  1. The Metric System

  2. What is the Metric System? • The metric system is a system of measurement that is based on the number ten • It is often used in science and in countries around the world

  3. How is it different? • The metric system uses meters, grams, liters and Celsius • The English System uses feet, ounces, gallons and Fahrenheit

  4. What can be measured? • The metric system can be used to measure mass, volume, length, and temperature

  5. What is mass? • Mass is the amount of matter in an object

  6. What is volume? • Volume is the amount of space an object occupies

  7. What is length? • Length is the distance between two points

  8. What is temperature? • Temperature is the average motion of particles • We can relate this motion to how hot or cold it is.

  9. What is density? • Density is how much mass an object has in a given space. • The formula for density is: Density = _ Mass__ Volume

  10. How do we measure mass? • Mass is measured by using a balance • The metric units for mass are the gram (g), and kilogram (kg)

  11. What is weight? • Weight is the amount of gravity that acts upon an object

  12. Are mass and weight the same? • Mass and weight are different. • Mass is the amount of matter in an object and weight is determined by the amount of gravity and matter in an object. • This is why your weight changes on different planets

  13. How do we measure length? • Length is measured using a ruler • The metric units for length are the meter (m), centimeter (cm), and the millimeter (mm)

  14. How do we measure volume? • We use a graduated cylinder for liquids • We use a ruler for rectangular solids (L x W x H) • We use the water displacement method to determine the volume of irregularly shaped objects • The metric units for volume are the liter (L), the cubic centimeter (cm³), and the milliliter (mL)

  15. How do we measure temperature? • Temperature is measured using a thermometer • The metric unit for temperature is Celsius (°C)
