3.2 Topic 2: Measure and Compare Volume of Liquid Using 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 .

Prior Knowledge:

Pupils had learnt that the content of water will be determined based on their containers.

Teaching aids:

Different sizes of containers (apple juice bottle, oil bottle, pail, teapot , jug), a pail of water, measuring cylinders

Vocabulary:

more, less, empty, half full, full, measuring cylinder

Teaching and learning activities:

1.Teacher demo the ways to measure volume of liquid using measuring cylinder. Teacher shows way to read

   and record measurement from measuring cylinders correctly.

2.Two basic rules have to be considered for taking a correct reading from a measuring cylinder:

a.Your eye should be in line with the lower level of the surface of the water (meniscus);

b.The measuring cylinder has to be placed on a level surface and not be tilted, as in the illustrated example!

3.Teacher guides pupils use measuring cylinder to measure the volumes of liquid. They read the scales to the

   nearest litre or mililitre

4.Teacher introduce the pupils that :

*  1 liter = 1000 milliliter
* 1 liter x 1000 milliliter = 1000 milliliter

5. Divide pupils in four groups. Each group has high achiever and low achiever pupils. Pupils do work in their

    cooperative learning.

6. Appoint one student as a group leader to record the group result in the table.

7. Give each group 4 set of containers of different sizes and shapes (apple juice bottle, oil bottle, teapot ,

    jug), a pail of water, measuring cylinders.

8. Each group will fill every container with water.They will measure the volume of liquid in each container by

    pouring the water from the containers into the measuring cylinders.

9. Pupils compare volume of liquid as below:

a. apple juice bottle and oil bottle

b. teapot and jug

10. A group leader will record the results in the table form given.

Containers	Volume of liquid ( litre)
a. Apple juice bottle
Oil bottle
b. Teapot
Jug

11. Pupils do exercises according for high achiever and low achiever pupils.

      Exercise 1: high achiever pupils

Exercise 2: low achiever pupils

Conclusion:
1.Volume of liquid can be measured by using measuring cylinder in units such milliliters and liter.

2.Pupils understanding the relationship between litre and mimilitre (1 liter = 1000 milliliter).
