The Metric System • Why do we use it? • It was created in the 1700’s to give scientists a universal system of measurement that everyone could understand. • Most other countries in the world use metric measurements in their everyday lives
How does it work? Three common base units of measurement are:
Length To measure length, we use a meter stick
Mass To measure mass, we use a triple-beam balance or scale
Liquid Volume To measure liquidvolume, we use a beakeror a graduated cylinder
Solid Volume • To measure solidvolume, use one of two methods: • Displacement • Formula • Common unit: • Cubic centimeter (cm3) • 1 cm3=1mL
The Metric System – Practice Identify which unit best matches the measurement described: • The mass of a package of gum • The width of a laptop screen • The liquid volume of a soda bottle • The diameter of a pencil • The solid volume of an orange
