1. Get Started 1. Take out Notebooks/ 3-ring binder
Folders/notes checks – MANDATORY
2. Take out after school forms!
Monday, Tuesday, Thursday 3:15-5:30
3. Compare and Contrast the images of rocks.
What do you think specifically caused these differences?
^Happy Tuesday from the Tucan B A C

3. Agenda Afterschool forms Notebook Check Rocks Soil Minerals
Checks for Understanding
Summary/ Feedback/ Questions

4. ROCKS: Rocks are made up of two or more minerals.
They are not crystals
Some rocks form near the surface while others deep in the crust.
There are THREE major categories of Rocks:
IGNEOUS
SEDIMENTARY
METAMORPHIC

6. IGNEOUS ROCKS: Form when melted rocks harden
Fine-grained rocks (smooth) are from lava
Coarse-grained rocks (rough) are from magma.
Obsidian
Basalt
Pumice
Granite

7. Sedimentary Rocks:
Formed from layers of sediment, created by weathering, and erosion, that are dropped from moving water, and are squeezed and stuck together.
Fossils are usually found in sedimentary rocks.
Conglomerate rocks have large pieces and rom in shallow water
Siltstone is made up of smaller pieces
Limestone is made up of fine grained rock
Sandstone is made up of grains the size of sand.
Fossil
conglomerate rock
Limestone
Sandstone

8. Metamorphic Rocks
Existing rocks are changed through high heat and pressure to form different rocks
morph = change
Slate
Schist
Marble
Gneiss

9. ROCK CYCLE Like most cycles, the materials are used over and over.
Process include weathering, erosion, deposition, melting, compaction, and cementation.

10. The Rock Cycle

14. CFO’s Which type of rock is formed when other rocks change? Igneous
Metamorphic
Sedimentary
Which type of rock is formed when other rocks are compressed and squished?

15. CFO’s Which type of rock is formed when magma cools? Igneous
Metamorphic
Sedimentary
Which type of rock are fossils most commonly in?

17. Soil
What kind of soil do we likely have in Mississippi? (Silt)

18. “Dirt” versus “soil”

19. Minerals
Minerals are always solid with particles in repeating patterns- crystals
They are only found in Nature.
They are formed in the Earth’s mantle (from heat and pressure) – near the surface when oxygen, calcium and carbon combine in the ocean, and when hot, mineral-rich water moves slowly through the cracks in the Earth’s crust.

20. Examples of Minerals:
Iron
Calcite
Quartz
Hematite
Calcite
Diamond

21. PROPERTIES OF MINERALS:
Streak: color of the powder left behind when you rub a mineral against a white tile called a streak plate.
Luster: the way the surface of a mineral reflects light, either metallic (shiny) or nonmetallic (dull)
Hardness: a mineral’s ability to resist being scratched as measured by Mohs’s hardness scale

22. USES OF MINERALS: Diamonds make jewelry. Quartz makes glass.
Hematite can be used to make art.
Many things that we see and use every day are made from iron.

23. What are three testers that can be used to determine a mineral’s hardness?
fingernail, penny, nail

24. Minerals

26. Think/ Write About Why are these materials important to humans?
Where are they used?
Why do some have more value than others?

27. Last Items/ Questions HW:
Organize/Purchase science folder
Students may research natural gas drilling for extra background knowledge, if desired, for Friday
Extra Credit for students to collect, organize, and classify own rock collection due Monday 1/18
Think about your progress and effort in the first week. Is this how you want to start?
Soils lab tomorrow
