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