LEARNING OBJECTIVES

By the end of the lesson, pupils should be able to:

1. Explain the meaning of measuring liquids.

2. Identify metric units used for measuring liquids.

3. Mention materials used for measuring liquids.

4. Measure the volume of liquids correctly.

5. Improvise a simple measuring cylinder.

ENTRY BEHAVIOUR

Pupils have previously learned about liquids such as water, milk, oil, and other substances found in their environment.

This lesson builds on that knowledge by helping pupils understand that liquids can be measured using standard units and measuring instruments to determine their exact volume for cooking, science activities, and daily life uses.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Measuring cylinder

2. Measuring cup

3. Water

4. Plastic bottle

5. Funnel

6. Marker

7. Ruler

8. Charts showing metric units

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

INTRODUCTION

Liquids are used every day for drinking, cooking, washing, and many other activities. To know the exact quantity of a liquid, we measure it using special instruments and units.

LESSON 1 – MEANING OF MEASURING LIQUIDS

Measuring liquids is the process of finding the amount or volume of a liquid using measuring instruments.

METRIC UNITS FOR MEASURING LIQUIDS

1. Litre (L)

2. Millilitre (mL)

RELATIONSHIP BETWEEN LITRE (L) AND (MILLILITRE mL)

1 Litre = 1000 Millilitres

MATERIALS USED FOR MEASURING LIQUIDS

1. Measuring cylinder

2. Measuring cup

3. Measuring jug

4. Beaker

5. Graduated bottle

LESSON 2 – MEASURING THE VOLUME OF LIQUIDS (HAND-ON-ACTIVITIES)

The volume of a liquid is measured by:

1. Pouring the liquid into a measuring cylinder or measuring cup.

2. Placing the instrument on a flat surface.

3. Reading the level of the liquid carefully.

4. Recording the measurement in litres or millilitres.

LESSON 3 – IMPROVISING A MEASURING CYLINDER (HAND-ON- ACTIVITIES)

Materials Needed

Transparent plastic bottle

Ruler

Marker

Water

Procedure

1. Wash and dry the plastic bottle.

2. Use a ruler to mark equal divisions on the bottle.

3. Label the divisions as 100 mL, 200 mL, 300 mL, etc.

4. Pour water into the bottle and check the markings.

5. Use the improvised cylinder for measuring liquids.

IMPORTANCE OF MEASURING LIQUIDS

1. It helps obtain accurate quantities.

2. It is useful in cooking and science experiments.

3. It prevents waste of liquids.

4. It helps in trade and business.

WEEKLY ASSESSMENT/TEST QUESTIONS AND ANSWERS/HOMEWORK
