Compare habitat kinds

Compare habitat kinds using supplied evidence and a solved model.

About 12 minutes, plus any extended practice

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: freshwater habitat in the supplied record. Reference card B: tree-dominated habitat in the supplied record.
Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Fish live in the listed pond.
Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Woodpecker uses listed trees.
Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Grass-eater uses open grasses.
Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Dry-adapted lizard uses sparse vegetation.
Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Frogs use freshwater margins.
Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Bird nests in the woodland.

Learn the idea

A habitat provides resources and conditions. Different habitats support different organisms. Count the kinds actually listed, not how many individual animals appear in a picture.

Pond means freshwater habitat in the supplied record. Forest means tree-dominated habitat in the supplied record. Grassland means grass-dominated habitat in the supplied record. Desert means dry habitat in the supplied record.

For pond, look for the clue “freshwater habitat in the supplied record.” For forest, look for “tree-dominated habitat in the supplied record.” More than one process can happen in a real situation. Answer about the one described in this question.

Read or listen to the four science words and what each means. Say how the first two differ.
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.
Answer each practice question. Say which clue helped you, then check the explanation.
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 “freshwater habitat in the supplied record”; a second states “tree-dominated habitat in the supplied record.” The first fits pond and the second fits forest. 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 “freshwater habitat in the supplied record” to justify pond; do not sort by the name alone.
Distinguish forest (tree-dominated habitat in the supplied record) from a different process occurring in the same situation.

See the answer and explanation

pond

The answer is pond. In the notes, it means “freshwater habitat in the supplied record.” A habitat provides resources and conditions. Different habitats support different organisms. Count the kinds actually listed, not how many individual animals appear in a picture.

Take it further

Create one new case showing pond and one showing forest. Expected: the first explicitly shows “freshwater habitat in the supplied record”; the second explicitly shows “tree-dominated habitat in the supplied record.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.

Look for the described feature: tree-dominated habitat in the supplied record.
Compare the clue with each science word. Use only what the case tells you; do not add a new event.
