| A | B |
| volume | the amount of space an object takes up |
| matter | anything that takes up space and has mass |
| mass | the amount of matter in an object (measured in grams & kilograms) |
| solid | matter that has size and volume but no shape |
| liquid | matter that has definite size and volume but no shape, molecules are spaced apart and flow against each other |
| gas | matter that has no size, shape or volume. the molecules are spaced far apart and bounce off each other |
| atoms | the smallest particle of matter. these form molecules |
| physical change | changes size, shape or state but stays the same matter |
| solids that dissolve in water | salt, sugar and kool aid |
| solids that DO NOT dissolve in water | sand & clay |
| heat helps things | dissolve faster |
| matter is made of parts | too small to be seen without magnification |
| magnification is when u | make something bigger so u can see smaller parts |
| physical properties (size, shape, and state) | stay the same even when matter is reduced in size |
| physical change of melting ice | changes state |
| phyical change of cutting bread | change size |
| physical change of rolling playdoh | changes shape |
