YOU ARE NOT THE ONLY ONE TO CREATE A METRIC CARTOON–

TYPES OF MEASUREMENTS Length – Distance between two points Volume – The amount of space occupied by an object Mass – The amount of matter (“stuff”) in an object Temperature – A measurement of the average amount of kinetic energy (energy of motion) of the particles in an object

BASE UNITS Length – meters or m Volume – � Liquid or Irregular shaped object – milliliters or m. L � Regular shaped object - centimeter cubed or cm 3 1 cm 3 = 1 m. L Mass – gram or g Time – second or s Temperature – celcius or °C � Temperature °K can also be measured in Kelvin or

MEASURING TOOLS Length – Centimeter Ruler, Meter Stick Volume – � Liquid – graduated cylinder � Irregular shaped object – graduated cylinder � Cube, rectangular prism, triangular prism, etc – centimeter ruler Mass – Triple Beam Balance, Electronic Balance, Double Pan Balance Time – Clock Temperature – Thermometer (manual or digital), sensor or probe
