EVERYDAY SCIENCE

Detailed explanation-1: -There are many physical properties of minerals that are testable with varying degrees of ease, including color, crystal form (or shape), hardness, luster (or shine), density, and cleavage or fracture (how the mineral breaks).

Detailed explanation-2: -Color is not a property that can be used to identify a mineral. Explanation: Natural occuring, solid, inorganic, crystalline structure, and the same chemical composition throughout are the five properties of a mineral.

Detailed explanation-3: -Students will know that minerals are identified by using different properties such as color, luster, streak, cleavage, and hardness.

Detailed explanation-4: -Minerals can be identified by the shape of their crystals or crystallography. The shapes of crystals are determined by a number of factors such as the size and length of their surfaces (known as ‘faces’) and edges, as well as the angles between these.
