Measuring of liquid is a identifying the attribute for volume of liquid. Volume of liquid is a mathematical skill that is taught in our primary schools. The volume of a liquid is the volume of the portion of a hollow container occupied by the liquid. Basically, we use measuring in every day applications. Liquids have no definite shape. Measuring of liquid has many practical applications in real life situations.
A beaker can be used to know the volume of an available liquid. As mentioned earlier, the liquid volume is directly proportional to the height of its container of uniform cross section. Therefore, in a graduated beaker, the readings are calibrated to directly give the value of the volume.
The volume of liquid is defined as the amount of space the liquid occupies. Liquid and gases are shapeless, so they occupy the space available in the containers they are filled. The capacity of the container is deferred as the maximum liquid volume that can be filled.
Measuring volume of liquid can teach students understand that containers that look taller do not necessarily hold more liquid, because volume is determined by both the height and the base measurements Misconception on capacity may arise among the students while teaching volume of liquid, especially when comparing capacity of two containers that can hold more.
Students often make the comparison on the height rather than its capacity. The students also will learn to read the meniscus on a graduated cylinder correctly. The students will measure and combine liquids to receive the expected results.

2.0 VIDEO CLIP (MEASURE of VOLUME of LIQUID )
This video clip above shows one type of measure the volume of liquid by using a graduated cylinder. Volume is the amount of space a substance occupies. The graduated comes in different sizes. It is easy to read.

can pour from a bottle and jug into thecups.
Write it out, as per the format below:
3. Ask pupils to measure and compare volume of liquids in two different
containers.
4. Pupils pour water from the jug into bowls and measure how many bowls
can hold the water from jug.
5. Teacher will divide the class into 4 groups and get them work in their
cooperative groups. Appoint one of the pupils in the group to be the
recorder.
recorder.
6. Teacher will give one jug and one bottle with full water to all the groups.
7. Now the pupils in the groups will demonstrate and fill up the cups with the
given water, and which contains more volume of water. Have the pupils
record their findings in the following result card :
8. Low achiever pupils will demonstrate pouring water from jug into cups.
6 Divide the pupils into group of five to do work in their cooperative learning.
Each group will be given two 1 liter cylinders, Jug of water and a bowl of water.
Ask pupils to pour water from the Jug into the cylinder and measure the
volume of liquid. Pupils recorded the volume of water in the jug in liters.
7. Pupils repeat with other items such as bowl of water and a bottle of
water pour into cylinders and beakers. Pupils measure the volume of
water in the bowls using standard units.

Topic : Volume of Liquid
Learning area : Measuring and Comparing Volume of Liquids
Learning area : Measuring and Comparing Volume of Liquids
Learning Objectives : Measure and compare volumes of liquids using Standard Unit.
Learning Outcomes : Measure and compare volumes of liquids using standard unit.
Materials:
Ø 1000ml Cylinders
Ø 1000ml beakers
Ø Bowls
Ø Jug of water
Ø Bottles
Procedures:
1. Teacher shows a bottle of full water to pupils. Ask pupils the accurate volume
of water in the bottle.
2. Teacher emphasise the volume of liquid is measuring water.
3. Teacher introduces the cylinder which measures volume of liquid accurately
to pupils. Ask pupils to read numbers on the side that can help pupils
to determine the volume in millilitres (ml).
4. Ask pupils to read the the bottom of the meniscus is taken as the liquid level
in the cylinder.
5. Teacher draws a picture of cylinder with measuring number on side.
Emphasise measuring volume of liquids by using standard units. (e.g. 1000ml = 1 liter)
1000 ml = 1 litre 1. Teacher shows a bottle of full water to pupils. Ask pupils the accurate volume
of water in the bottle.

5.0 Conclusion
For this activities pupils know that volume of liquid can be measured by using metric units such millilitres and liter. They also understand the relationship between both measurement tools. Measuring liquid volume is a fundamental and frequently encountered lab task. However, liquid volume is frequently measured using either a graduated cylinder.
For this activities pupils know that volume of liquid can be measured by using metric units such millilitres and liter. They also understand the relationship between both measurement tools. Measuring liquid volume is a fundamental and frequently encountered lab task. However, liquid volume is frequently measured using either a graduated cylinder.
Learning volume of liquid is a systematic conceptual development will help pupils on liquid measurement more effectively. In these activities pupils will direct comparisons of volume of liquid and identifying instrument used as non-standard measurement for volumes of liquid.
Exploration of capacity or volume of liquid involves manipulation of containers of various sizes that may either be collected or purchased for classroom activities. Pupils collect some containers such as mineral water bottles, soft drink cans, vases etc which can be found around them. This will help them to know better in contextual learning. Pupils also will learn to read the meniscus on a graduated cylinder correctly.
