| Weight | Measures the pull of gravity on an object. It changes in different places. |
| Mass | The amount of matter in an object. It does not change in different places. |
| Volume | How much space matter takes up. |
| Milliliter | A unit to measure the volume of a liquid. |
| Cubic Centimeter | A unit to measure the volume of a solid. |
| Gram | A unit to measure an objects mass. |
| Density | Relates the mass of an object to its volume. |
| Triple Beam Balance | A balance that is used to measure the mass of an object. |
| Matter | Anything that has mass and takes up space |
| Molecule | When two or more atoms are bonded together |
| Solution | A mixture where substances are evenly distributed. When substances dissolve. |
| Chemistry | The study of properties of matter and how matter changes. |
| Element | A kind of matter that cannot be broken down into any other substances. |
| Mixture | When two or more substances are mixed together but not chemically combined. The parts can be easily separated |
| Atom | A basic particle from which all substances are made. |
| Heterogeneous Mixture | A mixture where substances are unevenly distributed. |
| Compound | A particle that is made of two or more substances that are bonded together. |
| Chemical bond | A pulling force that holds two atoms together. |
| Homogeneous Mixture | A mixture where substances are evenly distributed. |
| Chemical Property | Tells how matter can change into new kinds of matter |
| Physical Property | How matter looks, smells, sounds, and tastes. |
| Substance | A single kind of matter that is pure. |
| Chemical change | When matter changes into a new kind of matter and the new matter has different properties from the original matter. |
| Physical change | When the way that matter looks changes. It does not change the matter into a new kind of matter. |
| separating using magnetism | When you use a magnet to separate matter, such as separating iron filings from sand. |
| separating using filtration | When you use filter paper to separate matter, such as separating sand from salt water. |
| separating using evaporation | When you boil a liquid using a hot plate to separate matter, such separating the salt from salt water. |
| separating by hand | When you use tools like tweezers or your hands to physically separate matter, such as separating peppercorns from sand. |
