Learning Goal Students will be able to explain
Learning Goal: Students will be able to explain the rock cycle, explain the different components and characteristics of each rock type and classify rocks and minerals through observations. ie: grain, texture, color, hardness 4 In addition to 3, I can teach someone else about the rock cycle, the different components and characteristics of each rock type and how to classify rocks and mineral through observations. 3 I can explain the rock cycle, explain the different components and characteristics of each rock type and classify rocks and minerals through observations. ie: grain, texture, color, hardness. 2 I have a basic understanding of the rock cycle, the different components and characteristics of rock types and how to classify rocks and minerals through observations. ie: grain, texture, color, hardness. 1 I have a limited understanding of the rock cycle, the different components and characteristics of rock types and how to classify rocks and minerals through observations. ie: grain, texture, color, hardness. 0 I have no understanding of the rock cycle, the different components and characteristics of rock types and how to classify rocks and minerals through observations. ie: grain, texture, color, hardness.
Mineral Property – physical qualities which help to identify an object. Mineral – a mineral is a pure substance 4 properties that helps to identify it: Naturally occurring, inorganic (never alive) Is a solid - example: book, desk, pencil, etc. Definite chemical make-up/composition (H 20, Na. Cl (salt), Fe. O 2 (rust/iron oxide) Crystalline shape (a regular repeating structure)
Mineral Has definite physical properties – color, streak, fracture/cleavage, hardness, luster, density, conductivity, crystal form, transparency, etc. Luster – shininess of a mineral – how it reflects light Metallic & non-metallic Crystal shape – octahedron (8 sides), cube ( 6 sides, ) rhombehedron (6 sides)tetrahedron (4 sides) Transparent/transparency – ability to transmit light clearly so that an object can be seen distinctly through a substance. (glass, clear water) Translucent – semi-transparent – diffuses light (stained glass, block glass, skylights) Opaque – Not able to transmit light (book, desk, etc)
Crystal Shapes cube Octahedron Tetrahedron rhombohedron
Mineral Hardness – the ability of an object to scratch another object as directed on the Mohs Hardness Scale Streak – residue left on a ceramic plate after scraping mineral across its surface
Mineral Geologist – Scientist who studies rocks and minerals as well as the structure of the Earth. Rock – A naturally occurring solid substance composed of one or more minerals/substances.
