C: PREVIOUS KNOWLEDGE
The pupils have learnt about domestic animals, the skeletal system, joints and muscles, reproduction in plants, the water cycle, rocks, acids and bases, and soap and detergents during the second term.
D: PERFORMANCE OBJECTIVES
By the end of the lesson, pupils should be able to:
- Classify domestic animals according to their feeding and reproduction.
- Identify major bones, joints and muscles.
- Explain pollination and fertilization in plants.
- Describe the water cycle and rain formation.
- Identify the major types of rocks.
- Differentiate between acids and bases.
- Explain the uses and safe handling of soap and detergents.
E: CONTENT
Revision of Domestic Animals
Domestic animals are animals kept by humans for different purposes. Examples include:
- Cow.
- Goat.
- Chicken.
- Dog.
- Cat.
Animals may be:
- Herbivores – eat mainly plants.
- Carnivores – eat mainly animal materials.
- Omnivores – eat both plant and animal materials.
Some animals give birth, while others lay eggs.
Revision of the Skeletal System
The skeleton is the framework of bones in the body. Its functions include:
- Support.
- Protection.
- Movement.
- Giving the body shape.
A joint is where two or more bones meet. Muscles help move bones.
Revision of Plant Reproduction
A flower contains reproductive parts. Pollination is the transfer of pollen from anther to stigma. Fertilization is the joining of male and female reproductive cells. After fertilization:
- Ovule → seed.
- Ovary → fruit.
Revision of the Water Cycle
The stages are:
- Evaporation
- Condensation
- Precipitation
- Collection
☀️ → 💧 → ☁️ → 🌧️
Revision of Rocks
The three major types are:
- Igneous rocks.
- Sedimentary rocks.
- Metamorphic rocks.
Rocks are used for buildings, roads, monuments and other purposes.
Revision of Acids and Bases
Examples of acids include:
- Lemon juice.
- Vinegar.
Examples of bases include:
- Soap solution.
- Baking soda solution.
Unknown chemicals should never be tasted.
Revision of Soap and Detergent
Soap and detergents are cleaning substances. They are used for:
- Bathing.
- Washing clothes.
- Cleaning dishes and surfaces.
Strong soap-making chemicals must only be handled with proper safety measures.
F: LESSON PRESENTATION
F1: Teachers’ Activities
- Revises domestic animals and their feeding.

- Reviews the skeleton, joints and muscles.
- Revises pollination and fertilization.
- Reviews the water cycle.
- Revises types and uses of rocks.
- Reviews acids and bases.
- Revises soap and detergent.
- Asks oral and written revision questions.
F2: Pupils’ Activities
- Classify domestic animals.
- Identify bones and joints.
- Explain how muscles help movement.
- Explain pollination and fertilization.
- Arrange the stages of the water cycle.
- Name the three major types of rocks.
- Give examples of acids and bases.
- State uses of soap and detergents.
- Answer revision questions.
G: CONCLUSION
The teacher revises the major topics taught during the second term and corrects pupils where necessary. The teacher encourages pupils to study their notes, observe science in their surroundings and practise safe behaviour during practical activities.
