Catastrophe- Self Assessment
This unit investigates the internal structure of the Earth. There is a focus on
the formation of different types of rock and the rock cycle.
It is studied through the occurrence of some natural disasters

Catastrophe-Extended Writing Task
Igneous rocks are formed when magma cool
s
.
Liquid salol is a chemical that can be used in the laboratory to represent
magma. It melts easily when warmed and will form crystals on cooling.
Your task is to plan an investigation that discovers the effect of temperature on
the crystal size in an igneous rock.
You should:




List the chemicals and equipment you will need.
Explain using scientific words how the experiment will be carried out.
Identify the measurements that you will make.
How you will make it a fair experiment.
 Identify the risks and the control measures for the experiment.
 Design a table to record your results
