Supplied materials

  • For younger learners, an adult may read each direction aloud; pointing, drawing and spoken explanations count as responses.
  • Paper, drawing space or a browser document.
  • Reference card A: surface without noticeable bumps. Reference card B: surface with noticeable bumps.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: A card says surface has no bumps.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: A card says surface has many bumps.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: A cushion yields to a gentle press.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: A block resists a gentle press.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: A surface is described as bumpy.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: A pad is easily squashed.

Learn the idea

Use supplied descriptions, not touching unknown objects. A property is something you can describe. Two objects may share one property and differ in another.

Smooth means surface without noticeable bumps. Rough means surface with noticeable bumps. Soft means changes shape easily when pressed. Hard means resists a gentle press.

For smooth, look for the clue “surface without noticeable bumps.” For rough, look for “surface with noticeable bumps.” More than one process can happen in a real situation. Answer about the one described in this question.

  1. Read or listen to the four science words and what each means. Say how the first two differ.
  2. Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
  3. Answer each practice question. Say which clue helped you, then check the explanation.
  4. Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.
Worked example

See the method in action

Worked reference-card problem: a card states “surface without noticeable bumps”; a second states “surface with noticeable bumps.” The first fits smooth and the second fits rough. The reason is the described function or change, not the order of the cards or a favorite name. If their descriptions exchange places, their category labels exchange too. Keep the supplied descriptions attached to the correct case.

Helpful tips
  • Use the feature “surface without noticeable bumps” to justify smooth; do not sort by the name alone.
  • Distinguish rough (surface with noticeable bumps) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: A card says surface has no bumps.

smooth

The answer is smooth. In the notes, it means “surface without noticeable bumps.” Use supplied descriptions, not touching unknown objects. A property is something you can describe. Two objects may share one property and differ in another.

Take it further

Create one new case showing smooth and one showing rough. Expected: the first explicitly shows “surface without noticeable bumps”; the second explicitly shows “surface with noticeable bumps.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

More practice: try new cases

Choose an answer for each problem. Explain your method on paper, then use the feedback to decide what to revisit.

More practice: try new cases
1. Which scientific label fits the specifically described step or feature? Supplied case: A card says surface has many bumps.
Need a hint?
  • Look for the described feature: surface with noticeable bumps.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
2. Which scientific label fits the specifically described step or feature? Supplied case: A cushion yields to a gentle press.
Need a hint?
  • Look for the described feature: changes shape easily when pressed.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
3. Which scientific label fits the specifically described step or feature? Supplied case: A block resists a gentle press.
Need a hint?
  • Look for the described feature: resists a gentle press.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
