  • 8. Metric Unit Abbreviation What does it measure Equipment used 1. Meters - m Length – distance from one area to another Ruler, meter stick, tape measure 2. Grams g Mass – amount of matter an object has Triple beam balance
  • 9. • How much matter does 1 gram have? Eraser on a pencil Small paper clip
  • 10. SAYING MASS IS EASY... Simply Lose Weight! • What is the difference between mass and weight? Mass measures matter and the amount of matter you have doesn’t depend on gravity. Weight is a measurement of gravitational pull. You weigh less at the equator because you are far away from the magnetic poles!
  • 11. Metric Unit Abbreviation What does it measure Equipment used 1. Meters - m Length – distance from one area to another Ruler, meter stick, tape measure 2. Grams g Mass – amount of matter an object has Triple beam balance 3. Liters l Volume – amount of space in a liquid Graduated cylinder
  • 12. Metric Unit Abbreviation What does it measure Equipment used 4. Celsius c Temperature – how much heat something has thermometer • 0 degrees is freezing • 100 degrees is boiling
  • 13. Here is a rhyme to help you with some reference points for Celcius… • 30 is warm, 20 is nice, 10 is cold, and 0 is ice! • A hot day is about 30° Celsius. • Butter melts at 31 degrees Celcius. • • Hot Coffee is about 75 degrees Celcius
  • 14. The Metric System is made up of 6 prefixes. Each prefix has a numerical value. Prefix Kilo Number value 1000 Hecto Deci Centi Milli k 100 h 10 Deca Basic unit Symbol da 1 m, l, g .10 or 1/10 .01 or 1/100 .001 or 1/1000 d c m To help us remember the order
