||Title: MEASUREMENT
Background: The meter is the standard unit of measure in the metric system. The meter stick is 1 meter long. A meter is composed of 100 centimeters. A meter is composed of 1000 millimeters. A meter is composed of 10 decimeters.
To convert meters to decimeters multiply by 10
To convert meters to centimeters: multiply by 100
To convert meters to millimeters: multiply by 1000
To convert dm to m: divide by 10
To convert cm to m: divide by 100
To convert mm to m: divide by 1000
To convert cm to mm multiply by 10, to convert mm to cm divide by 10.
Question #1: Often in Science, we use either a metric ruler or a meter stick in the lab. What is the difference?
Materials: meter stick, metric ruler,
Procedure:
Measure the various objects listed in Table 1 to the nearest unit indicated:
L and W of Classroom & Door: nearest cm -- Finger: nearest mm -- desk: 0.1cm
After you have completed all of your measurements, then convert all of your measurements into m, dm, and mm as listed in your tables.
Observation:
Table 1:
mmcmdmmLength of Classroom *Width of Classroom * *Length of your shortest fingerGreatest Height of your desk-topLongest Side of your desk-topHeight of class doorWidth of Class door
* Length of CR = from WB to yellow wall
** Width CR = from Side Cabinet to bulletin-board wall
Analysis: (skip)
Conclusions:
Which apparatus of metric measure (the meter stick of the metric ruler) is more useful in measuring the length and width of your classroom. Explain.
Which unit of metric measure (m, dm, cm, mm) is more useful in measuring the thickness of a quarter.
How many mm are there in 1 meter?
How many cm are there in 1 meter?
How do you convert cm to m?
How do you convert m to cm?
What is easier, converting m to cm; or converting yards to inches. EXPLAIN.
If you measured the length of an object to the nearest 0.1 of a centimeter, and your partner measured the same object to the nearest centimeter, who would have the more accurate measurement? EXPLAIN
