SITUATIONAL GAME-


Date: 2015-10-07; view: 605.


Imagine that you are the crust (the mantle, the core). What's happening in your body?

 

2. THE EARTH

Use the charts below and the supplementary texts from SELF-STUDY BOOKLET- (SUPPLEMENTARY READING COMPREHENSION MATERIAL -PG.90)

(BRAINSTORMING – is an activity which aims to help students with this important pre-writing stage of getting ideas together. In this task, it is a pair-work activity.)

STAGE 1:

Group work responding to a text discussion. During this stage, each group will discuss its own topic.

 

 

GROUP A

 

 

 
 


GROUP B

 

 

STAGE 2: Sharing ideas of response to the text. Divide the students into new groups, so that each group has a member with different information.

Now the members of each new group will share their ideas.

STAGE 3: Now each student must jot down all the information he/she remembers.

 

I. Jig-saw plan (1-2 minute) short one-point talk

 

II. Multi-point conversation (5 minutes)

       
   
Lower mantle
  • 1793-652 miles
  • solid
  • composition similar to olivine
  • fairly even composition
  • density 470-358 lb/cubic ft
  • temperature 5040-32400 F
  • 68.3% Earth's mass
 
Oceanic crust
  • outermost 3-6 miles below oceans
  • solid
  • average composition similar to that of basalt
  • high silica and magnesium - SIMA
  • distinctive from mantle in its composition-more silica
   
 

 


       
   
Outer core
  • 3762-1793 miles
  • liquid
  • moving about
  • producing the Earth's magnetic field
  • iron-sulfur mixture
  • density 950-770 lb/cubic ft
  • temperature 57600 F
  • 29.3% Earth's mass
 
 
Continental crust
  • outermost 16-56 miles representing the continental masses
  • composition extremely complex
  • averaging granite
  • high in silica and aluminum - SIAL
  • density 195 lb/cubic ft
  • 2.5 denser water
  • temperature 1148-320 F
  • 0.7% Earth's mass
  • 0.7% 0f the Earth's mass
   
 


       
   
Inner core
  • Center
  • 3958-3762 miles
  • solid
  • iron-nickel alloy
  • density 1017 lb/cubic ft
  • temperature 81000 F
  • 1.7% Earth's mass
 
Upper mantle
  • 249 miles to 56 miles between continents
  • 3 miles beneath oceans
  • solid
  • composition as the mantle
  • rich in olivine
  • density 233 lb/cubic ft
  • temperature 2340-11480 F
