Date: Week 21
Lesson Duration: 45 minutes
Week & Period: Week 21, Period 4
Topic: Functions of Flowering Plant Parts
Sub-topic: Functions of each part (roots absorb water, stem supports, leaves make food, flowers reproduce, seeds grow new plants)
Learning Objectives
By the end of the lesson, students should be able to explain the functions of the main parts of flowering plants and why each part is important.
Previous Knowledge
Students already know the names and appearances of plant parts from Week 20.
Instructional Materials
Real or potted plants, chart of plant parts with functions, markers, observation sheets, diagram worksheets
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks students how they think each part of a plant helps it grow. Students share guesses and examples from their observation of real plants.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Learners’ Activities (Expanded): Teacher explains the functions of each part of a flowering plant using a real plant, potted plant, or diagram:
- Roots: Absorb water and nutrients from soil, anchor the plant. Examples: taproots like carrot, fibrous roots like grass. Students gently touch roots and describe texture and length.
- Stem: Supports the plant, transports water and nutrients from roots to leaves. Examples: sunflower stem (soft), mango tree stem (woody). Students feel stems and note if they are hard, soft, tall, or short.
- Leaves: Produce food using sunlight (photosynthesis), exchange gases with the air. Students observe shape, edges, veins, and color. Examples: hibiscus leaf, spinach leaf. Students compare large vs. small leaves.
- Flowers: Reproduction, attract pollinators, produce seeds. Examples: marigold, hibiscus, sunflower. Students notice color, petals, and fragrance.
- Fruits: Protect seeds, help seed dispersal. Examples: mango, guava, tomato. Students examine fruits and identify seeds inside.
- Seeds: Grow into new plants. Students examine different seeds (bean, corn, pumpkin) and describe size, color, and texture.
Activities:
- Students match plant parts to their functions on a diagram or with real plant parts.
- Students draw a plant and write its functions beside each part.
- Sensory activity: Students touch roots, stems, leaves, and seeds and describe texture, flexibility, hardness, or softness.
- Group discussion: “Which plant part do we eat?” “Which part helps the plant make food?”
Assessment Checks:
- Oral questions: “What does the root do?” “Why is the stem important?” “How do leaves help the plant?”
- Worksheet activity: Students match plant parts with their correct functions.
- Observation: Teacher checks that students can identify and describe plant parts accurately and understand their roles.
- Peer assessment: Students explain plant parts and functions to each other in small groups.
Notes (Expanded & Detailed):
- Emphasize importance of each plant part for survival, growth, and reproduction.
- Encourage students to observe multiple plants to notice functional differences, e.g., thick stems for support, large leaves for more food production.
- Reinforce that roots, stems, leaves, flowers, fruits, and seeds all work together to keep the plant alive.
- Connect functions to real-life examples: roots anchor trees that give shade, leaves provide spinach for food, flowers attract bees for honey.
- Encourage students to record observations at home or in the school garden, noting plant parts and their functions.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Students review the main parts of flowering plants and their functions. Teacher reinforces how each part is necessary for plant growth and reproduction.
Evaluation Method (Expanded)
Exit slip/quiz: Students write one plant part and its function. Teacher collects slips and provides oral feedback.
Assignment (Expanded)
Students observe a plant at home or in the community, list its parts, and explain one function for each.
Follow-up Activity: Encourage students to grow a small plant and monitor how each part develops and functions.
Differentiation / Inclusive Strategies: Use hands-on observation and matching activities for students with varying learning styles. Pair students for discussion and reinforcement.
