5.6A

Science SE

Matter and energy. The student knows that matter has measurable physical properties that determine how matter is identified, classified, changed, and used.

Content

The student is expected to compare and contrast matter based on measurable, testable, or observable physical properties, including mass, magnetism, relative density (sinking and floating using water as a reference point), physical state (solid, liquid, gas), volume, solubility in water, and the ability to conduct or insulate thermal energy and electric energy;

Matter and Energy - Physical & Chemical Properties

3.6.A measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float in water;

3.6.B describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container;

4.6.A classify and describe matter using observable physical properties, including temperature, mass, magnetism, relative density (the ability to sink or float in water), and physical state (solid, liquid, gas);

6.6.D compare the density of substances relative to various fluids;

6.6.A compare solids, liquids, and gases in terms of their structure, shape, volume, and kinetic energy of atoms and molecules;

8.6.C describe the properties of cohesion, adhesion, and surface tension in water and relate to observable phenomena such as the formation of droplets, transport in plants, and insects walking on water;

8.6.D compare and contrast the properties of acids and bases, including pH relative to water;
