What you will learn

Weathering changes or breaks material in place. Erosion removes or transports it. Deposition happens when carried material settles. These processes can repeat.

Words to use

  • weathering: breaking or changing in place
  • erosion: removal or transport
  • deposition: settling

Evidence for this lesson

Scene A: a crack grows and a piece separates from a rock in place. Scene B: flowing rainwater carries the loose piece down a small channel. Scene C: water slows and the piece rests in a pile.

Use the supplied record as written; do not invent missing results.

Work through the activity

  1. 5 min · Read the storyRead all three scene descriptions below. Point to the action in each scene rather than guessing from one word.
  2. 10 min · Match processesWrite a process word beside each scene. Explain whether the material stayed in place, moved or came to rest.
  3. 10 min · Build a sequenceDraw three panels for the story. Use arrows to show that pieces formed before being moved and later settled.
  4. 10 min · Ask what comes nextImagine another storm after the pile formed. Tell a partner why deposited pieces could move again.

Grade 2 · Break, Move, Settle

Learning goal: Put weathering, erosion and deposition into an evidence-based sequence.

Expected responses

  1. Scene A: a crack forms and a fragment separates at the rock face.
  2. Scene B: rainwater carries the fragment away.
  3. Scene C: the fragment rests where flowing water slows.
  4. Yes. A later flow or another agent may move deposited material again.

Understanding check: Deposition. The fragment coming to rest is deposition. Its earlier movement was erosion.

Watch for this misconception

Weathering and erosion are related but describe different actions.

Assess the evidence

Look for the observations, calculation or explanation named in the learning goal. Accept accurate drawings and dictated responses. Use the expected responses to discuss reasoning; a correct guess without explanation is a starting point for another conversation.

Adapt and extend

Read prompts aloud, enlarge print or let a partner record the learner’s explanation. Write another three-scene story using wind as the transport agent.
