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:
used for defining in context
used for describing with adjectives
used for sequencing and ordering events
used for identifying part/whole
relationships
used for classifying or grouping
used for comparing and contrasting
used for analyzing causes and effects
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.

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.

Hi dara, Please explain to me about the most specific difference between Al and Fe
BalasHapus1. Fe : metal owning whitish dusty colour, nature of is weight, quickening rustiness. while
Hapus2. Al : metal with white colour more silver, nature of is light, and hold up to corrosion.
Hi dara ...What character is typical of both elements ?
BalasHapusFe is faster to react than Al. For example, Al is resistant to corrosion while Fe does not.
Hapuswhy Fe and Al are easy to formed? Explain it!
BalasHapusBecause the two elements are in a free environment in a stable state, so that element is easy to bind with other elements to achieve stability.
HapusWhat is the difference between aluminium and iron based on its chemical properties?
BalasHapusAluminium is a good electricity conductor. Light and strong. Is a good conductor also make heat. Can be forged into sheets, pulled into wires and extruded into bars with various cross sections and Corrosion resistant. while Fe The metal is easily soluble in dilute acids. Iron is a chemically active element and forms the two main series of chemical compounds, bivalent iron (II) or ferrous, and trivalent (III) or ferrous metal compounds.
