Tell the students about the four seasons (spring, summer, fall, winter). Then begin to tell them why we have the four seasons (the causes of them). For example, we have the four seasons because of the tilt in the earth and the rotation of the axis. Read a book to the students about the four seasons. After reading the book get students to think about the lesson by asking questions about the book. Tell them characteristics in each season (weather, dates the seasons start and end etc.)
