The metricsystem

  1. 1.   Must have a standard.  A standard is an exact quantity people agree to use for comparison.  A standard means two people using the same object should get close to the same results. Measurement
  2. 2. Standards of the past  People used to use parts of their body to determine the length of something.  The standard would be a part of the king’s anatomy.  The standard yard was the distance from the king’s nose to his outstretched arm
  3. 3. People would use their feet to measure distance  This is how the term foot came about.  Today the standard “foot” in the English system is  12 inches = 1 foot
  4. 4. The English system is very confusing because it has so many different values
  5. 5.  America is the only country that still uses the old English system
  6. 6.  Scientists give the English system the thumbs down Scientists needed an exact and uniform system of weights and measurements
  7. 7.  How did the metric system come about?  During the18th century scientists measured the distance from the earth’s equator to its North Pole and divided it into ten million parts.  This is how they came up with the length of the standard meter.
  8. 8.  The Meter  The standard for the meter is kept in a safe in France.  The meter stick is a replica of that standard  A meter is made up of 100 centimeters and 1000 millimeters
  9. 9.   Scientists needed a way to measure liquids so they took 10 cm and multiplied it by its length x width x height to come up with a standard for measuring volume  The liter is the size of 10 cm(3)  10cm x 10 cm x 10 cm  Length x Width x Height = Volume  The liter is used to measure liquids How the liter came about
  10. 10.  How the Gram came about  Scientists needed a standard to measure mass.  Mass is the amount of matter in an object  They decided to take one cubic centimeter of water and call it a gram
  11. 11. The time standard  During the 15th century a scientist named Galileo set the standard of time known as the second
  12. 12.  The Mistake Two different groups of scientists were working on the calculations to send a probe to Mars. The American team did their calculations in the English standard and the other team did it in the metric system (OOPS!)  MARS
  13. 13.   This made scientists very upset.
  14. 14.   Kilo  means thousand (1000)  Hecto means hundred (100)  Deca means ten (10)  Deci means one-tenth (1/10)  Centi means one-hundredth (1/100)  Milli means one-thousandth (1/1000) Metric chart
  15. 15.   The Meter- Measures length  Length is the distance between two points  The Liter –Measures Volume  Volume is how much space a liquid takes up  The Gram- Measures mass  Mass is how much matter is in an object Copy This Down
  16. 16.   How to use the metric chart  Rewrite the problem  Check for the decimal (if no decimal, put at end)  Where do we start? Put pencil their  Were do we go to?  # of hopes and direction  Do the same with decimals Metric chart
  17. 17.  kilo  hecto  deca     UNIT    deci  centi  milli    (meter, gram or liter)    How the metric system works •100cm = ___ m100cm = ___ m •100cm = 1.0 m100cm = 1.0 m •6.9mm = ___cm6.9mm = ___cm •6.9mm = .69 cm6.9mm = .69 cm
