In a Class VI science lesson, the teacher is explaining the function of green leaves and the process of photosynthesis. He draws diagrams on the board, shows charts explaining chlorophyll, light and dark reactions, and finally plays a video illustrating the entire process. Students watch carefully, follow the teacher's explanations, and note down the steps of photosynthesis. The teacher's approach focuses on showing and explaining scientific phenomena rather than having students perform experiments or solve problems independently. Which teaching method is primarily used here?
