Read Materials: Match Each Property to Evidence
Material questions are evidence-matching tasks. Translate each observation into one property before naming a material.
Material properties: compare and select is the central idea in this question pattern. Identify the condition in the stem before applying the method below.
Keep properties distinct
Solubility means dissolving in a liquid; transparency means letting light through; conductivity means allowing heat or electric current to pass; malleability means being hammered into sheets.
Use a process clue
If a substance floats or sinks, compare density with the liquid. If two liquids mix uniformly, they are miscible; if not, they form separate layers.

- ✓Write the observed property before naming a material.
- ✓Separate electrical and thermal conductivity.
- ✓Use density for floating, not mass alone.
Waterproof does not mean it cannot conduct electricity, and a conductor need not be transparent.
