1. TEXTURE OF ROCK..
THE SIZE, SHAPE AND POSITIONS OF THE PIECES INSIDE A ROCK..
3 TYPES= FINE GRAINED, COARSE GRAINED AND MEDIUM GRAINED
ROCKS ARE MADE OF MINERALS, BUT MINERALS ARE NOT MADE OF ROCKS.

2. FINE GRAINED TEXTURE WE DON’T EASILY SEE WHAT IS INSIDE THE ROCK..
COOLS FAST, CRYSTALS DON’T LAST
EXAMPLE=TOMATO SOUP

3. MEDIUM GRAINED TEXTURE
WE SEE SOME OF THE PIECES INSIDE THE ROCK BUT NOT ALL OF THEM
MEDIUM=CRYSTALS SOME
EXAMPLE=OREO COOKIE

4. COARSE GRAINED TEXTURE
WE CAN EASILY SEE THE PIECES INSIDE THE ROCK
COOLS SLOW=CRYSTALS SURE CAN GROW
EXAMPLE=A SALAD OR “THE WORKS” PIZZA

5. A ROCK’S COMPOSITION
THE PERCENTAGE OF THE MINERALS THAT MAKE UP A ROCK..
EXAMPLE= GRANITE IS MADE UP OF..
10% MICA
55% FELDSPAR
35% QUARTZ

11. A MINERAL IS… NATURALLY FORMED-NOT MADE BY YOU OR ME
ROCKS ARE MADE OF MINERALS, MINERALS ARE NOT MADE OF ROCKS.

12. A MINERAL IS…
INORGANIC OR NON-LIVING

13. A MINERAL IS…
SOLID, NOT LIQUID OR GAS

14. A MINERAL HAS…
A REPEATING CRYSTALLINE STRUCTURE…THIS MEANS THE ARRANGEMENT OF ATOMS ON THE INSIDE GIVES THE MINERAL ITS SHAPE
ON THE OUTSIDE

15. Identifying Minerals
Each mineral has its own specific properties used to identify it.

16. Color The same mineral can come in a variety of colors
Ex. quartz
Impurities & other factors can change mineral appearance
Color is not the best way to identify minerals

17. Luster Describes how a surface reflects light
Ex. shiny/dull
Metallic- minerals containing metals are often shiny
Nonmetallic
Vitreous- glassy, brilliant
Silky-fibrous
Resinous-plastic
Waxy- greasy, oily
Pearly- creamy
Earthy- rough, dull

18. Streak Color of mineral in powder form
Observed by rubbing a mineral against a piece of unglazed porcelain called a streak plate
Streak doesn’t vary like color & is often different than a mineral’s color
More reliable than color

19. Cleavage and Fracture
Way a mineral breaks apart determined by arrangement of atoms
Cleavage- breaks along flat surfaces
Fracture- mineral breaks in an irregular way

20. Hardness Minerals resistance to being scratched
Ranks minerals from softest to hardest
Talc- softest known mineral
Diamond- hardest known mineral

21. Hardness

22. Density Mass in a given space/ mass per unit volume D= M/V
Density remains same regardless of sample size
Mass determined using balance
Volume determined using water displacement method
Comparisons can be made by hefting
Specific Gravity- ratio of an object’s density to the density of water

23. Special Properties
Fluorescence- minerals glow under ultraviolet light, ex. fluorite & calcite
Magnetism- ex. Magnetite
Radioactive- ex. contain radium or uranium
Effervescence- mineral fizzes (releases carbon dioxide) when in contact with hydrochloric acid=chemical reaction/double image.. Calcite
Halite=salty taste

24. Pictures of special properties…

25. ROCK VOCAB/FOOD COMPARISON LAB WORK
COMPARE THE ROCK TERM WITH THE FOOOD ITEMS ON EACH TRAY. PLEASE DO NOT MOVE THE FOOD ITEMS OFF THE TRAY.
EXPLAIN AND ADD A DRAWING OF HOW THE SPECIFIC FOOD ITEM ON THE TRAY MATCHES WITH THE TERM AND DEFINTION IT IS NEXT TO.
GROUP DISCUSSION IS A PLUS!!!!
