Solids and Liquids

Solids and Liquids

TEKS Objective

Classify matter by physical properties, including shape, relative mass, relative temperature, texture, flexibility, and whether material is a solid or liquid.


Essential Understanding

The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.
