5-ESS1-1
The standard
Support an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from Earth.
Next Generation Science Standards
What this standard means
Students need to explain why the Sun looks much brighter than other stars even though it is also a star. They should use evidence about distance, not guesses about size, heat, or power, to support a clear claim.
Mastery looks like a student saying, “The Sun appears brightest because it is much closer to Earth,” then backing that up with a model, data table, or comparison. Students often get stuck thinking the Sun is the biggest star, or that all bright objects must give off more light.
Ways to teach it
- Use flashlights at different distances in a dim room, then have students record which light appears brighter and why.
- Ask students to write a claim, evidence, reasoning response explaining why the Sun looks brighter than nighttime stars.
- Show three object distance examples and ask students to choose which would appear brightest, then explain in one sentence.
- Compare a nearby streetlight with a faraway stadium light to show how distance changes how bright something looks.
