Introduction (10 - 15 minutes)

1. Recap of related topics (3-4 minutes):

   • The teacher reminds the students of the basic knowledge of plants that they have learned in previous classes.
   • The teacher asks the students to recall what they know about how plants grow and what they need for growth (sunlight, water, and nutrients).
   • The teacher reminds the students of the concept of ecosystems.

2. Problem-Situations (3-4 minutes):

   • The teacher proposes a problem: "Imagine a world where the sun doesn't shine. What would happen to plants?".
   • The teacher proposes a second problem: "If we stopped watering a plant but it still has sunlight, will it survive? Why or why not?".

3. Real-life application (2-3 minutes):

   • The teacher explains that understanding photosynthesis can help us understand why plants are important for the environment and for human survival.
   • The teacher emphasizes the importance of photosynthesis in the production of oxygen, which humans and animals need to breathe, and the absorption of carbon dioxide, which helps mitigate global warming.

4. Attention-grabbing introduction (3-4 minutes):

   • The teacher shares a curious fact: "Did you know that even though plants are green, they absorb all colors of light except green? That's why they appear green to us!".
   • The teacher introduces the topic by saying, "Today, we are going to learn about a magical process that plants perform, a process that allows them to create their food using just sunlight, water, and air. This process is called photosynthesis."
   • The teacher shares another interesting fact: "Without photosynthesis, there would be no life on earth as we know it. It provides the oxygen we breathe and the food we eat. Amazing, isn't it?"

Development (20 - 25 minutes)

1. Pre-Class Activities (10 - 15 minutes):

   a. Digital Resource Analysis (5 - 7 minutes): - The teacher sends out a link to a short, engaging video that explains photosynthesis in simple terms. - Students are encouraged to watch the video at home, taking notes on the process, the components involved and the importance of photosynthesis to life on earth.

   b. Reading Assignment (5 - 7 minutes): - The teacher provides an online article or digital textbook section that further explains photosynthesis. - Students are assigned to read the material and write down any questions or points of confusion they have.

   c. Visual Representation (5 - 8 minutes): - Students are asked to sketch a simple diagram of photosynthesis they saw in the video and the article, labeling the process and its inputs and outputs.

2. In-Class Activities (15 - 20 minutes):

   a. Group Discussion and Presentation (10 - 12 minutes): - The teacher divides the class into groups of 4 - 5 students. - Each group discusses their understanding of photosynthesis based on the pre-class activities, addressing any questions or points of confusion. - Each group then presents their understanding of the topic to the class with one member explaining their drawn diagram to the class.

   b. Photosynthesis in Action (10 - 15 minutes): - The teacher creates a playful and engaging role-play activity. The students are asked to perform 'Photosynthesis Live', a theatrical representation of photosynthesis. - Students in a group represent different elements (Sunlight, Water, Carbon dioxide) and also Chloroplasts, the site of photosynthesis. - Students, embodying their roles, act out the process of photosynthesis. This is carried out in the following manner: 1) The student representing sunlight "shines" on the student representing the plant. 2) The student embodying water then "provides" water to the plant. 3) The student embodying carbon dioxide "blows" carbon dioxide. 4) Within the plant, students representing Chloroplasts "catch" the light, water, and carbon dioxide, and then "produce" oxygen and glucose (depicted by holding up picture cards). - This performance is done twice, to ensure understanding through repetition. - This activity turns an abstract concept into a visual, physical experience to help deepen understanding.

Finally, the teacher wraps up this segment by ensuring that any last doubts about the process of photosynthesis are cleared. Notes from the presentations may be consolidated and shared with the class for revising the concept at home. This paves the way for the closing of the lesson in the subsequent stage. The role-play activity helps in making the concept of photosynthesis enjoyable and memorable for the students.

Feedback (5 - 10 minutes)

1. Group Sharing (3 - 5 minutes):

   • Each group is given up to 3 minutes to share their conclusions from the group activities, explaining how they connected the role-play activity to the theoretical knowledge of photosynthesis.
   • The teacher facilitates this discussion, ensuring that all students participate and understand the connections between the activity and the theory.

2. Assessment of Learning (2 - 3 minutes):

   • The teacher assesses what was learned from the group activities.
   • The teacher asks probing questions to ensure that students understand the concept of photosynthesis, its process, and its importance in the ecosystem. For example, "What happens to a plant if it doesn't get sunlight?" or "How does photosynthesis contribute to life on earth?".
   • The teacher also encourages students to ask any remaining questions or share any points of confusion that they have.

3. Reflection Time (2 - 3 minutes):

   • The teacher asks students to take a moment to reflect on their learning experience.
   • Students are prompted to answer the following questions:
     1. What was the most important concept learned today?
     2. What questions remain unanswered?
   • The teacher collects these reflections and uses them to address any remaining confusion in the next class or modify the instruction for future classes.

Closure (2 - 4 minutes)

1. Summary of the Lesson (1 - 2 minutes):

   • The teacher summarizes the main points from the lesson, reiterating the process of photosynthesis, its components and its importance in the ecosystem.
   • The teacher emphasizes the role of plants in photosynthesis and how this process contributes to life on earth.
