Build different objects from parts
Build different objects from parts 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: one separate building part. Reference card B: parts arranged into a whole.
- Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: One paper rectangle.
- Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: Three rectangles arranged as a bridge.
- Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: Bridge is intended to span a gap.
- Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: Rectangles become a wall afterward.
- Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: A single joining tab.
- Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: Wall’s job is divide spaces.
Learn the idea
The same components can form different structures. Count what parts are used and describe their arrangement. Shape can change an object’s function without changing the material.
Component means one separate building part. Structure means parts arranged into a whole. Function means what the object is intended to do. Reuse means use the same part in another arrangement.
For component, look for the clue “one separate building part.” For structure, look for “parts arranged into a whole.” 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 “one separate building part”; a second states “parts arranged into a whole.” The first fits component and the second fits structure. 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 “one separate building part” to justify component; do not sort by the name alone.
- Distinguish structure (parts arranged into a whole) from a different process occurring in the same situation.

component
The answer is component. In the notes, it means “one separate building part.” The same components can form different structures. Count what parts are used and describe their arrangement. Shape can change an object’s function without changing the material.
Take it further
Create one new case showing component and one showing structure. Expected: the first explicitly shows “one separate building part”; the second explicitly shows “parts arranged into a whole.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
