Mastery Evidence
- Describe the geocentric model (Earth at the centre) and name Ptolemy as its main proponent
- Describe the heliocentric model (Sun at the centre) and name Copernicus as the person who proposed it
- Explain that Galileo used a telescope to find evidence supporting the heliocentric model (e.g. moons orbiting Jupiter)
