Solid | Particles are packed tightly together and it has a fixed shape. |
Liquid | Particles are flowing. Has a fixed volume. Takes the shape of the container. |

Density | The amount of matter packed into a given volume of a substance. Observed by Sinking or Floating. |
Magnetism | The pulling force of a magnet. |
Properties | Characteristics that describe objects including color, shape, size, texture, smell, taste, luster, magnetism, density, length, state of matter, flexibility, volume, mass, conductivity. |
Conductor | An object that allows electricity or heat to pass through easily. |
Insulator | An object that stops or slows down the flow of electricity or heat. |
Physical State | The states of matter. Solid, liquid,and gas. |
Buoyancy | An upward force. The ability to float. |
Classify | To sort objects into groups that are alike in some way. |
Soluble | The ability to be dissolved in or by a liquid. |
Electric energy | The form of energy that consists of a flow of electric charges through a conductor. |
Thermal energy (heat energy) | The energy of moving particles that produces heat. |
Weight | Measured by how much gravity pulls an object down. |
