HS-ESS1-6
The standard
Apply scientific reasoning and evidence from ancient Earth materials, meteorites, and other planetary surfaces to construct an account of Earth's formation and early history.
Next Generation Science Standards
What this standard means
Students need to use evidence from rocks, meteorites, Moon samples, and cratered surfaces to explain how Earth formed and changed early on. They should connect radiometric ages, composition data, and crater patterns to a timeline, not just memorize dates.
Mastery looks like a clear claim about early Earth, supported by several lines of evidence from across the solar system. Students often get stuck thinking Earth’s oldest rocks equal Earth’s age, mixing up relative and absolute dating, or treating craters as random damage instead of records of impacts over time.
Ways to teach it
- Give groups data cards with meteorite ages, zircon ages, Moon rock ages, and crater images, then have them build an early Earth timeline.
- Ask students to write: Why do scientists use meteorites and Moon rocks to tell Earth’s origin story?
- Use an exit ticket where students choose the best evidence for Earth’s age from four options and justify it in two sentences.
- Connect to lunar mission samples by having students compare Apollo Moon rock ages with Earth’s oldest minerals and explain the gap.
