Double Buble Maps

    DOUBLE BUBLE MAPS  Fe AND Al

When we compare or contrast items, we make statements of similarity or difference. These statements, as with statements of classification, may be based on the way things function, the way they look, their use, where they are found, etc. It is important to remember that when you compare and contrast, you make parallel statements; that is, you make similar statements about the items under discussion. You compare colours with colours, size with size, the policies of one government leader with the policies of another. You don't compare sizes with colours, or locations with use, or policies with personal beliefs.

 The eight map types are:

1. Circle Map

used for defining in context

2. Bubble Map

used for describing with adjectives

3. Flow Map

used for sequencing and ordering events

4. Brace Map

used for identifying part/whole relationships

5. Tree Map

used for classifying or grouping

6. Double Bubble Map

used for comparing and contrasting

7. Multi-flow map

used for analyzing causes and effects

8. Bridge map

used for illustrating analogies

    

    Used for Comparing and Contrasting, the map to be introduced is the Double Bubble Map.This map is created with two Bubble Maps. Two larger circles are drawn with the things to be compared. Middle bubbles are added to show the similarities between the two. Outside bubbles are drawn to the two larger circles with words that show the differences.

Double Bubble Criteria :  Must have a number of comparison ideas (circles in between the main idea bubbles/circles in the center) . All comparison ideas (circles in the center) should be colored the same color . Must have a number of contrasting ideas (circles on the outside of main idea bubbles) on each side. Each contrasting idea must match up topic for topic across from each other (country across from country, type of religion across from type of religion, etc.) and All contrasting ideas (circles on the outside of main idea bubbles) should be colored different colors although each topic for topic idea should be colored the same color.

1.       Isolator 2.       its materials of strength 3.       hard 4.       waterproof 5.       can send heat 6.       is easy to formed

       ALUMUNIUM

   Aluminium as commercial valuable metal got from result of metallurgy ekstraksi. To get this Aluminium [is] needed [by] standard Alumina upon which which got from processing of bauxite or recognized also with process of Bayer and process of Hall-Heroult. At the moment Indonesia have owned factory forge of alumunium of[is single by electrolyte discount which [in] management by PT. Inalum ( Indonesia Grindings of Alumunium) where raw material the core important [is] alumina ( Al2O3).

IRON ( Fe )

Iron have symbol of Fe and atomic number 26. Iron represent transition metal residing in [at] faction of VIII B and period 4. Iron [is] most second best metal abundance after alumunium. Iron [is] yielded metal of iron ore, and seldom meet in a state of free element.

 Iron [is] metal coming from iron ore ( tambang) which used many for everyday human life. Besides found copious [in] nature, iron [Is] also found [by] [in] star and sun. In periodic tables, iron have symbol of Fe atom dannomor 26. Iron also have high economic value. Iron have the character of to ossify, brittlely, and generally [is] easy to mingled.

 Iron [is] metal which at most and most immeasurable its use. That thing is because several things, among others • Iron what overflows [in] big enough earth husk • Its processing relative easy to and is cheap

 Iron have the nature of modified easy and beneficial.
