我们如何看见物体
How We See Objects
建立一个模型，描述光从物体反射并进入眼睛后，我们才能看见物体。
Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen
学习证据 / Evidence
- 画一张示意图，表示光源→光照射到物体→反射进入眼睛
- 解释我们看到物体是因为反射光进入我们的眼睛，而不是因为眼睛发出光
- 用这个模型解释为什么在完全黑暗中看不见东西（因为没有光可反射）
- Draw a diagram showing light source → light hits object → reflects into eye
- Explain that we see objects because reflected light enters our eyes, not because our eyes send out light
- Use this model to explain why we can't see in total darkness (no light to reflect)
