💡 Exam Tips for Life Cycle of Stars
🎯 Common Question Types:
- Sequence the stages of a star's life [4 marks]
- Explain main sequence stability [2-3 marks]
- Explain what happens when the Sun's hydrogen runs out [3 marks]
- State where elements heavier than iron are formed [1-2 marks]
- Compare sun-like vs massive star paths [3-4 marks]
📝 Key Command Words:
- Sequence/Arrange — put stages in correct order
- Describe — say what happens at each stage
- Explain — give the physics reason (force balance)
- State — brief answer, no explanation needed
- Compare — use the same stages for both paths side by side
⚠️ Common Mistakes to Avoid:
- Saying the Sun will become a supernova — it will NOT, it is not massive enough
- Confusing red giant with red supergiant — these are different stages for different mass stars
- Saying all heavy elements are formed in supernovae — elements up to iron are made in normal stellar fusion
- Missing "planetary nebula" from the sun-like star path
- Not starting both paths with nebula and protostar
