Grade Level: Grade 5
Date: Week 22
Lesson Duration: 45 minutes
Week & Period: Week 22, Period 4
Topic: One Organized System in Plants
Sub-topic: Plant respiration, photosynthesis, basic plant systems
Learning Objectives
By the end of the lesson, students should be able to explain plant respiration, give an overview of photosynthesis, and identify basic plant systems such as roots, stems, and leaves
Previous Knowledge
Students already know the basic parts of plants and their functions
Instructional Materials
Plant charts, diagrams of photosynthesis, live plants, handouts
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Learners’ Activities (Expanded): Students discuss whether plants “breathe” and how they get food
Assessment Checks: Teacher asks how plants survive without eating like humans
Notes (Expanded & Detailed): Encourage critical thinking and curiosity about plant life
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Learners’ Activities (Expanded): Teacher introduces plant respiration and photosynthesis using clear, colorful diagrams of leaves, stems, roots, and stomata. Teacher explains that respiration allows plants to “breathe,” taking in oxygen and releasing carbon dioxide, while photosynthesis allows plants to make food using sunlight, water, and carbon dioxide. Learners label diagrams of leaves showing stomata, chloroplasts, and veins. Teacher demonstrates a simple experiment: placing a leaf under sunlight and another in darkness, then testing for starch using iodine solution to show photosynthesis in action. Hands-on activity: learners place leafy branches in water and observe bubbles forming to show oxygen release. Group activity: learners create a flow chart of photosynthesis and respiration steps. Real-life examples are given: plants in the garden, trees producing oxygen, and crops providing food.
Assessment Checks: Teacher asks learners to identify plant parts involved in photosynthesis and respiration, explain what each plant needs to make food, and describe what happens when sunlight is absent. Learners demonstrate understanding by drawing labeled diagrams, explaining experiments, and answering scenario-based questions (e.g., “What happens to a plant at night?”).
Notes (Expanded & Detailed): Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose (food) and oxygen. Respiration is the process of breaking down glucose to release energy, taking in oxygen and releasing carbon dioxide. Key examples include: leaves as the main photosynthesis site, sunlight as energy, water absorbed from roots, carbon dioxide from the air, and oxygen released into the atmosphere. Experiments with iodine or bubble observation reinforce understanding. Encourage learners to connect plant processes to human life, like the oxygen we breathe and food we eat. Practical tips: placing plants in different light conditions to observe changes, and comparing leafy vegetables’ color and growth as a measure of photosynthesis efficiency.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Students summarize plant respiration, photosynthesis, and identify roots, stems, and leaves
Evaluation Method (Expanded)
Exit slip/quiz: Students write one function of roots, stems, or leaves
Teacher will collect slips and provide oral feedback
Assignment (Expanded): Draw a labeled diagram showing plant systems and explain photosynthesis briefly
Follow-up Activity: Observe a plant over a week to see changes and record findings
Differentiation / Inclusive Strategies: Use live plants and visual diagrams to aid learning
