Measure and Compare Volume of Liquid

a. The Meaning of Volume of Liquid

Volume of liquid refers to the capacity of liquids in the containers. Capacity can be measured by using non standard units (more or less) and in standard units. The metric system used is millimeter (ml) and litter (l). An  investigation amount of liquids can be  done by pouring liquids between containers using different shapes and sizes. This  exploration of capacity or volume of liquid involves manipulation of containers in various sizes. Pupils can  either collect or  purchase them for classroom activities. A cheap way to do the activities is sure to collect some containers like mineral water bottles, soft drink cans, and vases.  They are all can be found around them.

After the activity, teacher can display those collections of containers at the learning points for students to explore  more. It is hoped that students can  apply standard unit in liters and millimeters in everyday  activities. 


b. Teaching and Learning Activities

How to Measure and Compare Volume of Liquid

Activity 1; Using non-standard units

Learning Outcomes;

By the end of the lesson, pupils will be able to measure and compare volume of liquids by using non-standard units correctly.

Prior Knowledge;

Pupils had learnt how to compare objects: more or less, many or a few, high or low during their previous lesson while learning :Whole Numbers'.

Teaching Aids;

Different sizes of containers, a pail of water,

Vocabulary;

more, less, empty, half full, and full.

Procedures;

1. Divide the pupils into group of four to do work in  cooperative learning.

2. Appoint one student to note every point.

3. Give each group 5 set of containers with different sizes, a pail of water, and a small cup as the measurement tool.

4. Each group will record the numbers of cup needed before fill them with water.

5. Record them into the form given.

* Also teach the pupils to do estimation such as half full, full, and empty.


Conclusion;

For this activities pupils will bear in mind that the volume of liquid will be determined based on the containers used. The more bigger containers the more quantities of water is needed to fill in.

Activity 2; Using standard units

Learning Outcomes;

By the end of the lesson, pupils will be able to measure volume of liquids by using standard units correctly.

Prior Knowledge;

Pupils had learnt that the content of water will be determined based on their containers. The bigger containers show more volume of liquid while the smaller containers give us less volume of liquid.

Teaching Aids;

Different sizes of containers, a pail of water,

Vocabulary;

more, less, empty, half full, full,

Procedures;

1. Divide the pupils into group of four to do work in their cooperative learning.

2. Appoint one student to be the recorder in the group

3. Give each group 5 set of containers of different sizes, a pail of water and two measuring cylinders. ( One   
    for milliliter and another one for liter)

4. Each group will fill every container with water.

5. They will measure the volume of liquid in each container by pouring the water from the containers into the measuring cylinders.

6. A group member record the results in the form given

*• Introduce the pupils that 1 liter = 1000 milliliter

• 1 liter x 1000 milliliter = 1000 milliliter

Conclusion;

For this activities pupils know that volume of liquid can be measured by using metric units such milliliters and liter. They also understanding the relationship between both measurement tools.

Activity 3: Using non-standard units and standard units

Learning Outcomes;


By the end of the lesson, pupils will be able to measure and compare volume of liquids by using standard units and non-standard units correctly.

Prior Knowledge;

Pupils had learnt how to measure volume of liquid using non-standard units and standard units.

Teaching Aids;

Different sizes of containers, 2 measuring cylinders, a pail of water,

Vocabulary;

more, less, empty, half full, full,

Procedures;

1. Divide the pupils into group of four to do work in their cooperative learning.

2. Appoint one student to be the recorder in the group

3. Give each group 3 set of containers of different sizes, a pail of water and two measuring cylinders. ( One for milliliter and another one for liter)

4. Each group will fill every container with water and state which is more or less.

5. Then, they will measure the volume of liquid in each container in liter and milliliter by pouring the water from the containers into those measuring cylinders.

6. A group member record the results in the form given



Conclusion;

For this activity pupils know that volume of liquid can be measured by using non-standard units, but the results just under estimation. By using metric units such milliliters and liter we can find more accurate with the results. On the other hand, pupils also able to understand the relationship between both measurement tools.


Game 1;
1. Play the game in group of 5 students
2. Appoint a student in the class to be the recorder.
3. Appoint the student to be the shuffled of the cards
4. The game consists 5 rounds to finish
5. It begins, when the group members will be given a face down card on the table in every round.
6. Then, they open up the cards and read the volume of liquid stated on. The student with the biggest amount
    is the winner in that round.
7. Repeat until 5 rounds.
8. The group with the highest marks is the winner.







Game 2;
1. Play the game in group of 5 students
2. The 4 colors on the spinning board refer to every group.
3. Each member o the group will spin “The Spinning Board”
4. When it stops and the arrow point out to one of the color. He/she will take out one card from the “Magic
   Container” and read the volume of liquid stated.
5. If the arrow point out to the white color, the pupils lost the game and continue to other groups,
6. The volume of liquid will be recorded until round of 5
7. The group with the highest marks is the winner.


Summary

The learning of volume of liquid begins with concrete experience in realistic situations through measuring using both standard and non-standard units. The capacity of liquid in standard units are measured in millimitres(ml) and litres(l) in the metric system. While in non-standard units they are measured using various containers by stated the capacity wheather more or less. Materials from non-standard units are easier to obtain. It is good to give children experience with unfamiliar systems of measurement .
