Keywords:

• Flower
• Pollination
• Pollen

• Pistil
• Agents of Pollination

Set Induction:

The teacher will bring a real flower to the class and ask the pupils to observe and describe what they see.

Entry Behaviour:

Pupils have a basic understanding of plants and their importance in the environment.

Learning Resources and Materials:

• Real flowers
• Diagrams of a flower
• Charts showing the process of pollination
• Drawing materials (pencils, paper, rulers)

Building Background/Connection to Prior Knowledge:

The teacher will connect the lesson to previous topics on plant growth and explain how flowers play a key role in the reproduction process of plants.

Embedded Core Skills:

• Observation
• Critical thinking
• Illustration
• Collaboration

Learning Materials:

• Basic Science Textbook for Primary 5
• Notebooks
• Writing and drawing materials

Reference Books:

• Lagos State Scheme of Work
• Basic Science Textbook for Primary 5

Instructional Materials:

• Diagrams of a flower
• Visual aids showing the process of pollination

Content:

1. Parts of a Flower:
   • Petals: The colorful parts that attract pollinators.
   • Sepals: The green parts that protect the flower bud.
   • Stamen: The male part that produces pollen (includes anther and filament).
   • Pistil: The female part that receives pollen (includes stigma, style, and ovary).
   • Ovule: Found inside the ovary; develops into seeds after fertilization.
2. Pollination:
   • Meaning: The process by which pollen is transferred from the stamen (male part) to the pistil (female part) of a flower.
   • Types of Pollination:
     • Self-Pollination: Pollen from the same flower or another flower on the same plant fertilizes the ovule.
     • Cross-Pollination: Pollen from a flower on one plant fertilizes a flower on a different plant.
   • Process of Pollination: Involves the transfer of pollen grains from the anther to the stigma of a flower.
   • Agents of Pollination:
     • Insects: Bees, butterflies
     • Wind: Carries pollen from one flower to another
     • Water: Transfers pollen in aquatic plants
     • Animals: Birds, bats, etc.
3. Development After Pollination:
   • The pollen travels down the style to the ovary.
   • Fertilization occurs when pollen fuses with the ovule.
   • The ovule develops into seeds, and the ovary becomes the fruit.

Class Activity Discussion:

1. Name the parts of a flower.
2. What is pollination, and why is it important?
3. Differentiate between self-pollination and cross-pollination.
4. List two agents of pollination.
5. What happens after a flower is pollinated?
6. Describe the role of insects in pollination.
7. What part of the flower becomes the fruit?
8. How does wind help in pollination?
9. Why is cross-pollination important for plant diversity?
10. Draw and label the parts of a flower.

Presentation:

Step 1:
The teacher revises the previous topic on environmental quality and introduces the new topic on reproduction in plants.

• Ask pupils to mention what they know about flowers.

Step 2:
The teacher introduces the new topic as follows:

• Explain that today’s lesson will focus on understanding the parts of a flower and how pollination helps plants reproduce.

Step 3:
The teacher allows the pupils to give their own contributions and the teacher corrects the pupils when and where necessary.

• Pupils will observe a real flower, identify its parts, and draw and label the parts in their notebooks.
• Facilitate a discussion on the types and agents of pollination.

Teacher’s Activities:

• Guide pupils in identifying the parts of a flower.
• Explain the process of pollination and the role of different agents.
• Encourage pupils to draw and label the parts of a flower.
• Illustrate the process of pollination using charts.

Learners’ Activities:

• Participate in identifying and drawing the parts of a flower.
• Discuss and list the types of pollination and their agents.
• Work in pairs to illustrate the process of pollination.
• Engage in group discussions on the importance of pollination.

Evaluation Questions:

1. What are the parts of a flower?
2. Explain the process of pollination.
3. Name the agents of pollination.
4. What is the difference between self-pollination and cross-pollination?
5. What happens to the ovule after pollination?
6. How do insects contribute to pollination?
7. What part of the flower becomes the seed?
8. Why is pollination important for plants?
9. How does water act as an agent of pollination?
10. Draw and label the parts of a flower.

Conclusion:

The teacher goes around to assess the pupils’ understanding of the parts of a flower and the process of pollination. The teacher emphasizes the importance of pollination in the reproduction of plants.
