恒星亮度与距离
Star Brightness & Distance
支持一个论点：太阳和星星的视亮度取决于它们与地球的相对距离，并理解太阳是一颗相对较近的恒星。
Support an argument that the apparent brightness of the sun and stars is due to their relative distances from Earth, understanding the sun is a relatively close star
学习证据 / Evidence
- 解释太阳是一颗恒星，它看起来亮得多是因为它离地球近得多。
- 描述手电筒在近处看起来更亮、在远处看起来更暗的类比。
- 论证星星的视亮度差异主要源于它们与地球的距离不同。
- Explain that the sun is a star, and it appears much brighter because it is much closer to Earth
- Describe how a torch looks brighter close up and dimmer far away as an analogy
- Argue that differences in apparent brightness of stars are mainly due to their different distances from Earth
