Environmental Studies or EVS is? the study of the environment in the context of earth and living things. It is more concerned with the scientific attitude to explore, investigate, and develop an understanding of our natural, human, social and cultural dimensions of local and wider environments.At the primary level, children must be taught through an integrated approach rather than teaching in parts to develop their understanding as a whole i.e., their ability to relate the topic with each other and to understand every part of it.Teaching Class IV "Scarcity of water" While teaching the topic "Scarcity of water", the teacher should tell the children its causes and effects along with the things which can be done at their level to prevent or spread awareness about it.It is very important for a teacher to use daily life concrete examples to make the children understand the adversity of it and to make them concerned about their environment and its resources.To assess any individual on any given topic, one needs to assess the solutions that the individual can suggest to tackle with the problem. For example, a primary teacher effectively assesses the students of class IV on the topic of œScarcity of water by finding out how they have started saving water in their day-to-day life.When the students will tell their ways of saving water in their day-to-day life it will serve as conclusive criteria to assess the students on the topic of the scarcity of water.HintConducting a written test on a topic, organizing poster-making activities and asking children to write slogans on the conservation of water will not help the teacher to assess the children's understanding of the topic in practicality.Therefore, the teacher can assess children of class IV on the topic of "Scarcity of water" by finding out how they have started saving water in their day-to-day life.
