You are going to learn why metals are so important for us and how we obtain them
This time you are going to learn it by yourself using all the information that we can find in Internet
What to you have to explain?
�Metals Classification�Metal Obtaining and processing
�Environmental impact

PURE METAL PROPERTIES APPLICATIONS
There you have to create TWO tables as you have on page 84 and 85 about metals and
PURE METAL PROPERTIES APPLICATIONS

Everything has to be in English,
but you can use
pictures instead of textsFor exampleFor example

2º ActivityOpen Office Open Office
impress
Open a new OpenOffice Impress file and make a presentation about the
metal obtaining
From minerals
tostainless steel
Lets see a small summary of the hole iron obtaining process:
Raw Materials extractionRaw Materials extraction
Chemical reaction
Purification
Cast
The chemical reaction that creates iron needs:
Raw Materials extraction
Metal minerals
ironCoal
limestone
heat
Raw Materials extraction
We get metal minerals, coal and limestone from mines around the world
furnaceRaw materials
Raw materials are introduced into the furnace with high temperatures
Slag
Iron cast
In order to obtain pure metal we need to transport the iron cast with specials containers and oxidize the mix with pure O2
specials containers
pure O2
Liquid metal is introduced into special moulds. Liquid metal fills the mould and get cold and rigid with a special shape.
3º ActivityOpen Office Open Office
Calc
Let’s study what is the metal environmental impact
You are going to be data analyst
Create a new open office calc file and copy this data:
Country CO2 emissions Energy consumed Mkw
Country CO2 emissions Tones Mkw
Spain 2000 100
France 1500 150
Germany 2500 50
Portugal 3000 75
England 3500 125
Now calculate the total amounts of CO2 and the Energy
Country CO2 emissions Tones
Energy consumed Mkw
Spain 2000 100Spain 2000 100
France 1500 150
Germany 2500 50
Portugal 3000 75
England 3500 125
TOTAL
Create a graphic that explains which country consumes more energy or emits more CO2
