The early universe made mainly hydrogen and helium, plus a little lithium. Stars later made many heavier nuclei. Main-sequence stars fuse hydrogen into helium; later stages of massive stars build heavier elements towards iron. Supernovae spread enriched material. Not every heavy element requires a supernova: neutron capture in ageing stars and neutron-star events also matters. Safety: Paper only. No heating, chemicals, radiation sources or material collection. Stop: Stop at a qualitative origin map. No nuclear-reaction experiment or exact isotope calculation.

Materials: Paper; Pencil; Six paper boxes 1. Draw six source boxes: early universe; main-sequence star; later massive-star stages; ageing-star neutron capture; explosive events and neutron-star mergers; enriched cloud forms a later planetary system. These are process categories, not a single clock-scaled timeline. 2. Write these element cards: hydrogen—mostly early universe; helium—early universe and hydrogen fusion; carbon—helium fusion in stars; oxygen—stellar fusion; iron—massive-star processes and supernova-related production; gold—rapid neutron-capture environments, including neutron-star mergers. Match cards to appropriate boxes; a card may connect to more than one. 3. Draw arrows carrying enriched material from stellar winds and supernova ejecta into the cloud box, then to a new star and planet. Write: mixing happens over long histories; a body’s atoms do not all come from one star. 4. Write a chain for the iron in a fictional person: earlier star or supernova production → material dispersed and mixed → solar-system formation → Earth → food and body. Label the person illustrative, not a measured atom history. 5. Correct two statements: all body atoms were made in stars; all elements heavier than iron need a supernova. Give the reason for each correction. Done: Finish six source boxes, all element cards, the iron chain and both corrected statements. Proof: Keep the map and corrections. Note if the adult supplied source categories or exceptions. Stop: Stop at a qualitative origin map. No nuclear-reaction experiment or exact isotope calculation.
