생물 수업 시작에 학생들을 미소로 맞이하는 교사

Teacher enters the class with a smile. “Good morning, students! Today, we are not just studying Biology… we are going on a journey into the world of life!” Students look excited. One student asks, “Sir, what do you mean by world of life?” Teacher replies, “Biology is the study of living things, and it has many branches—each one like a different path in a big forest.”
