Scientific knowledge has changed peoples’ understanding of the world and is refined as new evidence becomes available (ACSHE119)

Elaborations
  • investigating how advances in telescopes and space probes have provided new evidence about space
  • researching different ideas used in the development of models of the solar system developed by scientists such as Copernicus, Khayyám and Galileo
  • researching developments in the understanding of astronomy, such as the predictions of eclipses and the calculation of the length of the solar year by Al‑Battani in the tenth century
