Material Classification Skill

When to Use

Activate when direct experimental testing of a material property (conductivity, magnetism, etc.) fails or equipment is unavailable, and you need to classify the material by inference to complete a sorting task.

Procedure

1. focus on <OBJECT> — identify the target and note its material composition.
2. Attempt direct testing if equipment exists (e.g., connect <OBJECT> terminal 1 to <WIRE> terminal 2).
3. If testing fails, infer the property from the object's material. Consult references/material_properties.md for lookup.
4. move <OBJECT> to <CONTAINER> — place in the appropriate classification container.
5. look at <CONTAINER> — verify the object was placed correctly.

Example

Task: Classify a glass jar for electrical conductivity when the circuit test is unavailable.

1. focus on glass jar
2. connect glass jar terminal 1 to yellow wire terminal 2 — action fails (invalid connection).
3. Inference: glass is an electrical insulator → non-conductive.
4. move glass jar to orange box
5. look at orange box — observation: "containing a glass jar" — classification complete.
