BASIC SCIENCE AND TECHNOLOGY
PREVIOUS LESSON –
TOPIC: MEASURING SOLID
1. Introductory Activities
2. Measuring the Volume of Regular Solid
3. Measuring the Volume of Irregular Solid
3. Lesson Evaluation and Weekly Assessment (Test)
By the end of the lesson, most of 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.
Meaning and Types of Solid – Regular and Irregular Shapes
The teacher will teach the lesson with the aid of:
1. Objects in the classroom e.g. cupboard, school box, books, etc.
4. Metre rule
9. Measuring cylinders.

CONTENT OF THE LESSON
LESSON 1 – INTRODUCTORY ACTIVITIES
Teacher’s Activities – Display a solid and liquid contents for the pupils to identify and differentiate.
Pupil’s Activities – This one is hard (solid) and this is watery (liquid).
Teacher’s remark – Correct. One of the content is solid and the other is liquid. We have learnt about the volume of liquid. This week will be solid.
Teacher’s Activities – Display sample or chart showing regular and Irregular shapes for the pupils to identify and differentiate.
Pupil’s Activities – Differentiate between the two shapes.
Teacher’s remark – The different between the two shapes is that, one of them is a regular shape while the other one is Irregular shape. Which of these shapes is regular and Irregular shape? For active participation and listening, give a cheer.
Teacher’s Activities – Organize the pupils into two or more groups depending on the size of the class. Provide each group with the necessary measuring tools/materials and sample of regular solid shapes with the following guided instructions.
identify the length, breadth and height of the shape and name them L, B and H.
measure and record the length, breadth and height as:
L= ____ cm
B = ____ cm
H = ____ cm
multiply all the lengths together.
write your result as ____ cm³.
Pupil’s Activities – Active participation in the group work.
Teacher’s remark – The result is known as volume. Celebrate the pupil’s active participation and discuss the volume of a solid shape on the board.
VOLUME OF A SOLID
Solid volume is the amount of space occupied by a solid object. That’s, the volume of a solid is the measure of how much space an object takes up.
The volume of a solid is measured in cubic units, i.e., cubic centimeter, cubic meter, etc.
Volume of a regular solid objects = Length x Breadth X Height (m³).
MORE EXAMPLES AND EXERCISES
Find the volume of the solid whose
1. L = 5 cm, B = 2 cm and H = 5 cm
2. 1. L = 10 m, B = 2 m and H = 5 m
3. 1. L = 8 cm, B = 4 cm and H = 12 cm
Find the length of a shape whose breadth is 4 cm, height is 2 cm and volume is 24 cm³.
LESSON 2 – INTRODUCTORY ACTIVITIES
Teacher’s Activities – Collect and write the results of the pupil’s assignment on the board without repeat any answer. Lead the working assignment.
Pupil’s Activities – Summit your assignment and participate in the working.
Teacher’s remark – Good job you for participate actively in the working assignment. Maintaining the existing groups, guide the pupils to measure and find the volume of Irregular shapes.
IRREGULAR SOLID OBJECTS
To measure the volume of a small irregular solid, follow the steps below:
1. Put some water in a measuring cup or cylinder.
2. Read the volume and record it.
3. Gently drop the object (i.e. irregular solid) into the liquid in the cylinder or cup.
4. Read the new volume and record it.
5. Substrate the first volume from the second volume.
