太阳系的尺度
Scale of the Solar System
利用比例模型、示意图或计算来表现太阳系中天体的相对大小和距离，理解行星之间的距离远比行星本身大得多。
Use scale models, diagrams, or calculations to represent the relative sizes and distances of objects in the solar system, understanding that the distances between planets are enormously larger than the planets themselves
学习证据 / Evidence
- 能说明如果太阳只有一个沙滩球那么大，地球就会像一粒豌豆，在约26米之外。
- 能说出行星之间的距离远比行星本身的尺寸要大得多。
- 能制作或解读一个同时体现相对大小和距离的比例模型。
- Explain that if the Sun were the size of a beach ball, Earth would be a pea about 26 metres away
- State that the distances between planets are much greater than the sizes of the planets themselves
- Create or interpret a scale model showing both relative sizes and distances
评估问题 / Assessment
{{name}}有没有亲手制作或看过太阳系的比例模型？{{name}}能否解释，为什么这些行星需要分散到整个操场上，才能保持正确的距离比例？
Has {{name}} ever built or looked at a scale model of the solar system? Can they explain why the planets would need to be spread across a whole playing field to be the right distance apart?
