Lesson 7: Why the Sun outshines every star
Grades 3–5 · about 15 minutes · NGSS 5-ESS1-1. By the end: I can explain that the Sun looks brighter than other stars because it is so much closer.
Learn
- The Sun is an ordinary star. Some stars are smaller and dimmer; many are bigger and give out far more light.
- The Sun looks so bright because it is close: about 150 million kilometres away, so its light reaches us in about eight minutes.
- The next nearest star is about 4 light-years away: its light takes about four years to get here. That's why even giant stars look like faint dots.
Try it
In a dark room, have someone hold a flashlight close, then walk it to the far end. Same flashlight: it only looks dimmer because it's farther away.
Quiz: five questions
Four right is a pass. Peabody reads every question; tap a box.
