SCIENCE, (Subject Code - 086), Syllabus for Purpose of Examination 2021-22, CLASS — IX and X (2021-22), , The subject of Science plays an important role in developing well-defined abilities in cognitive,, affective and psychomotor domains in children. 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, hypothesizing, experimenting recording, observations, drawing, tabulation, plotting graphs, analyze and drive conclusions etc., whereas the, secondary stage also expects abstraction and quantitative reasoning to occupy a more central place in, the teaching and learning of Science. Thus, the idea of atoms and molecules being the building blocks, of matter makes its appearance, as does Newton's law of gravitation, , The present syllabus has been designed around seven broad themes viz. Food; Materials; The World of, the Living: How Things Work; Moving Things. People and Ideas; Natural Phenomenon and Natural, Resources, Special care has heen taken to avoid the temptation of adding too many concepts than can, be comfortably learnt in the given time frame. No attempt has been made to be comprehensive., , 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., , General Instructions:, 1. The total Theory Examinations (Term 1) ID) will be of 80 marks and 20 marks weightage shall, be for Internal Assessment (Term [+II)., 2. Internal Assessment - Maximum Marks 10 for cach Term:, a There will be Periodic Assessment that would include:, , e Three periodic tests will be conducted by the school in the entire session, Average of the, two periodic tests/marks of best periodic Test conducted in the Term is to be taken for, consideration., , © Diverse methods of assessment as per the need of the class dynamics and curriculum, transaction. These may include - short tests, oral test, quiz, concept maps, projects,, posters, presentations, enquiry based scientific investigations etc., , b Subject Enrichment in the form of Practical/I.aboratory work should be done throughout the, , year and the student should maintain record of the sare. Practical Assessment should be, , Page 1 of 10
