Star Brightness & Distance
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
Suggested ages 10–11
Learning journey
Your child is exploring how Earth fits into the solar system — understanding why the sun appears brighter than distant stars and observing patterns in shadows, day and night cycles, and seasonal changes in the sky.
Evidence of understanding
- 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
Assessment prompt
Can Star Brightness & Distance explain why the sun looks so much brighter than other stars, even though many stars are actually bigger — it's because the sun is much closer to us?
