BIG IDEA: Rock changes through the rock cycle. (chapter 4, section 1) Vocabulary: rock cycle, erosion, weathering, deposition, sediment
through the rock cycle. How do the physical and chemical processes of weathering, erosion and deposition affect earth's geological features? What causes weathering, erosion, and depositon (include the factors that speed up and slow down each)? Monday (10/6/08): Brainpop: Rock Cycle with “quiz”
Take ch 4-1 quiz (come in 8:45am if absent) Go over ch 4-1: The Rock Cycle Processes that shape the Earth: 1. weathering (from water, wind, ice, and heat)—break down and wearing away of rocks into sediments 2. erosion (water, wind, ice, gravity)—sediments are moved 3. deposition—sediments are dropped and collect (builds up land) 4. heat (melting and cooling) a. a little leads to metamorphism b. a lot leads to melting (lava/magma) 5. pressure—buried sediment is squeezed by the weight of the overlying layers (compacting) 6. uplift—rocks are pushed up to the surface (where w/e/d begins) HOLT Transp E8-Rock Cycle (endless possibilities) and L65-Water Cycle Holt textbook pages 92-94, plus other transparencies Questions: 1. How long would it take to go through the rock cycle? (millions of years!) 2. Why are metamorphic rocks rarely formed near the earth’s surface? 3. Why is the rock cycle most active at continental plate boundaries? 4. Why are most of the earth’s rocks much younger than the earth as a whole? 5. How did the Homework: Study ch 3-4 for "quiz" (may not count) Chapter 3-4 CRCT practice questions--pages 84-85 and 116-7 --due Wed Study ch 4—Test Wednesday (entire chapter)

Turn in "Tybee Buddy" cards by Friday Tuesday (10/7/08): Take chapter 3-4 "quiz" (grade does not count if "B" or below) (worked on pages 84-85 and 116-117 CRCT review textbook questions)--finish by Wed
Review for tomorrow test (chapter 4)--as time permits: 1. review game 2. Rock Cycle with sugar lab/demo Homework: CRCT prep sheets due by Monday -----(will then go in CRCT review notebook) Study for tomorrow's test (ch 4)
Chapter 4 TEST (come in 8:15am if absent) Read rock cycle stories Brainpops x 2: Fossils, Dinosaurs Homework: Start reading chapter 6 (we'll revist chapter 5 near Earth Day) ---two column notes--due by Friday Ch 4 restest Friday 8:30am--optional BIG IDEA: Studying the rock and fossil record helps us understand Earth’s history and the history of life on Earth. Vocabulary: uniformitarianism, paleontology, relative dating, absolute dating, superposition, unconformity, radioactive/radiometric decay, half-life, fossil**, trace fossil, mold, cast, index fossil, eon, era, period, epoch, extinct Objectives: Describe how rocks and fossils show evidence of the changing surface and climate of Earth. Hook: IF the history of Earth were the length of 1 calendar year, on what date did modern humans arrive???? Thursday (10/9/08): Start going over chapter 6 (as well as section review questions) Go over ch 6-1: Earth’s Story and Those Who First Listened 1. Principle of Uniformitarianism=processes that we observe today (like erosion and deposition) do not change over time; the same geologic processes shaping Earth today have been at work throughout history 2. Catastrophism=geologic change occurs suddenly (meteorite/asteroid impacts) 3. BOTH are true (uniformitarianism occurs the most) 4. paleontology= study of fossils (past life) Go over ch 6-2: Relative Dating: Which Came First? 1. relative dating= younger or older (ex: age and/or height with classmates) 2. law of superposition= youngest rock at the top (if layers not disturbed) —example= “IN” box 3. Disturbed rock layers: page 158, figure 3 (can demo all 4 with colored sponges glued together) 4. Unconformities: a break in the geologic record created when rock layers are eroded or when sediment is not deposited for a long time (don’t worry about the types of unconformities)
Go over ch 6-3: Absolute Dating: A Measure of Time 1. absolute dates (ex: look at students age and/or height) 2. radioactive dating (look at unstable isotopes) 3. Half life (transp #P64)—and page 163, figure 2 4. Types of radiometric dating a. potassium-argon (for rocks older than 100,000 yrs old) b. uranium-lean (for rocks more than 10 million yrs old) c. rubidium-strontium (for rocks older than 10 million yrs old) d. carbon-14 (for dead organisms no older than 50,000 yrs old)

DYK: The oldest rock sample on record is a metamorphic gneiss from northern
Go over ch 6-4: Looking at Fossils 1. Types of fossils a. fossils in rock (mostly sedimentary) b. fossils in amber (soft, sticky tree sap) c. petrifaction (minerals replace organism’s tissues) d. fossils in asphalt (ex; La Brea “tar” pit in e. frozen fossils (ex: woolly mammoth found in f. trace fossils (ex: footprints, burrows, and coprolite) g. molds (the cavity) and cast (sediment fills the mold) (see page 168, figure 4) 2. Using fossils to interpret the past and date rocks a. MOST organisms do not become fossils b. Marine fossils found in mountains (environmental change) c. Index fossils from organisms that were only around during a short amount of time, so they can determine the approximate age of the rock layer they are found in (ex: ammonites/tropites were around 208-230 million years ago, and trilobites were around 400 million years ago)
Brainpop: Geologic Time
Go over ch 6-5: Time Marches On Holt Transp. #E111--Geologic Time Scale 1. Earth is about 4.6 BILLION years old, so scientists have divided Earth’s history 2. (draw 4 progressively smaller concentric circles, then label: eon, era, period and epoch) 3. refer to page 174, figure 3 for examples (don’t have to memorize)—which eon, era, period, and epoch are we currently in? 4. Paleozoic Era—began as all marine, then plants/animals moved also “moved” to land; ended with the largest mass extinction in Earth’s history 5. Mesozoic Era (age of reptiles)—ended with another mass extinction 6. Cenozoic Era (age of mammals) Optional: divide the class into 3 groups—each group will research one of the geologic eras (include climate, plant, and animal life) Homework: Work on ch 6 Scilinks--due Wed Critical Thinking (extinction of dinosaurs)---due Tue
