Evaluation for the concept (for the teacher)

The students have to be introduced to different cycles and their dynamics. It becomes important to take into account various factors which affect the working of these cycles. Also to keep the students glued to the topic we must keep it as real as possible. Many day to day current affairs and disasters are connected to these cycles. Care should be taken so that children understand the basic concepts of these cycles and their value the environment and to the human life.
