1. Introduction

2. Parts of Flowers

3. Sexual Reproduction

4. Parts of a flower that produce fruit

5. Meaning and Types of Pollination

6. Agents and Process of Pollination

7. Lesson Evaluation and Weekly Assessment (Test)

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. identify parts of a flower.

2. draw and label parts of a flower.

3. identify parts of flower that produce fruit.

4. explain the meaning of pollination.

5. state types of pollination.

6. list the agents of pollination.

7. illustrate the process of pollination.

ENTRY BEHAVIOUR

The pupils can identify different 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.

For examples,

1. Aloe Vera

2. Hibiscus

3. Orchids

4. Calla Lilly

5. Cacati

6. Climbing ivy

7. Cordyline

8. Dumb cane

9. Red acalypha

10. Yellow bush, etc.

Some flowers produce the seeds that can become new plants while some flowers don’t.

PARTS OF FLOWERS 

1. Pistil

• Stigma

• Style

• Ovary

2. Stamen

• Anther

• Filament

 

3. Calyx

4. Stem

LESSON EVALUATION/ASSIGNMENT 

1. Draw and colour a hibiscus flowers.

2. Find out the different between anther to the stigma.

LESSON 2 – PARTS OF THE FLOWER THAT PRODUCE FRUIT

The part of flower that produce fruit is called ovary.

Ovary is where seeds are produced which later grow into young plants.

The ovary and the surrounding parts later become the fruit.

Ovary is also called as the seed box.

MEANING OF POLLINATION

Pollination is the process of moving pollen grains from the anther to the stigma.

Once the bee carried the pollen grains from anther to the stigma, fertilization begins.

Apart from insects, pollination also take place when the winds blow.

TYPES OF POLLINATION

There are two types of pollination –

1. Self pollination

2. Cross pollination

SELF POLLINATION

Self pollination is the movement of pollen grains from the anther to the stigma with the same flower.

CROSS POLLINATION 

Cross pollination is the movement of pollen grains from the anther of one flower to the stigma of different flower.

ASSIGNMENT

Discuss the process of reproduction in chicken and goat.

LESSON 3 – INTRODUCTION

Male and female of animal of the same type mate. That’s male and female chicken and goat.

After mating, the female chicken (ducks, pigeons, etc.) lay eggs. These eggs later hatch into young once.

In other animals like goat, dogs, sheep, cows, etc., after male and female mate, the female carries pregnancy and later gives birth to the young animal alive.

Life in both plants and animals begin when a male meets a female to produce their young ones.

Both the male and the female parts of plant are in the flower. 

AGENTS OF POLLINATION

Agents of pollination Pollinating agents are –

1. animals such as insects, birds, and bats

2. water

3. wind

4. Insects and Winds are the major types of pollination.

5. Man

PROCESS OF POLLINATION

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.

The male part of a flower must first join with the female part.

Pollen contains the male part.

The female egg cell is inside the ovule. When the male and female parts join, we say fertilization has taken place.

 

SHORT DRAMA ON POLLINATION (ANTHER, STIGMA AND BEE) 

Pupil’s role –

• A boy acts as anther (anther contains pollen grains).

• A girl acts as stigma.

• A boy or girl as bee.

Teacher’s activities – Lead the guided instructions to discuss what next with anther and stigma after meeting.

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. Takes pupils for a walk within and around the school to collect the available common flowers.

Pupil’s Activities – Bring flowers to the class, Identify and name each of the flower collected.

3. Uses the flowers collected to introduce the lesson.

4. Asks pupils draw a flower on the chart and labels its parts.

Pupil’s Activities – Draw a flower and label its parts.

5. Provides sample of flowers like hibiscus and guides the pupils to identify parts of a flower. Or chart showing parts of flower.

Pupil’s Activities – Identify each parts of a flower.

6. Names each of the flower and shows the pupils to identify parts of a flower that produce fruit.

Pupil’s Activities – Identify parts of a flower that produce fruit.

7. Takes pupils for a walk within and around the school and call their attention to different activities that occur within and around the flowers. For example, the flies, Insects or birds.

8. Asks pupils to discuss the activities of the flies, Insects or birds on flowers.

Pupil’s Activities – Identify and discuss the activities of Insects, flies and birds.

9. Uses pupils responses to introduce the meaning and types of of pollination.

Pupil’s Activities – Pay attention to the lesson introduction to understand the meaning and types of of pollination.

10. Introduces flies, Insects or birds as agents of pollination and state other agents.

Pupil’s Activities – State the agents of pollination.

11 . Asks pupils to differentiate between the process of reproduction in chicken and goat.

12. Listen to the pupils, uses their responses to discuss the process of pollination in plants.

Pupil’s Activities – Differentiate between the process of reproduction in chicken and goat. Also, pay attention to the process of pollination.

13. Guides pupils to demonstrate how the process of pollination.

Pupil’s Activities – Participate actively in the demonstration.

14. 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.
