Foreword Foreword
Science is being taught is school in a very mechanical way. Students are confined to their textbooks, the 
topics and contents included therein. They are hardly encouraged to observe, explore, look for 
patterns or analyse the everyday experience occurring around them. Mere rote memorization of 
concepts is leading children towards a stressful existence. NCF 2005 aptly says, "The fact that learning 
has become a source of burden and stress on children and their parents is an evidence of a deep 
distortion in educational aims and quality". To correct this, the NCF has proposed five guiding 
principles. Some of these are;
i) connecting knowledge to life outside school
ii) ensuring that learning shifts away from rote methods.
The present document "Learning by doing" is an effort by the Board to make Science learing more 
meaningful, interesting and joyful. This document is in continuity to our earlier documents for classes 
VI and VII brought out in preceding years. An effort has been made to include activities which are based 
on different content areas and concepts given in NCERT textbook in Science for class VIII. It is hoped 
that after performing these activities, students will be able to understand the concepts better, 
internalize them and will be motivated to create more such experiences. Wide variety of activities 
including observation, exploration, analysis, games, riddles, crossword puzzles etc. have been included 
to meet diverse needs of learners and help them appreciate and enjoy the learning experiences. The 
suggested activities have been so designed that they can be done easily without using expensive 
materials or equipment.
I take this opportunity to put on record my sincere and heartfelt thanks to all the members of the 
development and editorial team for sparing their valuable time and extending their expertise in 
finalization of this document. My deep appreciation and thanks are due to Smt. C. Gurumurthy, 
Director (Acad.), CBSE for providing guidelines and directions at different stages of preparation of this 
document. Dr. (Mrs.) Srijata Das, Education Officer, CBSE deserves special mention and appreciation 
for putting in her honest efforts in perceiving, coordinating and completing the documents in time.
It is hoped that all the schools and Science teachers would use this document in right spirit and 
encourage the students to perform these activities and learn by doing rather than rote memorization.
In its endeavour for continuous improvement the Board welcomes observations, comments and 
suggestions from the users.
