C1 independent study
task.
5
Settler: list the order of fractions in a
fractional distillation column (start with
bitumen at the bottom and gases at the top)
Challenge:
•How are the fractions separated?
•Give a use for each fraction.
• list the changes in properties that occur as you go down
the column
Choose your own tasks 
Answer all the questions and then get a lead
learner near you to check your answers with red
pen.
