IGCSE Physics: Stellar Evolution | Edexcel Modular | Unit 9 | L3 ★ FREE

This lesson covers spec points 9.9 and 9.10 of the Edexcel Modular IGCSE Physics specification — the life
cycle of a star similar to the Sun and the life cycle of a star much more massive than the Sun.

PowerPoint includes:
• Retrieval starter reviewing gravity and stellar material
• Direct Instruction (I Do) — stars as “the ultimate recyclers”; the full life cycle introduced; the main
sequence phase explained as a balance between gravity and outward pressure; the path of a solar-mass star
(nebula → main sequence → red giant → white dwarf); the path of a massive star (red supergiant →
supernova → neutron star or black hole); a stellar pathways summary comparing the two routes
• Guided Practice (We Do) — three guided tasks sequencing and comparing the two stellar life cycles, with
answers revealed
• Check for Understanding — 3 MCQs on life-cycle stages and the role of mass; answers on following slides
• Independent Practice (You Do) — activity sheet with exam-style questions
• Review and Reflect — leads into the next lesson (the HR diagram)

Activity Sheet includes:
• Exam-style questions progressing from naming life-cycle stages to comparing the fate of low-mass and
high-mass stars and explaining the role of gravity
• A stretch question on the conditions that determine a star’s final state
• Full mark scheme for teacher use
