Check understanding
- Describes the main stages in the life cycle of a star similar to the Sun: nebula → protostar → main sequence → red giant → planetary nebula → white dwarf
- Explains that more massive stars end as a supernova followed by a neutron star or black hole
- States that nuclear fusion inside stars produces heavier elements from hydrogen and helium
“If your child was told that the iron in their blood was forged inside a star that exploded billions of years ago, could they explain the life cycle of a star and how elements are made inside stars?”
