1. What do these have in common?

2. Crude Oil

3. Our Learning Objectives recall that crude oil is a complex mixture of hydrocarbons describe how the process of fractional distillation can be used to separate the hydrocarbons in crude oil into the fractions refinery gases, gasoline, kerosene, diesel, fuel oil and bitumen describe the physical properties and uses of the main fractions recall that fractional distillation of crude oil produces more long-chain and fewer short-chain hydrocarbons than required

4. How did it get there? Put these sentences into the right order: Millions of tiny animals lived in the seas The pressure and heat of the rocks turned the dead animals into oil As the dead animals decayed they were covered with thick layers of mud and sand (sediment) When the animals died their bodies fell to the bottom of the sea The layers of mud slowly changed into layers of rock

5. How did it get there? Why didn’t the plant material rot away? Why do we find oil wells under both land and sea? Oil is a fossil fuel – remains of plants and animals that lived millions of years ago. Non-renewable Formation animation

6. Crude oil (Petroleum) A mixture of hydrocarbons (compounds which contain only hydrogen and carbon atoms) Copy please

7. How do we separate Crude Oil into useful parts? Simple Distillation diagram

8. How do we separate Crude Oil into useful parts? How does simple distillation work? Include the following words in your answer: Heat energy Boiling point Evaporating Condensing Fraction

9. Fractional distillation Now let’s apply your knowledge – how does this work? animation

10. Fractional distillation The mixture can be split into simpler fractions by fractional distillation (animation)animation

11. The properties of the fractions interactive fractions weblink

15. Check! Can you: recall that crude oil is a complex mixture of hydrocarbons describe how the process of fractional distillation can be used to separate the hydrocarbons in crude oil into the fractions refinery gases, gasoline, kerosene, diesel, fuel oil and bitumen describe the physical properties and uses of the main fractions recall that fractional distillation of crude oil produces more long-chain and fewer short-chain hydrocarbons than required
