SC15.2.1
Conduct an investigation to describe and classify various substances according to physical properties (e.g., milk being a liquid, not clear in color, assuming shape of its container, mixing with water; mineral oil being a liquid, clear in color, taking shape of its container, floating in water; a brick being a solid, not clear in color, rough in texture, not taking the shape of its container, sinking in water).

Knowledge
Students know:
- Different kinds of matter exists.
- Properties of both solids (opaque, transparent, translucent, rough, smooth, float, sink, has its own shape) and liquids (color, assumes shape of container, opaque, transparent, translucent).
- Many types of matter can be either solid or liquid, depending on temperature.
Skills
Students are able to:
- Plan and conduct an investigation to produce data that is used to describe and classify substances according to physical properties.
Understanding
Students understand that:
- Observable patterns in the properties of materials provide evidence to classify the different kinds of materials.
