MEASURING OBJECTS

Characteristic to Measure MEASUREMENT Characteristic to Measure Definition Measuring Device Units

MEASURING LENGTH Distance between two points Use a ruler or meter stick Units are in meters (m), centimeters (cm), or millimeters (mm)

MEASURING MASS The amount of matter in an object Use a/an (electronic) balance Units are in grams (g)

MEASURING VOLUME The amount of space an object takes up Graduated cylinder Units are in cubic centimeters (cm3) or milliliters (ml) calculate – for regular shaped objects water displacement method – for irregular objects

MEASURING TEMPERATURE Measure of hotness or coldness of an object Use a thermometer Units are in degrees Celsius  0 °C = freezing point of water  100 °C = boiling point of water
