Below is a detailed two-week lesson plan for teaching Parts of Plants and Their Functions to Grade V students in India, aligned with the CBSE Science curriculum. This plan builds on foundational knowledge from Grade III, introducing more complex concepts like photosynthesis, transpiration, and seed dispersal, while remaining engaging and interactive for 10-11-year-olds. Each lesson is approximately 40 minutes long, assuming 5 classes per week.
Week 1: Exploring Plant Parts and Basic Functions
Day 1: Revisiting Plant Parts
Objective: Review the main parts of a plant and introduce their advanced roles.
Learning Outcomes: Students will identify roots, stems, leaves, flowers, fruits, and seeds, and describe their basic functions.
Materials: Potted plant, plant diagram, flashcards (plant parts), whiteboard, markers.
Activities:
- Warm-Up (5 mins): Show a potted plant and ask, “What parts do you remember from earlier grades?” List responses (e.g., root, leaf).
- Explanation (10 mins): Recap plant parts using a diagram:
- Roots: Anchor, absorb water/nutrients.
- Stem: Support, transport.
- Leaves: Food production.
- Flowers: Reproduction.
- Fruits: Protect seeds.
- Seeds: Grow new plants.
- Introduce advanced roles briefly (e.g., leaves in photosynthesis).
- Activity (20 mins):
- Flashcard Quiz: Show flashcards (e.g., stem) and ask students to name the part and one function.
- Group Discussion: In pairs, students list one function for each part on paper.
- Diagram Labeling: Worksheet to label plant parts and write one function.
- Wrap-Up (5 mins): Ask, “Why does a plant need all these parts?” Summarize: “Each part has a special job.”
Homework: Draw a plant, label its parts, and write one function for roots and leaves.
Day 2: Roots – Types and Functions
Objective: Explore root types and their detailed functions.
Learning Outcomes: Students will differentiate taproots and fibrous roots, and explain water/nutrient absorption.
Materials: Carrot (taproot), grass (fibrous root), magnifying glass, root diagram, water with food coloring.
Activities:
- Warm-Up (5 mins): Show a carrot and grass. Ask, “What part is this, and what does it do?”
- Explanation (15 mins): Discuss roots’ functions:
- Anchor plant, absorb water/nutrients, store food (e.g., carrot).
- Types: Taproot (one main root, e.g., radish), fibrous (many thin roots, e.g., wheat).
- Introduce nutrient absorption: Roots take in water/minerals from soil.
- Demo: Place a celery stalk in colored water to show absorption (observe next day).
- Activity (15 mins):
- Root Observation: Students examine roots with magnifying glasses, noting differences.
- Sorting Game: Provide pictures (e.g., beetroot, onion). Students classify as taproot or fibrous.
- Notebook Work: Draw and label a taproot and fibrous root.
- Wrap-Up (5 mins): Ask, “How do roots help a plant survive?” Summarize absorption and anchoring.
Homework: Write 3 sentences about roots’ jobs and list 2 plants with taproots.
Day 3: Stem – Structure and Transport
Objective: Understand the stem’s role in support and transport.
Learning Outcomes: Students will explain how stems support plants and transport water/nutrients.
Materials: Celery stalk (from Day 2 demo), sugarcane, potato, pictures of trees/creepers, straws.
Activities:
- Warm-Up (5 mins): Check celery from Day 2 (colored water absorbed). Ask, “How did the color reach the leaves?”
- Explanation (15 mins): Discuss stem functions:
- Support: Holds leaves/flowers (e.g., sunflower).
- Transport: Carries water/nutrients from roots to leaves, food from leaves to other parts.
- Storage: Some stems store food (e.g., potato).
- Types: Woody (trees), soft (herbs), creeping (pumpkin).
- Relate to demo: Stem acts like straws carrying water.
- Activity (15 mins):
- Straw Analogy: Students suck water through straws to mimic stem transport.
- Stem Sorting: Sort pictures by stem type (e.g., mango tree = woody, mint = soft).
- Observation: Examine sugarcane/potato, noting storage role.
- Wrap-Up (5 mins): Ask, “What happens inside a stem?” Summarize support and transport.
Homework: Find a plant at home, describe its stem (hard/soft), and write 2 sentences about it.
Day 4: Leaves – Photosynthesis Basics
Objective: Introduce leaves’ role in photosynthesis and gas exchange.
Learning Outcomes: Students will explain how leaves make food and describe leaf features.
Materials: Leaves (mango, tulsi), magnifying glass, diagram of photosynthesis, green chart paper.
Activities:
- Warm-Up (5 mins): Show a leaf and ask, “What does this do for a plant?” Recall food-making.
- Explanation (15 mins): Introduce:
- Photosynthesis: Leaves use sunlight, water, and carbon dioxide to make food (sugar), releasing oxygen.
- Key parts: Chlorophyll (green color), stomata (tiny holes for gas exchange).
- Example: “Leaves are like kitchens for plants.”
- Discuss leaf shapes/veins (e.g., neem vs. banana).
- Activity (15 mins):
- Leaf Observation: Examine leaves with magnifying glasses, noting veins and texture.
- Photosynthesis Role-Play: Students act as sunlight, water, and leaves to show food-making process.

