Explain an improvement with a reason
Explain an improvement with a reason 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: blocks the shown path through the roof. Reference card B: helps a sagging roof stay up.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Water enters through a roof opening.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: The roof sags in the drawing.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: The edge toy is outside the roof.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: A changed roof has no result yet.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: A center roof hole needs blocking.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: A repaired drawing needs evidence.
Learn the idea
A useful improvement connects a change to a specific problem. Draw your change and point to the expected water path. A prediction still needs a test record.
Close gap means blocks the shown path through the roof. Add support means helps a sagging roof stay up. Widen roof means covers an uncovered edge. Retest means checks the changed drawing against the goal.
For close gap, look for the clue “blocks the shown path through the roof.” For add support, look for “helps a sagging roof stay up.” 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.
See the method in action
Worked reference-card problem: a card states “blocks the shown path through the roof”; a second states “helps a sagging roof stay up.” The first fits close gap and the second fits add support. 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 “blocks the shown path through the roof” to justify close gap; do not sort by the name alone.
- Distinguish add support (helps a sagging roof stay up) from a different process occurring in the same situation.
See the answer and explanation
close gap
The answer is close gap. In the notes, it means “blocks the shown path through the roof.” A useful improvement connects a change to a specific problem. Draw your change and point to the expected water path. A prediction still needs a test record.
Take it further
Create one new case showing close gap and one showing add support. Expected: the first explicitly shows “blocks the shown path through the roof”; the second explicitly shows “helps a sagging roof stay up.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
