In fifth grade, students learn about the physical properties of matter, including magnetism, physical states of matter, relative density, solubility in water, and the ability to conduct or insulate electrical and heat energy. Students explore the uses of light, thermal, electrical, and sound energies.
Students also begin to develop an advanced understanding of how certain types of questions can be answered by investigations, and they learn that methods, models, and conclusions built from these investigations change as new observations are made.
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.
