PREFACE
This Manual of Secondary Science Kit for Classes IX and X not
only describes the kit items and their uses, but also details the
activities based on NCERT IX and X science textbooks. Moreover,
the experiments prescribed for Classes IX and X practicals by
CBSE can also be done using this kit. Thus, the Science Kit serves
as a portable laboratory whereas the manual supplements the
science textbooks.
The activities in the manual are structured in a manner so
that the students can question, explore and finally discover the
concepts involved. The manual is based on an approach wherein
attempts are made to inculcate the scientific enquiry and
understanding of the subject matter among the students. The
success and usefulness of the kit with manual will depend on
how best the teachers can motivate the students to use the items
rather than a mere demonstration by them.
Such an activity based approach has been followed in
preparation of the science textbooks in the NCERT and which
requires that the students themselves do the different activities.
In the process of doing the activities using the present science
kit not only will the students feel the excitement, but it will also
give them opportunities to think and explore and which may not
be achievable by a reading of the textbooks alone. Of course,
this requires time and keen interest on the part of the teachers.
It is hoped that the teachers would also enjoy making use of the
kit and the manual.
One of the significant reforms in chemistry laboratory
practices has been the adoption of microscale technique
throughout the world. This technique not only cuts the cost of
the chemicals and apparatuses to a considerable extent, but
also is safe and environment friendly. The various activities in
chemistry are described using the items of the kit based on the
microscaller approach.
The NCERT appreciates the hand work done by the experts,
teachers, Workshop technical staff, Publication Department staff
in the development of the kit and the manual. Special thanks are
