4-ESS1-1
The standard
Identify evidence from patterns in rock formations and fossils in rock layers to support an explanation for changes in a landscape over time.
Next Generation Science Standards
What this standard means
Students need to use clues in rock layers and fossils to explain how a place changed over time. They should notice patterns, such as shells found above plant fossils, or layered canyon walls with a river below. They are not naming rock types or memorizing famous formations.
Mastery looks like a student saying, “This area was land first, then covered by water,” and pointing to evidence. Students often get stuck thinking all layers formed at once, or that deeper layers are newer. They also may describe the picture without using it to support a time-order explanation.
Ways to teach it
- Give pairs a stacked paper strip model with fossil symbols, then have them place event cards in oldest-to-newest order.
- Ask students to write: What changed in this landscape, and what evidence in the layers proves it?
- Show a canyon diagram and ask students to circle two clues, then write one sentence explaining the past landscape.
- Use a local road cut, stream bank photo, or park rock image to discuss how layers can show past environments.
