1. Multimedia Lesson Plan: Nutrition in Plants Integrated Science | Class 7 | Duration: 40 Minutes

2. Learning Objectives • Understand the concept of nutrition in plants • Identify types of nutrition • Explain the process of photosynthesis • Differentiate autotrophic and heterotrophic nutrition

3. Lesson Overview Subject: Integrated Science Topic: Nutrition in Plants Class: 7 Duration: 40 minutes Teaching Approach: Multimedia-based

4. Introduction Nutrition: process by which living organisms obtain food for growth and energy. Plants make their own food through photosynthesis.

5. Modes of Nutrition • Autotrophic Nutrition • Heterotrophic Nutrition

6. Autotrophic Nutrition • Plants prepare their own food using sunlight, carbon dioxide, and water. • This process is known as photosynthesis.

7. Photosynthesis Process • Occurs in the chloroplasts of plant cells. • Chlorophyll absorbs sunlight and converts it into chemical energy.

8. Raw Materials for Photosynthesis • Carbon dioxide (from air) • Water (from soil) • Sunlight (energy source) • Chlorophyll (green pigment)

9. Photosynthesis Equation 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ Carbon dioxide + Water → Glucose + Oxygen

10. Experiment Demonstration Test for starch in leaves: • Boil the leaf in water, then in alcohol. • Add iodine solution – blue-black color indicates starch.

11. Heterotrophic Nutrition Plants that depend on others for food. Types: Parasitic, Saprophytic, Symbiotic.

12. Parasitic Plants Examples: Cuscuta (dodder), mistletoe. They derive nutrients from host plants.

13. Saprophytic Plants Examples: Fungi, mushrooms. They feed on dead and decaying matter.

14. Symbiotic Plants Examples: Lichens, Rhizobium bacteria with leguminous plants. Mutual benefit relationship.

15. Interactive Quiz 1. What are the raw materials of photosynthesis? 2. Name one parasitic plant. 3. What color does a leaf turn when iodine is added to starch?

16. ICT / Multimedia Integration Use of animations, videos, and digital simulations to explain photosynthesis. Interactive quizzes via smartboard or Kahoot.

17. Class Activity Students draw and label parts of a leaf. Observe local plants and identify nutrition modes.

18. Assessment Methods • Oral questions • Quiz and worksheet • Observation of participation

19. Integration with Other Subjects • ICT: Using digital simulations • Art: Drawing plant structures • Math: Measuring growth rate

20. Real-Life Applications • Understanding food production in plants • Importance of green plants in oxygen balance

21. Recap • Nutrition is vital for plant growth. • Photosynthesis: key process for food preparation. • Some plants depend on others for food.

22. Learning Outcomes Students will be able to: • Describe photosynthesis clearly. • Identify various nutrition types in plants. • Relate concepts to real-life examples.

23. Homework / Assignment Write short notes on: 1. Autotrophic nutrition 2. Heterotrophic plants 3. Importance of chlorophyll

24. Teacher’s Reflection Lesson effectiveness: • Students showed interest through interactive videos. • Most could answer quiz questions accurately.

25. Conclusion Plants are essential for life on Earth as they prepare food and release oxygen. Understanding plant nutrition helps us appreciate nature’s balance.
