1. Length What is it? Distance from one point to another Unit(s) of measurement Meter (m) - basic unit cm smaller things mm km - bigger things Tools Metric Ruler Broken up into cm mm Example: your height

2. Mass What is it? The amount of matter in an object *Mass does NOT change due to location* Units of measurement Grams g - basic unit kg - bigger than gram mg - smaller than gram Tools Triple Beam Balance Example: Dog Apple

3. Volume What is it? Units of measurement Tool(s) Example: Amount of space an object takes up Liter - basic unit mL - smaller cm 3 1 mL = 1 cm 3 Regular objects - metric ruler ·L x W x H Irregular objects - graduated cylinder ·water displacement Water Block of wood Balloon

4. Density What is it? Unit(s) of measurement Tool(s) Example: The amount of mass in a given volume (mass per unit volume) mass/ volume = volume mass g/mL or g/cm 3 Mu st have both a mass unit And a volume unit Triple beam balance (to find mass) Ruler or graduated cylinder (to find volume) Rock
