(Code No. 086 / 090)
The subject of science plays an important role in developing in children well-defined abilities in cognitive,
affective and psychomotor domains. It augments the spirit of enquiry, creativity, objectivity and asthetic sensibility.
Whereas the upper primary stage demands that plentiful opportunities should be provided to the students to engage
them with the processes of science like observing, recording observations, drawing, tabulation, plotting graphs etc.,
the secondary stage 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 six 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 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 as well as modes of reasoning that are typical of the subject.
