ENVIRONMENTAL STUDIES Standard One Term II
37
Dear Teacher, We all know that children enjoy nature around them- the trees, the plants, the animals, the birds and the rain. This book starts with their life experiences i.e what they have seen and enjoyed. The activities are based on their own experiences, about the people and the world around them . Children may know a few songs and stories when they come to school. Quite naturally they enjoy listening stories, singing songs and playing games. So we have included
pleasant
songs, enjoyable stories, thought provoking
activities and games. Several opportunities have been provided to kindle the imagination of the children. They can make up stories, act them out, sing and dance joyfully. Children love to draw. This natural ability to draw and be creative has scope in simple line drawing, imaginative drawing and colouring activities. Every chapter has "I can" activities that provide a scope for self-evaluation. Every child has different life experiences. We need to provide time for discussions so that children share their thoughts, ideas and observations. An atmosphere conducive to raise questions must be provided in the classroom. Learning does not only take place in the classroom. Learning should be extended to the outdoors where children will learn happily. Many people help us in our daily life. If children can interact with them, it will widen their understanding and build respect for their work. Science is part of everyday life and can be understood by observation. A love and caring for nature should be inculcated in children. Authors
