Foreword
Education is the number one priority of the Ladakh Autonomous Hill Development Coun-
cil—Leh (LAHDC), and one of the first steps in this direction is to make available to the
students locally relevant textbooks which please as well as they teach.
Science is better understood by observation and more so when children can relate their own
surroundings and environment to what they read in their textbooks.
The science textbook for the 5th class is ready and I have gone through it. The book is simply
written, clear, comprehensive, interesting, and most of all it is Ladakh- appropriate. Each
chapter has been developed as a self-contained unit of study that may be used in any sequence
the instructor wishes. Numerous illustrations have been introduced wherever necessary. This
I feel will make students thoughtful viewers; at the same time it teaches them to be thought-
ful readers.
The team of dedicated teachers from Education Department LAHDC, Leh and SECMOL have
developed this book in collaboration with the Jammu and Kashmir State Board of School
Education. The Ladakh Autonomous Hill Development Council, Leh has actively supported
it from the very beginning.
I am sure this book will find an encouraging response from the children, parents, and teachers.
I would like to thank the teachers, SECMOL, J&K Board and all other people involved in
the development of this book.
