RC1: Matter & Energy [SW1]

5.5(A)  classify matter based on measurable, testable, and observable physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating using water as a reference point), solubility in water, and the ability to conduct or insulate thermal energy or electric energy

5.5(B)  demonstrate that some mixtures maintain physical properties of their ingredients such as iron filings and sand or sand and water

5.5(C)  identify changes that can occur in the physical properties of the ingredients of solutions such as dissolving salt in water or adding lemon juice to water

3.5(C)  predict, observe and record changes in the state of matter caused by heating or cooling such as ice becoming liquid water or condensation forming on the outside of a glass of ice water or liquid water being heated to the point of becoming water vapor
