C1.23 - Crude Oil and start of Distillation column.ppt
- 1. 28/04/2024 Crude Oil - a new topic Lesson success criteria? Understand that crude oil is a mixture of hydrocarbon molecules. Know that hydrocarbons are compounds that contain carbon and hydrogen only. Describe crude oil as a fossil fuel and recall its formation. Be able to explain the reasons for fraction isolation in terms of boiling point and carbon chain Objective: By the end of the lesson I will be able to describe what crude oil is and recall its uses, so that? On your whiteboards: Get into the fossil fuels groove Mind map What are fossil fuels and how are they formed? THINK: Capital- full sentence- full stop!

- 3. 28/04/2024 Produce a flowchart in your books to show how crude oil was formed Use just 10 words and quick sketches 15 mins Support? Target is C or below? Use up to 13 words THINK: Capital- full sentence- full stop!
- 4. 28/04/2024 So, what is crude oil? Crude oil is a mixture of molecules called HYDROCARBONS. On your whiteboards - which 2 elements make up hydrocarbons?

- 6. 28/04/2024 Hydrocarbon or not? What is a hydrocarbon then? Write your own definition of this keyword What is a hydrocarbon then? A compound with only Carbon and hydrogen bonded THINK: Capital- full sentence- full stop!
- 7. Fractional distillation of crude oil: part 1 Lesson Objectives Recallthat crude oil is a mixture of hydrocarbon molecules. Describethat hydrocarbons are compounds that contain carbon and hydrogen only Be able to explain the reasons for fraction isolation in terms of boiling point and carbon chain length. Lesson Menu Hydrocarbon formation. Testing your memories Classifying your terms The fractional distillation column Retest knowledge. THINK: Capital- full sentence- full stop!

- 12. In pairs One faces the board (person A) The other sits with their back to them (person B) Person A is going to describe a fractional distillation column to person B. Person B: Youre going to draw it. You have 4 minutes to get as much detail in as you can. A prize for the best diagram! Person B - NO LOOKING! THINK: Capital- full sentence- full stop!

- 14. Have a look at the board How did you do with the diagram? Top of the fractional distillation column has the short chained Hydrocarbon molecules that are very volatile, with low boiling points and therefore ignite very easily! Less viscous. Hottest point of the column is the bottom, where thick dense long chain molecules remain. Opposite properties than top of column! THINK: Capital- full sentence- full stop!
- 15. New page Individually - 4 minutes to draw the column. Identify each fraction. Put fractions in the correct order. Link each fraction to a use Prize/ star for the best image!! THINK: Capital- full sentence- full stop!
