Watch presentation_001. Now write down one thing you know about fossil fuels Share your answer with a partner. Pairs feed back one of their answers to the rest of the class, passing if their answer has already been given. Fossil fuels were formed from the remains of dead plants and animals, that lived million of years ago. Burning fossil fuels - gases
Natural gas (methane) is a fossil fuel. LPG Propane and butane are the liquefied petroleum gases (LPG) most commonly used. Propane has a variety of uses, including heating homes, and as a fuel for vehicles. Butane is sold as camping gas. Demonstration Burning fossil fuels
Petrol, paraffin and diesel are examples of liquid fossil fuels. Coal is a solid fossil fuel. Task 1: Answers What are fossil fuels?
Name the fossil fuels mentioned so far (7). Fossil fuels were formed from the remains of dead plants and animals, that lived million of years ago. Natural Gas (Methane), LPG (Propane), Camping Gas (Butane), Petrol, Paraffin, Diesel and Coal How can I improve on task 1?

Task 2 (Grade B) Task 2: Describe: How crude oil is separated into fractions The main fractions obtained from crude oil Task 2: Extension Keywords for Task 2: hydrocarbons non-renewable resource finite resource New Information for Task 2
Crude oil is: the source of liquid fossil fuels. a mixture of hydrocarbons. a non-renewable resource. a finite resource. Explain what the words in WHITE mean. Hydrocarbons are compounds made from hydrogen and carbon ONLY. Crude oil is a non-renewable resource, because
.. it has taken millions of years to form from the remains of plants and animals. Renewable resources must be .. replaceable within a reasonable amount of time (days to years). Crude oil is a finite resource, because .. there is only so much of it on planet earth, and eventually it will be all used up. Fractional distillation of crude oil
Small molecules: Low boiling points Very volatile Flows easily Ignites easily LPG Petrol Crude oil is a mixture of HYDROCARBONS and these can be separated due to differences in their BOILING POINTS. Large molecules: high boiling points not very volatile viscous does not ignite easily Note: this may not match that given in the text book Task 2: Summary Copy and complete:
Crude oil is a mixture of many different hydrocarbons. Crude oil is separated by fractional distillation. Fractions containing mixtures of hydrocarbons are obtained. Each fraction contains many substances with similar boiling points. 2. The fractions collected from the cooler top to the hotter bottom of the fractional distillation column are: LPG, petrol, paraffin, diesel, heating oil, fuel oil, bitumen Use their first letters to make a rhyme to help you remember them.
