This booklet lists a few innovative experiments for learning science. Many of them I learnt from interesting children, people and books. The English title of this book LITTLE SCIENCE has been taken from the magazine SCIENCE AGE where most of these articles first appeared.

This book is full of DIY pumps you can make from trash or everyday materials...

Every little child does it
Making things from odds and bit
The whole world is a garbage pit
Collect some junk and make a kit.

You'll never be at a loss
Make do what you come across
Con - rod, piston, suction port
All these parts you don't import.

An attempt has been made in the book to show how some of modern junk (like tetra packs) can be recycled into joyous toys.

This booklet attempts to give a glimpse of some of the experiments and toys designed as part of the Hoshangabad Science Teaching Programme. Intensive use is made of things which are commonly available and with which the children are familiar. Many of the experiments were designed, often with the help of village children and teachers, in response to the dismal poverty existing in most village school.

Sting Games provides step-by-step instructions with illustrations for making diverse and interesting string figures. The fun-filled figures created by using strings of all sorts not only augment memory and imagination of young children but also enrich their hand-eye coordination.

Ten Little Fingers is a collation of innovative toys and science activities which the author has tried and tested in more than one thousand schools over the past twenty years. With detailed illustrations, each activity is clearly depicted. Children do not need fancy laboratories and expensive equipment for doing science activities. There is much, which can be done using throwaway things found at home. Only when children use ordinary things do they realise the relevance of science in everyday life.

Serious teachers have always raised such questions. These are legitimate concerns. With paucity of funds and poor infrastructure - how does one do justice to activity based science? There is enough evidence the world over to show that readymade kits gather dust. The models the children and teachers make themselves remain more enduring. There are amazing possibilities of doing creative science using simple, readily available materials.

Inspired teachers don’t get bogged down by rules and regulations. The weighty state curriculum does not cow them down. Instead, they carve out a special niche for themselves. They have faith in the resources and resilience of children. The limitation of the chalk-and-talk method are well known. They know that “activities” constitute great learning and children love them. They involve children as partners in organizing activities. They inspire children to recycle, reuse, reinvent waste into joyous toys and simple science models.

Does the Sun rise from and set at the same position every day? What does its rising and setting position have to do with the length of our days and nights? If we were to pick one of the stars we see in the night sky, and look at it every day, for a year, would it look like it never moved? How do we introduce young students to such mysteries of space and time, inside the four walls of our classroom?
Generating energy from eco-friendly renewable resources has become an imperative for the long-term sustenance of our planet. How did Costa Rica, a small Central American nation become the first to achieve 100% energy production from renewable sources? What are the advantages and disadvantages of different kinds of energy sources? This article examines Costa Rica’s achievement in the context of the current energy scenario in the world and also explores factors that might aid or hinder the development of renewable energy resources.
