  1. Minerals

  2. Background before studying Minerals and Rocks • http://safeshare.tv/w/CGSaTEcQjF • http://www.youtube.com/watch?v=AYBw2Ye0gYY • http://www.youtube.com/watch?v=VmoZ4IG0lhQ

  3. Main Idea Supporting detail • Elements • A substance made entirely of 1 type of kind of atom

  4. Supporting details Main idea COMPOUNDS • Compounds are 2 or more different elements that have been chemically combined • Note : and 2 elements joined together form a structure called a molecule H2O H2O2 molecule of 2 Hydrogen atoms H = element molecule A molecule made of 2 hydrogen and 1 oxygen Atom – compound molecule

  5. 4 Qualities all minerals must have: 1. ## Naturally occurring – they are formed in nature they are NOT made by humans * Diamonds and other gems can be made in nature but they can also be created in labs but they are not minerals because humans have made them. Main Idea Supporting detail

  6. Supporting detail Main Idea 4 Qualities of minerals 2. ## Solid - most minerals are solids minerals have a fixed, ridged shape and volume (they take up space)

  7. 3. ## Have a definite crystal structure atoms line up in a regular, repeating pattern. Supporting detail Main Idea 4 qualities of Minerals: http://vasichkominerals.com/

  8. 4. ## A fixed chemical composition Always contains certain elements in the same proportion. They have a chemical formula. Au = gold H2O = water H2O2 = hydrogen peroxide C6H12O6 = sugar Most minerals are compounds, (2 or more different elements chemically joined). Supporting Idea Main Idea 4 qualities of minerals

  9. All minerals must: Solid Occur naturally in nature and are not man made Crystal structure Definite chemical composition which is usually a compound Qualities of Minerals: Review http://nature.ca/museum/press/2006/pr06-02-07_minstucson_e.cfm

  10. Create or re-draw you circle map – remember circle maps are used to define terms in Context or for brainstorming ideas in writing Write a definition for a MINERAL use a complete sentence MINERAL

  11. Main idea Supporting Details • Minerals are classified into groups based on composition • Silicates – form most of the Earth’s rocks • Oxides – form from metals and oxygen • Carbonates – form from the elements Carbon and oxygen • Native elements – copper, gold and sliver ***The grouping names are usually based on elements but occasionally compounds***
