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. name the parts of the flower involved in fertilization.
2. identify parts of a flower that are concerned with pollination and fertilization.
3. describe stages of development from flower to fruit.
4. distinguish between pollination and fertilization.
ENTRY BEHAVIOUR
The pupils can identify parts of flowers.
INSTRUCTIONAL MATERIALS
The teacher will teach the lesson with the aid of:
1. Life flowers e.g. hibiscus, cowpea flower
2. Chart or diagram of a flower, agents of pollination, development from flower to fruits.
3. Drawing book
4. Pencil.
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
LESSON 1 – INTRODUCTION
Flowers are part of the plants that are very attractive and beautiful.
Quick Groups or Pairs Activity – Identify and name each part of the above flower.
PARTS OF THE FLOWER INVOLVED IN FERTILIZATION
Anther and stigma are parts of the flower that involve in fertilization.
The male part of the flower is called anther.
The female part of the flower is called stigma.
The anther contains pollen.
The anther transfers pollen to the stigma.
This is process is called pollination.
This is how seeds or plants are produced.
LESSON 2 – PARTS OF A FLOWER THAT ARE CONCERNED WITH POLLINATION AND FERTILIZATION
The parts of a flower that are concerned with pollination and fertilization are pistil and stamen –
1. Pistil
- Stigma
- Style
- Ovary
2. Stamen
- Anther
- Filament
STAGES OF DEVELOPMENT FROM FLOWER TO FRUIT
Plants (flowers) are living things.
They grow and reproduce like any other living thing.
The stages of flower from fruits follow a cyclic process of starting a new life, growing, and then coming back to the starting stage (reproducing).
There are the 5 stages of development from flower to fruit –
- Seed
- Germination
- Growth
- Reproduction
- Pollination, and
- Seed spreading stages
LESSON 3 – DIFFERENT BETWEEN POLLINATION AND FERTILIZATION
Pollination is the transfer of pollen from Anther to Stigma of a flower.
The process of pollination is called fertilization.
Fertilization is the joining together of the male part of the pollen to the female ovules in the ovary.
REVISION AND WEEKLY ASSESSMENT (TEST)
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. Displays sample of flower or chart.
3. Asks pupils to identify and name each part of the flower.
Pupil’s Activities – Identify and name each part of the flower.
4. Uses the flower and pupil’s responses to introduce the lesson.
3. Leads a discussion on parts of a flower that are concerned with pollination and fertilization.
Pupil’s Activities – Pay attention to the lesson introduction and participate actively in the lesson discussion.
4. Displays chart showing stages of development from flower to fruit.
5. Asks pupils to examine the chart and identify each stage of development from flower to fruit.
6. Discuss the stages of development from flower to fruit.
Pupil’s Activities – List and explain the stages of development from flower to fruit.
7. Asks pupils to differentiate between pollination and fertilization.
Pupil’s Activities – Differentiate between pollination and fertilization.
8. Summarizes the lesson on the board.
Pupil’s Activities – Participate actively in the summary of the lesson and write as instructed.
CONCLUSION
To conclude the lesson for the week, the teacher revises the entire lesson and links it to the following week’s lesson.
