In simple words, “Science” is the study of nature. It explains the infinite phenomenon happening in and around us covering micro scale to macro scale, from cell to cosmos. Thus, science is an inseparable part of everyone’s life. Advancement in science reflects in the outburst of advanced technology, which apparently makes our everyday life easier and a lot more smoother.
Assam Board Class 9 Science syllabus is prescribed by the Board of Secondary Education Assam commonly known as SEBA. The board incorporates of subject professionals who design the syllabus and revise it on regular intervals. This continuous process has brought significant changes over the years. SEBA moved a step ahead by imposing Science Practicals for Class 9. As a consequence of this extra dimension in the curriculum, science learning has become more engaging among students. Thus, this autonomous body succeeded in achieving substantial progress by attaining greater scientific and technological literacy.
Assam Board (SEBA) Class 9 Science syllabus comprises of theory as well as practical. concepts covered under theory are – states of matter, atoms, molecules and their structures, cells, tissues, living organisms, motion force, laws of motion, work and energy, gravitation, sound etc. Science practical are designed in a way that concreats the concepts they study in theory part.
