About the Item


Summary:

Most landscapes include buildings such as houses, factories, flats or skyscrapers. Many of these bu
ildings are made from raw
materials found in or on the Earth’s surface. The removal of the raw materials and their use has an enormous impact on the en
vironment.

EXPECTATIONS
at the end of this project

To achieve

High Demand:

Red Route

Explain why granite, marbl
e and limestone have different hardness:



limestone is a sedimentary rock;



marble is a metamorphic rock made by the action of high pressures and temperatures on limestone;



granite is an igneous rock.

State that the balanced symbol equation for the decomposi
tion of limestone is:

CaCO
3




CaO + CO
2

Explain why reinforced concrete is a better construction material that non
-
reinforced concrete:



hardness of the concrete;



flexibility and strength of the steel.

To achieve

Standard Demand:

Yellow Route





Stat
e that some construction materials are manufactured from rocks in the Earth’s crust:



aluminium and iron from ores;



brick from clay;



glass from sand.

Describe that marble is much harder than limestone.

Describe that granite is harder than marble.

State that

the word equation for the decomposition of limestone is:

calcium carbonate

calcium oxide +carbon dioxide.


To achieve

Low Demand:

Blue and Green Route




State the names of some construction materials:



aluminium and iron;



brick, cement, concrete and glas
s;



granite, limestone and marble.

State that some rocks are used to construct buildings:



granite, limestone and marble.

Describe the environmental problems that may be caused by removing rocks from the ground:



landscape destroyed and has to be reconstructe
d when the mining or quarrying has finished;



quarries or mines take up land
-
space;



increased noise, traffic and dust.

State that limestone and marble are both forms of calcium carbonate.

Describe that limestone thermally decomposes to make calcium oxide an
d carbon dioxide.

Describe that concrete is made when cement, sand or gravel and water are mixed together and allowed to set.

Describe that concrete can be reinforced, which is made by allowing the concrete to set around a steel support.
