NGSS 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.

What This Standard Means
What Students Need to Do
- Students examine rock layers, fossils, and landforms to work out how a place changed over time. They compare relative order and connect each explanation to a specific clue.
What Mastery Looks Like
- Students can use layer order, fossil types, and erosion features to describe what happened first and later. They support each claim with a visible clue from a diagram, model, or photograph.
Common Misconceptions
- Students may assume upper layers are older because they see them first. They may treat fossils as exact dates or claim a river appeared only after the canyon formed.
How to Assess It
- Show a diagram with plant fossils in a lower layer, shell fossils above, and a river cutting through both. Ask students to describe two landscape changes and cite one clue for each.

Ways to Teach It
Build layers of sand, soil, leaves, and shells in a clear container, then cut a channel and record the sequence of events.
Ask students to write: What story do these rock layers tell, and which two clues support your explanation?
Play a card sort matching rock layer diagrams, landscape change claims, and evidence cards, then have partners defend each match.
Compare photographs of a local riverbank or road cut over time, and identify clues showing erosion, deposition, or changing environments.
