The soil which is inevitable for the existence of life is being depleted in many ways Students evaluates the intensity of perishing of the soil Knowledge about process of soil formation Process of weathering Students develop attitude to identify soil perishing situations.  Chart-reasons for perishing of the soil ·         Formation of soil ·         Uses of soil  Discussion method Social science text book-VIII Social science hand book-VIII

EVALUATION/RESPONSE

You all know well about the uses of soil for human life. Which are the important uses of soil? So human beings are using soil for different purposes. Through this we lead changes in the quality of soil. Some of the human activities lead to reduce the quality of soil. Today we will discuss about perishing of soil.                            PERISHING SOIL (BBH) Soil gets depleted due to various human activities. Which are the major activities done by human which depletes soil? Yes! Deforestation, destruction of hills and unscientific agricultural activities leads to the depletion of soil. How the trees help to reduce soil erosion and depletion? Yes! The roots of trees help to reduce soil erosion by holding the soil like a net. Man is killing the soil by felling the trees and tilling the land for cultivating intensively without considering the environment. Write the methods or alternatives that help in environmental conservation.                     Students discuss in groups and finds out the points. Points are listed out in board and conclude the discussion.  Discussion points -use of degradable materials - use of agricultural land - Draining waste water in to the soil - over grazing Use of non degradable substance like plastic will cause soil pollution. Chemical fertilizers change the structure of the soil. Agricultural land should be protected.   Activity 2 Teacher shows some pictures of soil pollution. Children asked to write a note about the topic ‘soil and humans’. Students write the note and read it out in the class. Teacher concludes the discussion.                         So soli pollution is mainly due to the activities of human being. We need to protect the soil as we depend up on the soil for our needs.    Summary        Soil pollution means the change in structure, physical, chemical and biological property of soil. Polluted soil cannot be used for any Other activity. Human activities such as deforestation, destruction of hills and unscientific agricultural activities leads to the depletion of soil. Man is killing the soil by felling the trees. REVIEW QUESTIONS 1.      What is soil pollution? 2.      Which are the major activities leading to depletion of soil? 3.      How the plastics pollute the soil? 4.      How over grazing affects soil quality? FOLLOW UP ACTIVITY How the plastics influence the human life today? Write a note on plastics and soil pollution.
