  1. MEASUREMENT

  2. Measure • We measure in order to 1.) DESCRIBE 2.) COMPARE • We measure: (1.) Length (2.) Mass (3.) Volume • In Science we measure using the METRIC SYSTEM. It is based on the number 10. LENGTH – The Basic Unit is METERS MASS – The Basic Unit is GRAMS VOLUME – The Basic Unit is LITERS

  3. To change the Basic Unit we add a prefix to the base word. • Kilo = 1000 Deci = 1/10 Centi = 1/100 Milli = 1/1000 • Example: Kilometer 1,000 meters • ONE METER = 10 decimeters 100 centimeters 1000 millimeters

  4. VOLUME • Volume is how much space something takes up. • The unit volume is measured in LITERS (L) or CUBIC CENTIMETERS (cm3) • There are two ways to find volume

  5. Regular Objects • 1. To measure a regular object (regular – it can be measured with a ruler) • LENGTH x WIDTH x HEIGHT

  6. IRREGULAR OBJECTS • 2. To measure an irregular shaped object (Irregular – it can not be measured with a ruler) • Use the WATER DISPLACEMENT METHOD • The instrument used to measure the volume is a Graduated Cylinder • The Meniscus is the curved (concave) line in the graduated cylinder at the top of liquid.

  7. Meniscus Reading
