Rocks and Minerals
Vocabulary:
 MineralA naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition |  SedimentParticles of rock, sand and clay. |  ErosionThe destructive process in which water or wind loosens and carries away fragments of rock sediment. The process by which water, wind, or ice moves particles of rock or soil |
|---|---|---|
 Sedimentary RockA type of rock that forms when particles from other rocks or the remains of plants and animals are pressed and cemented together. |  DepositionThe process in which sediment is laid down in new locations - usually by settling out of the water or wind that is carrying it. |  Metamorphic RockA type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.. |
 WeatheringThe chemical and physical process that breaks down rock at the earth's surface.i.e. frost wedging, root wedging, lichen, acid rain etc. |  Igneous RockA type of rock that forms from the cooling of molten rock at or below the surface. |  Intrusive Igneous Rock(Intrusive rock) Igneous rock that forms when magma hardens beneath Earth's surface. |
 Extrusive Igneous Rock(Extrusive rock) Igneous rock that forms from lava on Earth's surface. |  Rock CycleA series of processes on the surface and inside earth that slowly changes rocks from one kind to another. i.e. when igneous rock is weathered and eroded and deposited somewhere else, then later compacted and cemented - it becomes sedimentary rock. |
Day 1: Mineral Properties
Today we began to look at the material that rocks of made of. Each Mineral has its own unique properties that help us classify each one. We used the characteristics of luster, hardness, color, streak and magnetism to classify minerals during a lab.
Here are the minerals from the lab and a brief discription.
Luster: Streak: Clear Hardness: It scratches Gypsum, but is scratched by Calcite Magnetic: no magnet or metal sticks to it.
Luster: Streak: Clear Hardness: Leaves a streak on the streak plate, but scratches both glass & Orthoclase. Magnetic: no magnet or metal sticks to it.
Luster: Streak: White Hardness: It scratches gypsum and fluorite scratches it. Magnetic: no magnet or metal sticks to it.
Luster: Streak: Clear Hardness: It scratches Gypsum, but is scratched by Calcite Magnetic: no magnet or metal sticks to it.
Day 2 : Rock and Minerals
Starter Questions:
1. Name two tests we use to identify minerals
2. Why do we need to study minerals to understand rocks?
There is so much interesting information that can explained about rocks and the different classifications.Because of this, these notes are to be taken from the presentation.
Day 3: Do you know your Rocks?
Starter questions
1. Name 3 characteristics of rock that can be used to classify them.
2. Why do we use so much detail to classify rocks?
Today we examined many rock samples and worked to classify, and describe as many as possible.
The headings that were used were Name of rock, Observations, What we know (process and where did it form), and Classification.
Day 5: Rock Cycle
Starter Questions
1. What must occur for a rock to become Metamorphosed?
2. Name three materials that can be cemented together to form sedimentary rock?
We examined the rock cycle today. This explains the way that each rock is transformed from one type to another.
Day 4: Rock Identification
Starter Questions:
Day 3 Quiz
Today we looked 15 different rock samples and used what we already knew about rocks to identify them. Below I have put images of the rocks and Key to help you identify the 15 rocks from the lab.
