Materials by property
Verbatim workbook outcome: Compare and group materials by properties (hardness, conductivity, solubility). · Trace: GROW Weekly - Spring!C28
Objective: Compare supplied materials by hardness, conductivity and solubility, using observations to justify each grouping.
Success evidence:
- Compare supplied materials by hardness, conductivity and solubility, using observations to justify each grouping.
- A material can belong to different groups for hardness, conductivity and solubility because each property asks a different question.
- One classroom result supports a cautious grouping for those materials and conditions; it does not define every material everywhere.

Truth boundary: never backdate, never reconstruct a quotation, never stage an event, and never convert adult wording into the learner’s voice. Use only school-approved local materials. No diagnosis or medical advice. No personal or family disclosure. Learning does not depend on a runtime connection. No open runtime link. Never invent a result, date, quotation, event, audience response or learner wording. Use only school-approved local sources and supplied classroom materials. No open runtime link.

Vocabulary in use
- HARDNESS in three evidence-led material groupings: resistance to scratching under the named comparison. Apply HARDNESS when this anchor matters—A material can belong to different groups for hardness, conductivity and solubility because each property asks a different question.—and check it beside this second anchor: A fair comparison keeps the test method and conditions the same for every supplied material.
- CONDUCTIVITY in three evidence-led material groupings: ability to let electrical energy transfer in the supplied low-voltage test. Apply CONDUCTIVITY when this anchor matters—A fair comparison keeps the test method and conditions the same for every supplied material.—and check it beside this second anchor: An observation such as a circuit indicator, scratch comparison or visible dissolving is recorded before the property label.
- SOLUBILITY in three evidence-led material groupings: whether a substance dissolves in a named solvent under stated conditions. Apply SOLUBILITY when this anchor matters—An observation such as a circuit indicator, scratch comparison or visible dissolving is recorded before the property label.—and check it beside this second anchor: One classroom result supports a cautious grouping for those materials and conditions; it does not define every material everywhere.
Use a supplied material card and three separate property columns. For hardness, compare the named scratch evidence without damaging unknown material. For conductivity, read the approved low-voltage circuit record rather than using mains electricity. For solubility, distinguish visible dissolving from particles settling or remaining. Place the material in each column with an observation locator and a cautious reason.

For conductivity, read the approved low-voltage circuit record rather than using mains electricity. For solubility, distinguish visible dissolving from particles settling or remaining. Place the material in each column with an observation locator and a cautious reason. Compare the approved material set across three property questions. Use supplied observations or teacher-approved demonstrations, retain the method and conditions, and group the materials separately for hardness, conductivity and solubility. Record at least one material that changes group when the property changes. Finish by identifying which grouping has the strongest observation and which needs a repeat or authorised check.
