerequisites

Students should already be familiar with

  • the chemical composition of common rock-forming minerals, such as quartz and calcite.

Exclusions

Students will not cover

  • parting,
  • tenacity,
  • reaction with acids,
  • solubility of minerals.
