MEASUREMENT WEEK 10 Measurement
Definition of Terms Measurement is an integral part of science. It consists of
a number and a unit.
Time
Measuring length
Time is the on-going sequence of events taking
place. The past, present, and future. Length is the size of a straight line, distance, or

Reading an Analog clock: MEASURE OF WEIGHT
1 gram (g) = 1000 milligrams (mg)
The big hand tells us the minute.
The small hand tells us the hour. 1 kilogram (kg) = 1000 grams
The long hand tells us the second.
LIQUID MEASURES
1 liter (L) = 1000 milliliters (mL)
1 deciliter = 1/10 liter
Volume and Capacity Units
Volume- is how much space an object takes up, for both
solid objects (no empty spaces) and with empty spaces.
Capacity- is how much you can fill a space with for

Another way to measure volume is to find out
how many cubes of the same size you can fit in
to the object.
To measure the capacity or volume of an object
is to find out how much liquid you can fill it
with.
Measurement using Non-Standard Units
1. Direct comparison of liquid volumes
To directly compare the capacity of two containers is to
fill up one container and transfer that amount of water in
to the other.
If it overflows, the first container is bigger, or is able to
hold more water. If all of the water from the first
container can be poured into the second container
without completely filling it, then the second container
holds more water.
2. Indirect comparison of liquid volumes
To indirectly compare the capacities of two containers is
to fill up both containers and pour their content in to two
identical containers. By looking at the height of the
liquid in the two containers, we can decide which
container had more liquid.
Measurement using Standard Units
Student’s measurement experiences must enable
them to:
1. Develop an understanding of the size of a Liter and 10
milliliters. (1milliliter is too small to be appreciated);
2. Estimate and measure using liters and milliliters;
3. Develop an understanding of the size of a cubic meter
and a cubic centimeter;
4. Estimate and measure using cubic meters and cubic
centimeters.
