About SCIENCE Class 10 CBSE Curriculum
☞ SCIENCE Class 10 CBSE :The subject of Science plays an important role in developing well-defined abilities in cognitive, affective and in addition to it, psychomotor domains in children. For instance, It augments the spirit of enquiry, creativity, objectivity and aesthetic sensibility.
Upper primary stage demands that a number of opportunities should be provided to the students to engage them with the processes of Science like observing, recording observations, drawing, tabulation, plotting graphs, etc., At this stage, while Science is still a common subject, the disciplines of Physics, Chemistry and Biology begin to emerge. The students should be exposed to experiences based on hands on activities as well as modes of reasoning that are typical of the subject. Here is the Course Structure of SCIENCE Class – 10 CBSE Annual Examinations.
