Crude Oil and Fractional Distillation — Interactive Lesson (Ages 14–16)

How does thick black crude oil from the Niger Delta or the North Sea become petrol, diesel and bottled gas? This 21-slide interactive lesson on fractional distillation of crude oil takes pupils from first ideas to exam-style explanations, with 12 self-marking activities and nothing to prepare beforehand.

Teaching Crude Oil and Fractional Distillation in GCSE Chemistry

Pupils learn how crude oil formed from ancient plankton, why it is a finite mixture of hydrocarbons and how fractional distillation separates it in a column that is hot at the bottom and cool at the top. They match each fraction — refinery gases, petrol, kerosene, diesel oil, heavy fuel oil and bitumen — to its uses, meet real refineries such as Dangote and Fawley, and weigh up environmental impacts including oil spills and gas flaring.

What Pupils Will Learn

• Describe how crude oil was formed.
• Explain why crude oil is a mixture that must be separated.
• Describe how fractional distillation separates crude oil.
• Name the main fractions and their uses.
• Discuss the environmental impact of using crude oil.
