Introduction

 

 

 

Science is a dynamic, expanding body of knowledge. It involves observing, exploring, hypothising, verifying, analyzing and interpreting various phenomena occurring around us. It is common knowledge that except few, hardly does any Science teacher encourages a student to go beyond the content and concepts given in the textbook. This is making the subject boring and dull.

 

 

Science can be made lively and interesting by giving students hands on experiences and by encouraging them to ask questions, observe, explore, experiment and investigate. Learning should not remain confined to the classroom alone but it should be intricately woven into the experience of the daily lives of the students. This document "Learning by Doing" for class VIII is aimed at meeting some of these aspirations and expectations of the subject.

 

 

The activities included in this document are based on the content/concepts given in NCERT textbook in Science for class VIII. Effort has been made to keep the activities very simple easy to perform with  minimum cost involvement. The activities are of different types involving observation, exploration, experimentation, investigation. Some of the activities are in the form of riddles, games and puzzles.

 

 

It is hoped that students and teachers will use this book in the right spirit and pave the way for better teaching-learning process in Science.