Homework: Write a short paragraph (4-5 sentences) on how leaves make food.
Day 5: Flowers – Reproduction and Pollination
Objective: Understand flowers’ role in reproduction and pollination.
Learning Outcomes: Students will describe how flowers help plants reproduce and identify pollination agents.
Materials: Real flowers (marigold, hibiscus), flower diagram, pictures of bees/butterflies, magnifying glass.
Activities:
- Warm-Up (5 mins): Show a marigold. Ask, “What job does a flower have?”
- Explanation (15 mins): Explain:
- Flowers produce seeds for new plants (reproduction).
- Parts: Petals (attract insects), stamens (male, pollen), pistil (female, seeds form).
- Pollination: Pollen moves from stamen to pistil (by bees, wind, butterflies).
- Example: “Bees carry pollen while collecting nectar.”
- Activity (15 mins):
- Flower Dissection: In groups, gently dissect a flower to identify petals, stamens, pistil (teacher-guided).
- Pollination Game: Students act as bees, moving “pollen” (paper bits) between flowers.
- Worksheet: Label flower parts and match pollinators (bee, wind) to flowers.

Activities:
- Warm-Up (5 mins): Show an apple. Ask, “What’s inside this fruit?” (Seeds).
- Explanation (15 mins): Discuss:
- Fruits protect seeds and help them spread.
- Seed dispersal methods:
- Wind (e.g., dandelion).
- Animals (e.g., mango eaten by birds).

Activities:
- Warm-Up (5 mins): Ask, “What happens to water in a plant?” Recall transport.
- Explanation (15 mins): Introduce:
- Transpiration: Leaves release water vapor through stomata, helping cool plants and pull water up.
- Adaptations: Leaves vary by environment (e.g., cactus = needle-like to save water, lotus = waxy to repel water).
- Example: “Desert plants have small leaves to reduce water loss.”
- Activity (15 mins):

Notes for Teachers
- Cultural Context: Use Indian plants like mango, tulsi, and neem to make lessons relatable. Reference festivals like Diwali (marigold) for engagement.
- Engagement: Hands-on activities (dissection, germination) and demos (transpiration) keep students curious.
- Inclusivity: Adapt for diverse learners with visuals, group work, or oral explanations. Ensure safety during dissections (no sharp tools).
- Assessment: Monitor homework, participation, quiz, and project to gauge understanding. Provide constructive feedback.
- Resources: Use local plants and simple materials. I can provide worksheets or a sample video link if needed!
- Connection to Past Requests: Drawing from your interest in interactive Grade III plant lessons (April 13, 2025), I’ve included hands-on activities like germination and dissection, scaled up for Grade V with concepts like photosynthesis and transpiration for deeper understanding.
