Explain a shade model
Explain a shade model 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: upper cover blocking the shown light. Reference card B: support holding up the cover.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Label the top cover.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Label the upright support.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Label the opening between sheets.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Label the surface below.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: Label a stick holding the roof.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Label an uncovered opening.
Learn the idea
A roof can block light above an area. An open roof edge can still let light reach part of the ground. Draw the light path; a model is simpler than a real place.
Roof means upper cover blocking the shown light. Post means support holding up the cover. Gap means opening allowing the shown light through. Ground means surface being protected.
For roof, look for the clue “upper cover blocking the shown light.” For post, look for “support holding up the cover.” 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 “upper cover blocking the shown light”; a second states “support holding up the cover.” The first fits roof and the second fits post. 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 “upper cover blocking the shown light” to justify roof; do not sort by the name alone.
- Distinguish post (support holding up the cover) from a different process occurring in the same situation.

roof
The answer is roof. In the notes, it means “upper cover blocking the shown light.” A roof can block light above an area. An open roof edge can still let light reach part of the ground. Draw the light path; a model is simpler than a real place.
Take it further
Create one new case showing roof and one showing post. Expected: the first explicitly shows “upper cover blocking the shown light”; the second explicitly shows “support holding up the cover.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
