3. Each group will elect or choose a student to record the amount of liquid collected by each group using the given worksheet.
4. Each member o the group will spin “The Spinning Board” and when it stops and the arrow point out to one of the colour. A member of the group will take out one card   and read out loud the volume of liquid stated. 
5. If the arrow point out to the black colour, the group will lost its turn and the turn will be given to the other groups. 
6. The volume of liquid will be recorded until round of 5
7. The group with the highest total units obtained will be declared the winner.

Concept of Full, Half Full and Empty

The amount of space the liquid occupies, simplify the definition of volume of liquid.

Glass of Water - Empty,  half full and full


The teacher will arrange three glasses and fill two glasses with half full and the other full of water.

The students will be given a brief explaination of the concept of :

(a) Full - means the liquid occupies all the space of the container
(b) Half - means the liquid occupies half of the space of the container
(c) Empty - means there is no liquid in the container

This exercise can be simulated using other containers which can be available in school such as the following :


Disposable Cup

Water conteiners 5 litres

Paper Cup


Mineral Water Plastic Bottle
School Tumbler


Vocabulary :
i. Full
ii.Half
iii. Empty
iv. More than
v. Less than

Unit of Measurement

Now, let's learn on What is the unit for measurement of volume of liquid

The standard measurement using metrix measurement system for volume or the amount of liquid are litre and militres

1 litre ( l) is equivalent to 1000 mililitres (ml)

Conversion of Units

First,  the teacher should explain to students that the larger units between litres and mililitres is litres. In order to convert the unit of measurement from a larger (litre) unit to the smaller ones (mililitres), the students MUST multiply the unit given in litre or litres by 1000 and vice versa.




Conversion from Litre to Mililitre
Example 1 : Calculate the unit in mililitres if the unit given in litre is 2 litres.

Remember that the given units in litre must be multiplied by 1000 then we get => 2 litres x 1000 = 2000 mililitres

Conversion from mililitres to litre
Example 2 :Calculate the unit in litre for 3000 mililitres

In this case, the question requires to convert a smaller measurement unit to a larger ones then we divide the unit with 1000 then we get => 3500 / 1000 = 3.0 litres


Note : Teacher should explain the concept of large and small units through the simple ways of how to differentiate which term refers to large unit and which term refers to a smaller unit of measurements. This learning concept can assist the students by inference using the word "mili" means small, tiny for mililitre and "large" connotes to litre.

Volume of Liquid : Which Container has more volume?

The confusion in determining which containers hold more volume of liquid amongst the students are based of their own observation if we are using non-standard containers.

For example, which container hold more volume of liquid based on the illustrated figure below:


Which one holds more volume right or left container?

Usually, students will pick the larger container as they perceived the larger container holds more liquid than the smaller ones. It is correct if the amount of liquid occupies the whole container. But, if the volume of liquid  only occupies partly of the space it can only be determined through two methods:


(a) Uniform Non-Standard Measurement 


This exercise can be simply measured by paper cups or other available materials to determine which containers holds more liquid.




The students can measure the amount of volume by using how many paper cups in container A and B. The more number of cups will give the answer of which containers holds more volume of liquid.

100ml paper cup
100 ml paper cup















This simple activity is crucial to assist the students' confusion on which containers hold more amount of liquid.


Let's measure which container has more amount of liquid.


1. The students will be divided into 2 main groups of 5 students each and will be given a paper
    cups which can hold 100 mililitres of liquid (each full cup).


2. Group A will be given the task to measure the volume of container A on the left and the other
    group will be given the task to measure the container B.

3. Each group will elect or choose amongst themselves a student to record the finding using a work sheet.


4. Then the students will begin measuring the volume in the container A and B


5. At the end of this exercise the group leader will announce, how many paper cups for each 
    container. Based on the quantity of cups, the teacher will ask the students which container
    holds more liquid. 


                                                          A                               B    

 Container A  = 5 Paper cups or 500 mililitres
 Container B  = 8 paper cups or 800 mililitres

Therefore, container B hold more amount of liquids than container B.

(b) Using Standard Measurement

The experiment can be done using different method through using the standard measuring equipment to determine the amount of liquid for each container.

1.  The teacher will introduce the buret to the students and give brief examination's on the features of a buret and its functions.

2.  Each group will know experienced the fun of measuring using the standard equipments to 
     determine which container holds more liquid

3.  The students will pour the amount in container A and B into two different measuring 
     equipments to derive to their observation and conclusion


B= 800ml
Container A = 500 ml





Happy learning.... it is fun right!

Video on "How to measure volume of liquid?"


The video demonstrates on "How to measure Volume of Liquid" using standard measuring graduated measuring equipments.

Graduated Measuring Cylinder

Before the measurement be recorded, the graduated cylinder must be placed on a flat surfaced to avoid inaccurate reading  of the volume. The next step is to ensure the position of eyes in measuring the volume of liquid must be level to the measuring cylinder not above or below the level of liquid.



The right position is putting the cylinder on a flat surface

Position of eyes when taking the reading of liquid 










It is fun. Come on students, do enjoy your experiment because "Practice Makes Perfect". Ready for fun exercise go to exercise page.


Vocabulary

i. Graduated measurement cylinder
ii. Position of eyes - angle
iii. Correct
iv.Incorrect
v. Flat
vi. Surface

What is Volume of Liquid?



The volume of liquid can be defined as  the amount of liquid that occupies a space in a container or storage item.

Example :

The volume of strawberry juice in a glass or a cup of coffee.


A glass of Juice

A Cup of Coffee
Orange Juice


Vocabulary  :

i. Amount
ii.Occupy
iii.A Space
