INTRODUCTION

Volume is how much three-dimensional space a substance (solid, liquid, gas, or plasma) or shape occupies or contains, often quantified numerically using the SI derived unit, the cubic metre. The volume of a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid) that the container could hold, rather than the amount of space the container itself displaces.

Any unit of length gives a corresponding unit of volume, namely the volume of a cube whose side has the given length. For example, a cubic centimetre (cm³) would be the volume of a cube whose sides are one centimetre (1 cm) in length.

In the International System of Units (SI), the standard unit of volume is the cubic metre (m³). The metric system also includes the litre (L) as a unit of volume, where one litre is the volume of a 10-centimetre cube. Thus

1 litre = (10 cm)³ = 1000 cubic centimetres = 0.001 cubic metres,

Small amounts of liquid are often measured in millilitres, where

1 millilitre = 0.001 litres = 1 cubic centimeter.

Various other units of volume are also popular, including the cubic inch, the cubic foot, the cubic mile, the teaspoon, the tablespoon, the fluid ounce, the fluid dram, the gill, the pint, the quart, the gallon, the minim, the barrel, the cord, the peck, the bushel, and the hogshead.

Teaching Activities On Comparing Capacity Of Two Containers

Add caption

Here there are two learning activities based on some economical teaching aid were created each for high achiever and low achiever students, to help them understand better. By using this teaching aids, it seems make students feel really fun;

• containers brought by each group of pupils: a plastic container, an juice glass, two jelly cups

• green water color (for preparing the colored liquid)
  
  

Activity 1: Teaching Activities for high achiever students

Unit 10 :  Volume of Liquid

Learning Area :  Measure and compare volumes of liquid

Learning Objective :  Measure and compare volumes of liquid by using uniform non-standard units.

Learning Outcome : Pupils will be able to compare and measure volumes of liquid using uniform non-standard units.

Procedure:

1.                  Divide the class into groups of four students and have them work in their cooperative groups.

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

3.                  The teacher fills the plastic containers and the juice glass with some amount of green colour liquid.

4. Teacher asks the pupils to estimate which container holds more liquid.

5. Have the students to measure by pouring the liquid into the used jelly cups.

6. Get the pupils to record the number of cupfuls of liquid to check their estimation . The leader from each  group presents their record and make a conclusion.

7. Teacher summarises the lesson. Teacher explains that if the liquid in a container fills up more cupfuls  of liquid, it means that the container has larger volume. Tell the students do not judge the capacity  of liquids by their height if they are in different containers.

Activity 2: Teaching Activities for low achiever students

Unit 10 :     Volume of Liquid

Learning Area :    Measure and compare volumes of liquid

Learning Objective :   Measure and compare volumes of liquid by direct comparison .

Learning Outcome :   Pupils will be able to compare the volumes of two liquids by direct comparison.

Introductory Activities

Teacher shows two different containers that have some liquid. Ask the pupils to guess which container has a larger volume. Suggest to them how the volumes of the containers can be compared by pouring the liquid inside them into two similar containers.

Procedure:

      1. The teacher fills the plastic containers and the juice glass brought by the     students with different amount of green color liquid.

2. Work in pairs to find out which container has a larger volume.

3. The two students in the group pour the green color liquid into two similar containers—the used jelly cups.

4. The students compare their cups of liquid using a comparing card as shown in the diagram below.

5. Teacher summarizes the lesson. Tell the students that we can compare the capacity of liquids by their  height only if they are in the same containers.

How To Measure the Volume of a LIquid Using A Graduated Cylinder

Here show one video from the internet that show how volume of liquid are measured. Students will be more understand after watching this video and  hope they familiar with it when doing an activities that will be given.
