太阳系（11岁以上）
The solar system (age 11+)
描述太阳系的详细结构，包括卫星、小行星和彗星；比较行星的轨道周期和距日距离；区分行星、矮行星及其他天体。
Describe the detailed structure of the solar system, including moons, asteroids, and comets, compare orbital periods and distances of the planets, and distinguish between planets, dwarf planets, and other bodies
学习证据 / Evidence
- 能按顺序说出八大行星，并给出每一颗行星的一个显著特征
- 能描述行星、矮行星、小行星和彗星之间的区别
- 能解释行星与太阳的距离和轨道周期之间的关系（离太阳越远的行星，轨道周期越长）
- Names the eight planets in order and gives one distinguishing fact about each
- Describes the difference between a planet, a dwarf planet, an asteroid, and a comet
- Explains the relationship between distance from the Sun and orbital period (planets further out take longer)
评估问题 / Assessment
如果{{name}}正在制作一个太阳系模型，他们能描述行星、卫星、小行星和彗星之间的区别，并解释为什么离太阳最近的行星完成一圈轨道所需的时间更短吗？
If {{name}} was making a model of the solar system, could they describe the difference between a planet, a moon, an asteroid, and a comet — and explain why planets closest to the Sun take less time to complete an orbit?
