What you will learn

Sediment is loose natural material such as sand. Moving water can carry it; when material comes to rest, it is deposited.

Words to use

  • sediment: loose pieces
  • move: change place
  • settle: come to rest

Evidence for this lesson

No-demo example: sand starts beside a small water channel. After a pour, some sand is farther along the channel and rests in a small pile.

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

Work through the activity

  1. 5 min · Set upAn adult places damp sand at one end of a flat spill tray. Point to where the sand is before adding water. Draw that starting position.
  2. 10 min · WatchAn adult slowly pours a little water beside the sand. Watch from a safe distance. Describe which pieces moved and where they stopped; no blowing or splashing.
  3. 10 min · CompareDraw the tray after the pour. Use arrows for movement and circles for places where sand settled. If no movement happened, record that honestly.
  4. 5 min · Tell the storyExplain “Before …, then …, now …”. An adult collects used sand for disposal outside the sink.

Grade 1 · Water Moves Tiny Pieces

Learning goal: Observe water moving loose sediment and identify a place where it settles.

Expected responses

  1. A starting position in the tray should be recorded.
  2. Some sand may move with water; amounts vary with the setup. A no-movement result is acceptable.
  3. Accept a location supported by observation rather than a fixed expected shape.
  4. A prediction about more movement or settling is acceptable if explained.

Understanding check: settling. Resting sand is deposited sediment. It does not become rock just because the water stops.

Watch for this misconception

This tray is a small model. It does not show every part of a real stream.

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. Look at a photograph of sediment beside a puddle and ask what might have moved it.
