FINAL TYBEE PAYMENT DUE

 

Extra Credit (optional):  Pick a specific rock (like granite, marble, etc)--must sign up first

--research (specific type, uses, composition, texture, where it's mined, other interesting info)

             (final product=a "Wanted Poster")--due October 7th

            MUST be in your own words and must use bulleted statements

 

 

  

BIG IDEA:  Rock changes through the rock cycle.

 (chapter 4, section 1)

 

 Vocabulary:  rock cycle, erosion, weathering,

                       deposition, sediment


Objectives:    Describe how each type of rock changes into another type as it moves

                                  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 Grand Canyon form? (it’s 1,600 meters deep over 2 billion years old)…Colorado River

                                  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)

                                                          

                   Homework:  e-mail parent letter

DYK:  The oldest rock sample on record is a metamorphic gneiss from

northern Canada, which is dated at 3.9 billion years old.

 

Brainpop:  Carbon Dating

 

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 Los Angeles)

e.      frozen fossils (ex: woolly mammoth found in Siberia)

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)

 

Look at fossil collection

 

 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)

 Advise from former students:

          **turn in everything on time or even early (usually not accepted late)
          **when answers are posted on-line, take the time to check them
          **read AND listen to the chapter TWICE--once at the beginning of the chapter, then a day or two before the test
          **earn as many homework passes as possible (don't waste your homework passes--can be used for extra points)
          **always be prepared for class (bring you materials every day)
          **be sure to write your name, date, period and assignment on all papers
          **DON'T PROCRASTINATE!!!!   --work ahead whenever possible
                     (try to finish the assignment the day it is assigned)
          **keep track of all handouts and worksheets (no credit if lost)
          **pay attention to Mrs. McMullan in class  (don't talk while she's talking)
          **study--tests/quizzes are harder than you are used to
                     (it's not just memorizing info)
          **begin studying for tests AT LEAST 2 days before the test
          **get organized
          **write down assignments in your planner/agenda/assignment sheet every day
                    (can verify later on teacherweb.com) --check off assignments when complete, then check off again when turned in
          **get assignments when absent from web page (classmates are unreliable)
          **look over what we learned in class when you get home every evening
                  (review notes every day)
          **save everything (we'll do a notebook cleanout together every so often)

         **don't talk while Mrs. McMullan is talking!!!!

          **expect this class to be challenging (it's advanced)
          **help do all the labs (if you let your group members do all the work, you will not
                         do well on the test)
          ** just "doing" your homework will not get you a 100% (it's graded)
          **check i-parent AT LEAST once a week (let your teacher know immediately
                      if there are mistakes)
          **try to compete in science olympiad, robotics, quizbowl, etc
                      (its fun and you get extra credit)
          **keep an "A" average so you can omit some stuff
          **do extra credit when offered (you may need it later)
          **you must make up all test and quizzes, as well as most labs
                     (usually come in 8:15am for tests and labs and 8:45am for quizzes)
          **be the first to answer the on-line bonus question, and you'll get a HW pass
          **ask questions if you are unclear about something AND participate in class discussions
          **write (print or type) so that Mrs. McMullan can read your work
          **pay attention to details and directions
          **don't give up; a couple of low grades doesn't mean you're "failing" the class
          **rewatch Brainpops at home
          **study in small chunks (5-10 minutes) for several days rather than an hour the day before the test
                     (you'll remember more)
          **try making flashcards or two-column study guides
          **if you get nervous during a test, try deep breathing and do the ones you know first
          **drink water before testing (don't overdo it)
          **have FUN
