Supplied materials

  • All measurements and observations below are supplied classroom examples. They are not data from actual learners or a claim about a particular real site.
  • Paper, drawing space or a browser document.
  • Reference card A: absorbs water and dissolved minerals. Reference card B: transports and supports.
  • Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Water uptake from soil.
  • Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Water movement upward through plant.
  • Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Light captured in green tissue.
  • Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Reproductive pollen structures.
  • Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Underground uptake tissue.
  • Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Plant support connecting roots and leaves.

Learn the idea

Parts work together in a plant system. Roots absorb water, stems transport, leaves capture light and many flowers participate in reproduction. A part’s function is more useful than its appearance alone.

Root means absorbs water and dissolved minerals. Stem means transports and supports. Leaf means captures light for food production. Flower means participates in flowering-plant reproduction.

For root, look for the clue “absorbs water and dissolved minerals.” For stem, look for “transports and supports.” 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 “absorbs water and dissolved minerals”; a second states “transports and supports.” The first fits root and the second fits stem. 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.

Your turn

Check your reasoning

Your answer is temporary and is not saved to an account. Download your current answer before leaving or reloading. Written work on paper or in another app stays in your own file.

Helpful tips
  • Use the feature “absorbs water and dissolved minerals” to justify root; do not sort by the name alone.
  • Distinguish stem (transports and supports) from a different process occurring in the same situation.
Which scientific label fits the specifically described step or feature? Supplied case: Water uptake from soil.

See the answer and explanation

root

The answer is root. In the notes, it means “absorbs water and dissolved minerals.” Parts work together in a plant system. Roots absorb water, stems transport, leaves capture light and many flowers participate in reproduction. A part’s function is more useful than its appearance alone.

Take it further

Create one new case showing root and one showing stem. Expected: the first explicitly shows “absorbs water and dissolved minerals”; the second explicitly shows “transports and supports.” 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: Water movement upward through plant.
Need a hint?
  • Look for the described feature: transports and supports.
  • 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: Light captured in green tissue.
Need a hint?
  • Look for the described feature: captures light for food production.
  • 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: Reproductive pollen structures.
Need a hint?
  • Look for the described feature: participates in flowering-plant reproduction.
  • Compare the clue with each science word. Use only what the case tells you; do not add a new event.
