| Weight | The amount that gravity pulls on a certain mass measured in pounds and ounces. |
| Liquid | Takes the shape of it's container ( Atoms are packed together loosely) |
| Gas | Only takes the shape of a container if it trapped in (atoms are very free,constantly moving) |
| Solid | Has it's own shape,can change. |
| Volume | The amount of space an object takes up (measured in cubic centimeters =cm 3 |
| Water Displacement | A method of measuring the volume of an irregularly solid shape. |
| Buoyancy | If it is in the shape of a ball in sinks If it is spread out it floats. |
| Negative sink | Is displaced in water. |
| Positive float | That water pushes up. |
| Neutral | Stay where it's at. |
| Density | A measure of how tightly packed the atoms of substance are. |
| Density of water = 1 | if the density of an object is more then one it sinks, if the density of an object is less then one it floats. |
