Aim: What are minerals? - Cardinal Hayes High School
Aim: How do we describe minerals? Do Now: Think of a mineral you see or use everyday. Why do people wear make-up? How can mica make the make-up shiny? 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. How is one mineral different from another? Minerals can be made of one element, such as gold (Au), copper (Cu) or sulfur (S). Most minerals are made of two or more elements chemically combined to form a compound.
Quartz Potassium Feldspar SiO2 KALSi3O8 Identity the two most abundant elements in the earths
crust that form most of Earths minerals. 90% of all minerals, in the earths crust, are made of oxygen and silicon (mineral family called silicates) How do minerals form naturally? Evaporate or precipitate Cooling of lava or magma Why are minerals NOT rocks?
Rocks are made up of one or more minerals. Summary Activity Minerals Which mineral formed naturally? Diamonds Cubic Zirconium Diamonds are real, naturally occurring while cubic zirconium are man made in a lab.
Summary Activity Minerals 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 Which one is a mineral? Why? Salt Rubbing Alcohol Salt or halite is a well known SOLID mineral. Summary Activity Minerals
Explain what all these mineral have in common? Pyrite Quartz Halite Calcite They all have crystal structure.
Sulfur Extra Summary - Questions 1. How can we define a mineral? 2. Describe the structure silica and oxygen atoms make when bonded. 3. Describe what determines the physical and chemical properties to identify a mineral. 4. Why is cubic zirconium not a mineral? 5. How is a mineral different from a rock?
