Teacher Development

Understanding nature of science is, now, widely perceived to be a vital learning outcome of science education. In this article, we briefly discuss the rationale for introducing ‘nature of science’ in school science curricula, its evolving perspectives, and the approaches we may adopt to enable the learning of this topic.

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.
 
Growing sufficient quantities of the various crops needed to feed an everincreasing population is a challenge faced by many countries - particularly, developing and under-developed countries. The availability of fertile land, suitable climatic conditions, and good agricultural practices; combined with a variety of inputs such as high yielding seeds, fertilizers, pest control agents, irrigation etc., play vital roles in this respect.
What role does electricity play in the functioning of the human body? While electricity is mainly explored as a topic in Physics in school science, and touched upon in Chemistry, is it also important to touch upon the importance of electricity in Biology, and specifically in sustaining life? This article examines the criticality of electricity in the functioning of various processes in the human body.
 
Most human understanding of motion is relatively recent – whether it’s the movement of the Earth, the expansion of the Universe, the perpetual motion of atoms or the mechanisms of movement in life forms. Integrating our understanding from various disciplines is crucial for a holistic approach to this phenomenon. This article suggests studying the causality of movement through various disciplines as a unifying theme between them.

Why is our search for extra-terrestrial life forms linked to a search for water? Why does ice float in a glass of water? What makes water different from other liquids? In this article, the author uses many everyday observations of water to explore it as a topic that can be studied across classes and disciplines.
