Video Clip : Measuring Volume of Liquid

VOLUME OF LIQUID


Volume (also called capacity) is a quantification of how much space an object occupies.  The  volume of a solid object is a numerical value given to describe the three-dimensional concept of how much space it occupies.  One-dimensional objects(such as lines) and two-dimensional objects(such as squares) are assigned zero volume in three-dimensional space. 
            Capacity and volume can be distinguished; capacity being used for how much a container can hold(with contents measured commonly in litres or its derive units), volume for how much space an object displaces(commonly measured in cubic meters or its derived units)
MISCONCEPTION ON CAPACITY
            Many children come to school with some concept of length and some vocabulary associated with it.  And not much knowledge about capacity.  Perceptual comparisons  can be made between two containers, young children often make comparison on  length (to be exact, the height) rather than on capacity.  When asked which holds more, the tall container or a short container , most children will choose the taller container even if the shorter one actually holds more.  It is best to use direct comparisons.
            One of  the measurable attribute in KBSR mathematics Year 2 is the measurement of volume  of  liquid. A systematic conceptual development will indeed help student learn the topic on liquid measurement more effectively.  Based on the measuring process, the following are suggested as pedagogical development for the topic volume of liquid in Year 2:

  •   Identifying the attribute for the volume of liquid
  •   Direct comparisons of volumes of liquid
  •   Indirect comparisons of volumes of liquid through a reference
  •   Identifying instruments used as non-standard measurements for volumes of liquid
  •   Measuring volumes of liquid using non-standard measurements
  •   Introducing standard measurements for volumes of liquid
  •   Measuring volumes of  liquid using standard measurements in litres(l).

LEARNING ACTIVITIES 1 (LOWER LEVEL)


Learning Outcomes:
  • Compare the volumes of two liquid by direct comparison
Materials:
1  Tall Jar   (filled with orange juice)
1  Short Jar (filled with orange juice)
2  Mineral water bottles (empty)
Procedures: 
 1     Teacher put on the table 2 different size of jars with orange juice and ask the pupils  to see.
Example:
 
 
2     Then ask them which of  the container has more juice. Container A or container B.
3      Teacher put 2 empty mineral water bottles beside the Container A and container B. 
4      Pupils will be asked to come out in pairs and pour the juice into the mineral water bottle. Then they have to compare and note down which container holds more water.

5     The activity will be carry on till all the pupils get the opportunity.
6      At last,  pupil tells which jar holds more juice.

7      Teacher make the conclusion by asking students few questions as below:
i.    Which jar looks big?
ii.   Does taller jar holds more juice?

8     Teacher explain to the pupil that capacity of different size of the container gave different reading.                                                                              

LEARNING ACTIVITIES 1 (HIGHER LEVEL)


Learning Outcomes: 
         * Measure and compare volumes of liquid using standard unit.
    Materials:
    1  Tall Jar   (filled with orange juice)
    1  Short Jar (filled with orange juice)
    2  Cylinders

    Procedures:
    1      Teacher put 2 different size of jars with  orange juice on the table and place the table in the middle of the classroom.

    2      Pupils will be asked to stand in a circle and observe the jar.  Teacher will place 2 cylinders beside the jars.

    3      Pupils will be asked to come forward in pairs , pour the juice inside the cylinders the they will write down the  measurement in unit(l).
    4      Each pupil must know the measurement of  the jar A and jar B.
    5      Once all the pupils finished the activity , teacher ask them to tell which jar holds more and which jar holds little.

    6     Teacher make the conclusion by asking students few questions as below:
    i.     Which jar looks big?
    ii.    Does taller jar holds more juice than the shorter jar?
    7      Teacher prepared similar activities as station games. Provide worksheet to pupils.
    8      Pupils need go to each station and measure the liquid and compare the measurement and write it in the worksheet.

    LEARNING ACTIVITIES 2 ( LOWER LEVEL )


    Learning Outcomes:
    Measure and compare volume of liquid using non-standard measurements.
    Materials:
          (5  Different shapes  of  bottles with similar size)
    1  Jam bottle (filled with rose juice)
    1  Mineral water cup (filled with rose juice)
    1  Hand wash bottle (filled with rose juice)
    1  Perfume bottle (filled with rose juice)
    1  Juice bottle (filled with rose juice)
    5  Glasses (standard size)

    Procedures:
    1.      This activity will be carried out in groups where each table of 6 pupils. Place 5 different shapes of  bottles on each table and all the bottles filled with the same level of rose juice and labelled .
    2.      Each pupil will be given a piece of paper with the drawing of the bottles. They have to estimate the capacity of the 5 bottles in ascending order.
    3.      Teacher will place same shape and size of   5 glasses on each table.
    4.      Pupils need to pour the rose juice in each glass.
    5.      Then they have to look at the level of the rose juice.

    6.      Pupils write down the level according to sequence. And compare with the estimation that they made earlier.
    7.    Teacher makes the conclusion by saying that, even though the level of the rose juice is the same but the shapes of the bottles will not give the same measurement.
