Physical States of Matter


Physical States of Matter

TEKS Objective

Students will classify matter based on physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal energy or electric energy.

Essential Understanding

The student knows that (1) matter has measurable physical properties and (2) those properties determine how matter is classified, changed and used.
