1. Aim: How do we describe minerals? Do Now: Think of a mineral you see or use everyday.

2. Why do people wear make-up? How can mica make the make-up shiny?

3. How do we define Minerals? Mineral: 1.Naturally occurring (formed in nature) 2.Solid 3.Inorganic (non-living, never alive) 4.Definite chemical composition 5.Crystal structure - Specific internal arrangement of atoms What is an atom? An atom is made of protons, neutrons and electrons. The atom is the smallest unit of any chemical element. They are the building blocks that make up each element and are too small to see with the naked eye. The tiniest piece of copper is made up of billions and billions of atoms stacked together.

4. How is one mineral different from another? Minerals can be made of one element, such as gold (Au), copper (Cu) or sulfur (S). Quartz SiO 2 Potassium Feldspar KALSi 3 O 8 Most minerals are made of two or more elements chemically combined to form a compound.

5. Identity the two most abundant elements in the earths crust that form most of Earth’s minerals. Evaporate or precipitate Cooling of lava or magma How do minerals form naturally? 90% of all minerals, in the earth’s crust, are made of oxygen and silicon (mineral family called silicates)

6. Why are minerals NOT rocks? Rocks are made up of one or more minerals.

7. Which mineral formed naturally? Diamonds are real, naturally occurring while cubic zirconium are man made in a lab. Summary Activity – Minerals Diamonds Cubic Zirconium

8. Identify the image that is a mineral? Glass Pearls Gold Glass is man made and pearls are organically formed by oysters. Gold is inorganically made from lava. Summary Activity – Minerals

9. Which one is a mineral? Why? Salt Rubbing Alcohol Salt or halite is a well known SOLID mineral. Summary Activity – Minerals

10. Explain what all these mineral have in common? Sulfur Halite Quartz Pyrite Calcite They all have crystal structure. Summary Activity – Minerals

11. Extra Summary - Questions 1.How can we define a mineral? 2.Describe what determines the physical and chemical properties to identify a mineral. 3.Why is cubic zirconium not a mineral? 4.How is a mineral different from a rock? 5.Why are minerals important?
