| Law of Conservation of Mass | conservation of mass: a fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system. |
| Physical Change | phase change: a change from one state (solid or liquid or gas) to another without a change in chemical composition. |
| Chemical Change | chemical process: (chemistry) any process determined by the atomic and molecular composition and structure of the substances involved. |
| Element | component - cell - constituent - factor |
| Chemical Formula | formula: a representation of a substance using symbols for its constituent elements. |
| Element (Diatomic) Molecule | Diatomic molecules are molecules composed only of two atoms, of either the same or different chemical elements. |
| Compound Molecule | A process that involves rearrangement of the molecular or ionic structure of a substance. |
| Chemical Equation | A chemical equation is symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and right side. |
| Chemical Reaction | A process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form. |
| Reactants (in a chemical equation) | A substance that takes part in and undergoes change during a reaction. |
| SPEED | Rapidity of movement or action: "excessive speed"; "the speed of events". |
| VELOCITY | The speed of something in a given direction. |
| ACCELERATION | Increase in the rate or speed of something. |
| FORCE | A push or a pull |

| GOGGLES | Look with wide open eyes, typically in amazement or wonder. |
