CBSE CLASS 10 SCIENCE TERM-2 SYLLABUS 2021-2022

SCIENCE

(SUBJECT CODE – 086)

SYLLABUS FOR PURPOSE OF EXAMINATION 2021-22

CLASS – X

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, analyzing and driving conclusions etc., whereas the second 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 been taken to avoid the temptation of adding too many concepts that 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 I+II) will be 80 marks and 20 marks weightage shall be for Internal Assessment (Term I+II).
  2. Internal Assessment – Maximum Marks 10 for each Term:
  • There will be a Periodic Assessment that would include:
  • Three periodic tests will be conducted by the school in the entire session. The average of the two periodic tests/marks of the best periodic Test conducted in the Term is to be taken into 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.
  • . Subject Enrichment in the form of Practical/Laboratory work should be done throughout the year and the student should maintain a record of the same. Practical Assessment should be Page 2 of 10 continuous. All practicals listed in the syllabus must be completed.
  • Portfolio to be prepared by the student- This would include classwork and other samples of student work.
