(5.5) Properties of Matter
At this point in elementary school, students engage in more sophisticated investigations of different materials. They become familiar with concepts related to 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. They use a variety of tools, such as thermometers, calculators, metric rulers and stop watches, to collect data.
Students will identify the boiling and freezing/melting points of water on the Celsius scale.
