生物的生命周期
Life Cycles of Organisms
通过建立模型来描述：生物有各自独特多样的生命周期，但都包含出生、成长、繁殖和死亡这些共同阶段。
Develop models to describe that organisms have unique and diverse life cycles but all share the common stages of birth, growth, reproduction, and death
学习证据 / Evidence
- 描述至少两种不同生物（如蝴蝶、青蛙、植物）的生命周期。
- 识别所有生命周期共有的阶段：出生、成长、繁殖、死亡。
- 解释生命周期可以看起来非常不同（如变态发育与逐渐成长），但都遵循相同的模式。
- Describe the life cycle of at least two different organisms (e.g. butterfly, frog, plant)
- Identify the common stages all life cycles share: birth, growth, reproduction, death
- Explain how life cycles can look very different (metamorphosis vs gradual growth) but follow the same pattern
评估问题 / Assessment
{{name}}能比较蝴蝶和青蛙的生命周期，并解释它们共有的阶段——出生、成长、繁殖和死亡吗？
Can {{name}} compare the life cycle of a butterfly with that of a frog and explain what stages they all share — being born, growing, having babies, and dying?
