Science Year 9 - Unit 2 - Lesson 12
Crude Oil and Separation Into Useful Products
1. Key Ideas
This lesson explains crude oil as a natural raw resource and shows how it can be separated into useful hydrocarbon products. The key Stage 5 idea is that crude oil is not one pure substance, but a mixture that can be separated into fractions with different uses.
- crude oil is a natural resource and a mixture of hydrocarbons
- different hydrocarbon sizes and boiling ranges help explain why separation is possible
2. Success Criteria
By the end, you should be able to:
- crude oil is a natural resource and a mixture of hydrocarbons
- crude oil can be separated into fractions with different uses
- major product types include gases, fuels, lubricants and bitumen

5. Short Answer Questions
1. Explain this lesson goal in your own words: "crude oil is a natural resource and a mixture of hydrocarbons". Use one specific example from the lesson.
2. Apply this idea to a new example: "crude oil can be separated into fractions with different uses". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Crude Oil and Separation Into Useful Products: "major product types include gases, fuels, lubricants and bitumen".
6. Extend: Apply the Idea
A student says, "I understand Crude Oil and Separation Into Useful Products because I memorised the definition."
Explain why memorising a definition is not enough. Use an example from the lesson to show deeper understanding.
