2.1 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 in millimeters (ml) and litters (l) in the metric system. Investigations amount of liquids which can be poured between containers of different shapes and sizes. Exploration of capacity or volume of liquid involves manipulation of containers of various sizes that may either be collected or purchased for classroom activities. A cheap way to do the activities is to have your students collect some containers such as mineral water bottles, soft drink cans, vases etc which can be found around them.Teacher can display those collections of containers in a learning centre for students to explore capacity measurement. Every learning centre should have at least a standard graduated measuring cylinder in liters and millimeters. This is to enable the students to measure volume of liquids especially in standard
units.
2.2 Measuring Cups
Liquids are measured using tools called measuring cups. Measuring cups help us to use the right amount of liquid.
As you fill the measuring cup with liquid, you need to look at which number the liquid is filled to, to determine how much liquid you have
A measuring cup can hold more than 1 "cup" of liquid (a cup is equal to 8 fluid ounces, see
US Standard Volume to learn more).
2.3 Read, Measure And Compare Volume Of Liquids
2.3.1 We use beaker or cylinder to measure the volumes of liquids. We read scales to the nearest litre or millilitre.
