Understanding Metric Measurements: Length, Volume, Mass, and Temperature Units

Explore the fundamentals of the metric system, covering essential units of measurement for length (meter), volume (liter), mass (kilogram), and temperature (Celsius). Learn about metric prefixes such as kilo-, hecto-, and milli-, which help express various scales within the metric system. Discover how to calculate area and volume, including examples of commonly used dimensions. Familiarize yourself with tools like the triple beam balance and graduated cylinder, and understand key concepts such as meniscus in volume measurement.

  1. METRIC MEASUREMENTS Left Image: http://webapps.lsa.umich.edu/physics/demolab/controls/imagedemosm.aspx?picid=1167Right

  2. METRIC PREFIXES • KILO- 1000 • HECTA – 100 • DECA - 10 • DECI - .1 ONE TENTH • CENTI - .01 ONE HUNDREDTH • MILLI - .001 ONE THOUSANDTH

  3. METRIC BASE UNITS • METER –BASE UNIT FOR LENGTH • LITER – BASE UNIT FOR VOLUME • CELSIUS – BASE UNIT FOR TEMPERATURE • KILOGRAM – BASE UNIT FOR MASS

  4. METER (m) 1 METER (m) = 100 CENTIMETERS (cm) 1 METER (m) = 1000 MILLIMETERS(mm) 1 CENTIMETER (cm) = 10 MILLIMETERS (mm) 1 KILOMETER (km) = 1000 METERS (m) Left Image: http://webapps.lsa.umich.edu/physics/demolab/controls/imagedemosm.aspx?picid=1167Right

  5. AREA = LENGTH X WIDTH 2 • FFFFFFFF 10 CM X 7 CM = 70 CM 7 CM 10 CM LENGTH = 10 CM WIDTH = 7 CM

  6. VOLUME OF A SOLID VOLUME = LENGTH X WIDTH X HEIGHT LENGTH = 8 CM WIDTH = 6 CM HEIGHT = 5 CM 5 CM 6 CM 8 CM 3 8 CM X 6 CM X 5 CM = 240 CM

  7. VOLUME IS THE AMOUNT OF SPACE AN OBJECT TAKES UP

  8. LITER (L) BASE UNIT FOR MEASURING LIQUID VOLUME 1 LITER (L) = 1000 MILLILITERS (ML)

  9. MENISCUS THE BOTTOM OF THE CURVE WHICH IS USED TO MEASURE VOLUME IN A GRADUATED CYLINDER Left Image: http://morrisonlabs.com/meniscus.htm Right Image: http://www.tea.state.tx.us/student.assessment/resources/online/2006/grade8/science/images/20graphicaa.gif

  10. CELSIUS THE METRIC BASE UNIT FOR MEASURING TEMPERATURE IS DEGREES CELSIUS o AT 0 C DEGREES CELSIUS WATER FREEZES o AT 100 C DEGREES CELSIUS WATER BOILS

  11. ANDERS CELSIUS LIVED FROM 1701 -1744. FROM SWEDEN HE WANTED A 100 DEGREE DIFFERENCE BETWEEN FREEZING AND BOILING WATER. Image from http://en.wikipedia.org/wiki/Anders_Celsius

  12. THERMOMETER AS THE LIQUID WARMS UP, IT TAKES UP MORE SPACE IN THE BULB

  13. MASS • THE AMOUNT OF MATTER IN AN OBJECT • KILOGRAM (kg) IS THE BASE UNIT OF MASS • 1 KILOGRAM (kg) = 1000 GRAMS (g) • 1 GRAM (g) = 1000 MILLIGRAMS (mg)

  14. TRIPLE BEAM BALANCE AFTER THE OBJECT IS PLACED ON THE SCALE, THE THREE WEIGHTS ARE MOVED UNTIL THE LINES ON THE BEAM AND SIDE LINE UP

  15. DETERMINE THE WEIGHT AFTER THE SCALE IS BALANCED, THE WEIGHTS ON THE THREE BEAMS ARE ADDED.
