| matter | the "stuff" that makes up everything in the universe (except energy) |
| mass | the amount of matter in an object |
| weight | the amount of gravitational pull on an object |
| volume | the amount of space an object takes up (size) |
| density | the amount of mass in a given volume |
| gravitational pull | the force of attraction ALL objects have on all other objects |
| triple beam balance | TOOL to measure mass |
| grams | UNIT of measurement for mass |
| Does mass change? | NO- only if you add or take away matter |
| increased mass = _____ gravitational pull | increased gravitational pull |
| Does weight change? | YES- depending on the pull of gravity |
| Weight on Mt. Everest | Weight here decreases- further from center of gravity |
| Weight in Mariana Trench | Weight here increases-closer to center of gravity |
| Weight on Pluto | Weight here decreases- planet has less mass=less gravitational pull |
| Weight on Jupiter | Weight here increases-planet has more mass=more gravitational pull |
| ruler | TOOL of measurement for volume of regular solids |
| cm3 | UNIT of measurement for volume of regular solids |
| graduated cylinder | TOOL of measurement for volume of liquids |
| mL | UNIT of measurement for volume of liquids |
| water displacement | method of finding volume of irregular solids by dropping them into water to measure the change in volume |
| L x W x H | FORMULA for volume of regular solids |
| Mass / Volume | FORMULA for density |
| g/cm3 | UNIT of measurement for density |
| density of water | 1 g/cm3 |
| When does an object sink in water? | if the object is denser than water |
| When does an object float in water | if the object is less dense than water |
