About SCIENCE Class 9 CBSE Curriculum
☞ 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. In another words science play very important role in overall development of a child. It augments the spirit of enquiry, creativity, objectivity and aesthetic sensibility.
Therefore, the upper primary stage demands that a number of opportunities should be provided to the students to engage them with the processes of Science for example 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 Science. Thus, the idea of atoms and molecules being the building blocks of matter makes its appearance, as does Newton’s law of gravitation.
