| Element | a substance that can't be broken down by non-nuclear reactions |
| Mixture | a combination of two or more substances in any proportions. |
| Heterogenous Mixture | a mixture in which the composition is not uniform throughout the mixture |
| Freezing Point | point at which something freezes |
| Solution | a homogenous mixture of two or more substances in relative amounts that can be varied |

| Mass | Mass is a measure of the amount of matter in an object |
| Atoms | An atom is the basic building block of chemistry. |
| Extraction | "Extraction" refers to transference of compound(s) from a solid or liquid into a different solvent or phase. |
| Physical Property | A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. |
| Physical Change | Physical changes are limited to changes that result in a difference in display without changing the composition. |
| Conductivity | a measure of a solution's ability to conduct electricity. |
| Extrinsic Property | s not essential or inherent to the subject that is being characterized. |
| Intrinsic Property | those that do not depend on the amount of substance present |

| States of Matter | defined as one of the ways in which matter can interact with itself to form a homogeneous phase. |
| Liquid | The particles in a liquid are free to flow. So, it has a definite volume, but not a definite shape. |
| Density | the relationship between the mass of the substance and how much space it takes up |
| Volume | a physical quantity that measures the amount of three-dimensional space occupied by matter |
| Molecules | group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided |
| Filtration | solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through |
| Chemical Property | a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed. |
| Chemical Change | one chemical substance is transformed into one or more different substances, such as when iron becomes rust. |
| Solubility | the ability to be dissolved, especially in water. |
