关于太空的观念变化
Changing Ideas About Space
了解人类关于太阳系的认识是随着时间变化的：古代人认为地球是宇宙的中心（地心说，由 Ptolemy 提出），直到 Copernicus 提出太阳才是中心（日心说），后来 Galileo 用望远镜观测证实了这一观点。
Understand that ideas about the solar system changed over time: ancient people believed Earth was at the centre (geocentric model, Ptolemy), until Copernicus proposed the Sun was at the centre (heliocentric model), later confirmed by Galileo’s telescope observations
学习证据 / Evidence
- 描述地心说（地球在中心），并说出其主要提出者是 Ptolemy。
- 描述日心说（太阳在中心），并说出 Copernicus 是提出这一观点的人。
- 解释 Galileo 如何用望远镜找到支持日心说的证据（例如木星周围有卫星环绕）。
- 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)
