Elemenentary Grade 3 - 5

1. Who prepares food for you? Why do we need food? Where does the food we eat come from?

2. Do Plants need food? Who prepares food for them?

3. THE BASICS OF PHOTOSYNTHESIS Ms. Neetu Science Year 4

4. LEARNING OBJECTIVES At the end of the lesson, pupils should be able to: 1 2 3 explain the process of photosynthesis understand how photosynthesis works explain the importance of photosynthesis

5. Story Time Sunny’s Big Breakfast: A Photosynthesis Story

6. One bright morning, Sunny the Sunflower woke up with a big stretch. “Ahh, what a lovely day!” he said, shaking his golden petals. As the sun rose higher, Sunny felt warm and happy. “Time for breakfast!” he thought. But Sunny didn’t need to eat like humans or animals. Instead, he had a special trick—he could make his own food!

7. Sunny stretched his green leaves wide. Inside them was chlorophyll, a magic green helper that trapped sunlight.

8. “Come on, Sun, let’s get to work!” Sunny’s leaves worked like tiny kitchens. With sunlight, water from his roots, and air from the sky, Sunny made his own food called glucose. Thanks to chlorophyll, all the ingredients mixed together in a special process called photosynthesis.

9. “Yay! I made my food!” Sunny cheered This gives me energy to grow big and strong!” . “Now I have the power to bloom even brighter !”

10. As he grew, he also released oxygen into the air. “Breathe in, world!” By the end of the day, Sunny felt proud. He had eaten, grown, and helped the world breathe—all thanks to chlorophyll and the magic of photosynthesis! As night fell, Sunny smiled. “Thank you, Sun! See you tomorrow for another bright and yummy day!” The End.

11. Who is the main character of the story? How does Sunny make his own food? What is the special green helper in Sunny’s leaves called? What three things does Sunny need for photosynthesis? What food does Sunny make to get energy? What does Sunny release into the air that helps humans and animals breathe? Why does Sunny thank the Sun at the end of the story? What would happen if Sunny didn’t get sunlight?

12. WHAT IS PHOTOSYNTHESIS?

13. PHOTO - LIGHT SYNTHESIS - TO PUT TOGETHER the making of food in the presence of light is photosynthesis

14. WHAT DO PLANTS NEED FOR PHOTOSYNTHESIS?

15. What do plants need? Sunlight 🌞 Water 💧 Carbon Dioxide (Air) 🌬️ Chlorophyll (Makes plants green!) 🍃 THE INGREDIENTS FOR PHOTOSYNTHESIS

16. PHOTOSYNTHESIS Photosynthesis is a process by which plants prepare their own food in the presence of sunlight with the help of water, carbondioxide and chlorophyll.

17. WATER Plants need water to mix with the carbon dioxide and sunlight. Sunlight serves as the primary source of energy for plants. SUNLIGHT

18. CHLOROPHYLL Chlorophyll captures the sunlight and helps turn it into food. CARBON DIOXIDE Plants require carbon dioxide from the atmosphere.

19. WHERE DOES PHOTOSYNTHESIS WORK?

20. Photosynthesis takes place in the leaves of a plant, specifically in tiny structures called chloroplasts

21. Plants appear green because they contain a pigment called chlorophyll, which absorbs light from sun

22. They take in carbon dioxide (CO₂) from the air. They release oxygen (O₂), which we breathe! At night, they also take in oxygen like us. STOMATA

23. WHY IS PHOTOSYNTHESIS IMPORTANT?

24. 🌱 Produces Oxygen – Plants release oxygen, which humans and animals need to breathe. 🌞 Makes Food – It helps plants create their own food, which supports all life on Earth. 🌎 Maintains Balance – It removes carbon dioxide from the air, keeping the atmosphere balanced. 🍎 Supports the Food Chain – All animals depend on plants for food, directly or indirectly. 🌿 Provides Energy – The energy stored in plants is passed through the food chain when we eat them.

25. ACTIVITY Take a deep breath—thank a plant!

26. LET'S PLAY A GAME! Photosynthesis Charades

27. QUICK QUIZ?? WHAT DID WE LEARN? Questions: What do plants need for photosynthesis? What gas do plants give us? Why is photosynthesis important? What is plant’s food called? What is the green substance called?

28. QUICK QUIZ?? f. where does the exchange of gases happens in a plant? g. What part of plants absorb water from the soil? h. Where does Photosynthesis mainly occur in plants?

29. THANK YOU! Now you know the secret of plant magic! Keep exploring and learning!
