The subject of Biology 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, recording observations, drawing,
tabulation, plotting graphs, etc., whereas the secondary stage
also expects abstraction and quantitative reasoning to occupy a
more central place in the teaching and learning of Biology.
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.
