Science | 4 | Physical Science | 4.PS.1 | Electricity, Heat and Matter | When objects break into smaller pieces, dissolve, or change state, the total amount of matter is conserved. When an object is broken into smaller pieces, when a solid is dissolved in a liquid or when matter changes state (solid, liquid, gas), the total amount of matter remains constant. |
Science | 6 | Physical Science | 6.PS.2 | Matter and Motion | Changes of state are explained by a model of matter composed of particles that are in motion. When substances undergo changes of state, atoms change their motion and position. |
