WEEK 10

PRIMARY 4

THEME –

TOPIC: MEASURING SOLID

Solid volume is the amount of space occupied by a solid object.

PERFORMANCE OBJECTIVES

By the end of the lesson, the pupils should have attained the following objectives (cognitive, affective and psychomotor) and should be able to –

1. measure the volume of regular solids;
2. measure the volume of irregular solids.

ENTRY BEHAVIOR

Meaning and Types of Solid – Regular and Irregular Shapes

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Objects in the classroom e.g. cupboard, school box, books, etc.
2. Stone
3. Water
4. Metre rule
5. Tape
6. Rule
7. Beakers
8. Measuring cylinders.

REFERENCE MATERIALS

1. 9 – Years Basic Education Curriculum
2. Lagos State Scheme of work
3. Basic Science and Technology
4. All Relevant Materials
5. Online Materials

CONTENT OF THE LESSON

MEASURING SOLID

volume of a regular solid objects = Length x Breadth X Height (m3)

volume of an irregular solid objects

= volume of object + water – volume of water (m3)

MEASURING THE VOLUME OF OBJECTS

Regular Solid Objects

Measuring the length, breadth and height of the following and record the values in the right. Find the volumes.

Irregular Solid Objects

To measure the volume of a small irregular solid, follow the steps below:

• Put some water in a measuring cup or cylinder.
• Read the volume and record it.
• Gently drop the object (i.e. irregular solid) into the liquid in the cylinder or cup.
• Read the new volume and record it.
• Substrate the first volume from the second volume.

PRESENTATION

To deliver the lesson, the teacher adopts the following steps:

1. To introduce the lesson, the teacher revises the previous lesson. Based on this, he/she asks the pupils some questions;
2. Provides the pupils with standard instructions for measuring length;
3. Pupil’s Activities – Measure the length (L), breath (B), and height (H) of thing in the classroom.
4. Guides the pupils to measure the length (L), breath (B) of selected regular objects correctly; and compute the volumes in metic units metre cube.
5. Pupil’s Activities – Use their measurements to compute the volume of the objects as: (V = L x B x H m3).
6. Demonstrates how to determine the volume of irregular solids e.g. stone by displacement method.
7. Pupil’s Activities – Measure volume of a stone (irregular objects) by the displacement method.

CONCLUSION

To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.

LESSON EVALUATION

Pupils to:

1. measure the volume of regular solids;
2. measure the volume of irregular solids.

Great is thy faithfulness

O’Lord.
