1. Is there a difference between rocks and minerals? 2. Organize the following in a flow chart (with arrows) from broad to specific: • Elements • Rocks • Minerals Warm Up

Pass out HW!

Update Gradesheet! • If you are unhappy with your grade, please come talk to me for the possibility of a reassessment • • • Density and Atom Quiz (points possible=19) Birthstone HW (points possible=4) Mineral ID lab (points possible=18) Minerals in Everyday Life (points possible=30) Minerals Quiz (points possible=20)

Notes: Rocks • Rocks—a group of minerals bound together • Three types: ▫ Igneous �Formed by cooling of magma ▫ Sedimentary �Formed by compaction of sediment �Sediment—rock fragments, plant and animal remains, minerals that settle at the bottom of lakes and oceans ▫ Metamorphic �Formed by heat and pressure on other rocks

Notes: Rock Cycle

Closing • Match the type of rock with their method of formation: 1. Igneous 2. Sedimentary 3. Metamorphic a) Burial and Compaction b) Cooling of magma c) Heat and Pressure

Warm Up • Ms. Mc. Gowan chose to use pizza as her rock cycle analogy. Match the steps of the rock cycle with the steps of making pizza: 1. Sediment 2. Metamorphic Rock 3. Igneous Rock 4. Magma 5. Sedimentary Rock a. Collection of separate ingredients (dough, tomato sauce, cheese) b. Kneaded dough with cold tomato sauce and cheese c. Pizza just placed in oven d. Cheese on pizza in oven starts melting e. Cooled off pizza is ready to eat! Yum!

Partner Work: Rock Cycle • With your partner, think of an analogy for the rock cycle ▫ Example: Chocolate chip cookies • When you have thoroughly planned your analogy, draw the analogy’s cycle on your poster board ▫ ▫ Be creative! Don’t copy me! Be neat! Use color! You will be graded!

Closing • Explain your poster starting at sediment. Use the terms sediment, sedimentary rock, metamophic rock, magma, and igneous rock when explaining your cycle.

Warm Up • What is the difference between weathering and erosion?

Turn in HW!

Notes • Weathering—break down of rock • Erosion—movement of broken down rock • Magma—molten rock beneath Earth’s surface • Lava—molten rock above Earth’s surface

Sugar Cube Lab! • With the person next to you, follow the directions on the sugar cube lab worksheet • Keep your goggles on at all times! • Call me over when you are ready for me to heat your sugar cube! • This will be turned in for a grade!

Closing • Explain the rock cycle using a sugar cube.

Warm Up True/False: • Small grains of rock are formed when magma cools slowly.

Notes: Igneous Rocks • Intrusive (Coarse-grained) ▫ Trapped below Earth’s surface ▫ Takes long to cool therefore larger grains �Thousands of years • Extrusive (Fine-grained) ▫ On Earth’s surface ▫ Takes shorter to cool therefore smaller grains �Few hours

Notes: Sedimentary Rocks • Clastic ▫ Formed from fragments of other weathered rock • Chemical ▫ Formed from evaporation or chemical reactions • Organic ▫ Formed from remains of plants and animals

Notes: Metamorphic Rocks • Foliated ▫ Bands of different minerals in parallel layers • Non-foliated ▫ Uniform appearance, no banding

Video: Planet Earth Caves Write down 3 interesting facts about Planet Earth: Caves

Closing 1. O’Syris and friends found a rock and cut it open. They noticed it had small grains on the outside, but larger grains on the inside. Explain how this rock formed. 2. Why do igneous rocks have different textures?

Warm Up • Which rock is intrusive? Which is foliated? How do you know?

Rock ID Lab!

Warm Up • What is the only stage of the rock cycle that is in LIQUID form?

Warm Up • What type of rock was used to create many of the renowned monuments in D. C. ? • If I told you this rock was formed from heat and pressure, what kind of rock type is it? Is it foliated or non-foliated?

Warm Up • Name the stage of the rock cycle that represents the following states of a sugar cube: • • Sugar cube Powdered sugar Liquid Caramel Hardened caramel

Quiz • Put everything away except a pen or pencil • No talking, giggling, etc. • Raise your hand if you have a question • When you are done, hold on to your paper and put your head down

Closing • How was the quiz?

Warm Up • What does granite look like? • Based on your description, what kind of rock do you think it is (igneous, sedimentary, metamorphic)? And why?
