Measuring the volume of Solid Regular and Irregular Shapes
Week 10 :
Instructional Materials :
- Solid objects in classroom
- tin of milo
- Scheme of Work
- Online Information
- 9 Year Basic Education Curriculum
Previous Knowledge :
The pupils have previous knowledge of measuring liquid
Behavioural Objectives : At the end of the lesson, the pupils should be able to
- measure solid objects
- explain the basic unit of measuring solid shapes
- recite the mass measure table
- convert from from lower unit to higher unit and vice versa
- list solid shapes in classrooms and at home
Solid objects are those objects that can be seen , touched and felt. They are called solid because they are closely packed together firmly and they are strong . Examples of solid objects in school and at home are
- bags or rice etc.
The total space that an object occupied is known as the volume of the object.
Any matter that is a solid has a definite shape and a definite volume. Solid always have length, breadth and height .The molecules in a solid are in fixed positions and are close together. Solids have particles that are closed parked together .Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.
Matter that occupy solid spaces are called solid shapes. Their surfaces are called faces. Faces meet at edges and edges meet at vertices. Some examples of solid shapes: Cone, Cuboid, Sphere, Cylinder
Solid Shapes Are measured in Cubid centimetres
|1,000 cubic millimeters (mm3) =
||1 cu centimeter (cm3)
|1,000 cubic centimeters =
||1 cu decimeter (dm3)
||1,000,000 cu millimeters
|1,000 cubic decimeters =
||1 cu meter (m3)
The topic is presented step by step
The class teacher revises the previous topics
He introduces the new topic
The class teacher allows the pupils to give their own examples and he corrects them when the needs arise
- What are solid shapes
- What is the basic unit of measuring solid shapes
- Examples of solid shapes are _________ , __________, and ________
- Mention four solid items that are commonly found at home or in school
The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.
The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.
He or she does the necessary corrections when and where the needs arise.
