In-Class Activities: (15 - 20 minutes)

1. Photosynthesis Role-Play (8 - 10 minutes): To better understand the process of photosynthesis, students will be divided into groups of five. Each group will be assigned roles - 3 students as sun's rays, 1 as a plant, and 1 as a scientist who will take notes and observe the process. The "sun's rays" will stand in a semicircle around the "plant." The "plant" will have cut-out chloroplasts and glucose to show the process of light energy conversion. The "sun's rays" will shine a flashlight on the "plant," and the "plant" will convert the light energy into glucose. The "scientist" will take notes on the process. This role-play will help demonstrate the concept of photosynthesis in an interactive and enjoyable way.

2. Cycling of Matter Card Game (7 - 10 minutes): After understanding photosynthesis, students will now learn how it plays a crucial role in the cycling of matter. The teacher will provide each group with a set of cards representing different elements and compounds involved in the cycling of matter, such as sunlight, carbon dioxide, oxygen, glucose, water, and decomposers. Students will take turns playing cards and explaining how the element or compound impacts the cycling of matter and the role of photosynthesis in the process. This game will make learning fun, engaging, and competitive.

3. Round Table Discussion (5 - 7 minutes): To wrap up the lesson, students will participate in a round table discussion. Each group will have a chance to share their thoughts, insights, and understanding of the topic. They will discuss the process of photosynthesis, its role in the cycling of matter, and its significance in the environment. The teacher will facilitate the discussion, clarify any misconceptions, and provide feedback. This discussion will help students learn from each other and deepen their understanding of the topic.
