1. MEASUREMENT

2. Measure  We measure in order to 1.) DESCRIBE 2.) COMPARE 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. 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 100 centimeters 1000 millimeters 1000 millimeters

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

5. Regular Objects  1. To measure a regular object (regular – it can be measured with a ruler) (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) (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.
