The future of coding is set in stone. According to Forbes, coding will be even more relevant in 2025 than it is now. What is it about coding that makes it such an important skill to learn and demanded in so many industries?

Just like how English is the global business language, coding is the language of technology. As we approach the peak of artificial intelligence (AI), teaching kids to code becomes a crucial part of their education.

This book is a collation of some interesting activities - geometry by paper folding, toys, tangrams, pumps, caps, experiments, and simple science models. These activities are interspersed with inspiring stories on education, peace, environment and mathematics. More than one thousand line drawings illustrate the text. This book follows no strict order or hierarchy. It is not meant for any specific age group, nor does it supplement or complement textbooks. This book shows possibilities of doing science with simple things.

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.
 

 What makes flies different from a dragonfly or a butterfly? How do the lovely iridescent bluebottle and greenbottle flies help solve murders? What do insect bites, galls and chocolate have in common? Do flies have taste-buds? How do we introduce flies in science classrooms? This article explores the fascinating world of true flies, their incredible variety, and the diversity of services they provide us with, ending with an activity that teachers can use to unravel one aspect of the life of flies to students.

How did bad weather and a chance observation of what was most likely a failed experiment, lead to the Nobel-prize winning discovery of radioactivity? In this article, the author narrates the story of Henri Becquerel’s experiments with uranium salts, describing a series of scientific investigations that arose to understand an unexpected and unusual observation, originally made by this physicist.
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
Who were the first people to think of the concept of atomic weights? How were atomic weights of elements first calculated? In this article, the authors explore the long scientific journey from the origins of the widely used conceptual framework of atomic weights to the debates on the topic prevalent even today.
