Hands on Science

We are bequeathed a legacy of clever and painstaking experiments by the pioneers of modern science. In the age of information overload, it is prudent to consider why we need to dirty our hands doing experiments, instead of merely  depending on processed information to push the frontiers of science.
 
Animals constantly interact with their environment for the most vital of functions - finding food, avoiding predators or courting a prospective mate. What role does our nervous system play in these interactions? What do we know about this vital organ system and how it is made?

Why can’t you make pots with garden soil? Are you doomed to have straight hair all your life? What is artificial silk? Find out the answers here.

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.
 
Are all that children surmise from their day-to-day experiences, actual scientific truth? In this article, we discuss three  examples that show how children have such 'prior mental models' before they enter classrooms, and how these could persist, even into adulthood. We also discuss potential ways to help learners replace these 'prior mental models' with correct scientific models.
 
Introduction
The phenomenon of colour is explained fragmentarily in chemistry, biology and physics in schools. In this article, a case is made for teaching colour as a separate interdisciplinary unit in the middle school.

Children aren’t empty vessels. They come to class with amusing, surprising and deep-rooted ideas, inconsistent with contemporary science. It is imperative for a teacher to recognise this and initiate a process of change as such ideas could hamper learning.

The emphasis in the books is on the process of science - observing, asking questions, trying to find the answers through further observations and experiments - rather than on information that chil- dren are expected to memorize without any real understanding. Needless to add, it would be difficult to use this book meaningfully without doing the activities.
