The geometers of ancient Greece invented a peculiar game for themselves, a game called Construction, whose objective is to draw various geometric figures of interest. We are permitted to use just two instruments: an unmarked straightedge (a ‘ruler’), and a compass. Using these, we can draw a straight line through any given pair of points, and we can draw a circle with any given point as centre and passing through any other given point. (Oh yes, we also possess a pencil and an eraser, please do not feel worried about that!)

A curious 11-year old boy walks up to his teacher to ask, “What is a flame? What’s going on in there?” After a brief pause, the teacher replies, “Oxidation”. Factually speaking, the teacher was right on point, but the student felt deflated, wondering if there’s more to explaining the science behind something other than giving it a different name! The kid in this story grew up to be the famed Hollywood actor and director, Alan Alda.
The microscope is the mainstay of cutting edge research in many fields of biology today. When was it invented? What did the initial versions look like? What are some of the latest versions, and what can we use them for? This article provides glimpses into the history of microscopes before recounting some of its more recent and exciting developments.
 
Richard Fernandes co-founded Centre for Learning (CFL), Bangalore - an ‘alternative’ school, where he developed and implemented laboratory-based curricula for learning Physics. A strong believer in the dictum that “Physics is best learnt by doing”, he enjoys building experimental apparatus from material found in scrap yards or cannibalized from discarded instruments. In this interview, he shares his experiences of being a Physics teacher at the middle and high school.

As a teacher educator, I begin my class with a classroom experience, though my undergraduate students, learning to be teachers, find it ridiculous at first to participate in a set of concentration exercises. This is what I tell them:

This article explores the role of beauty in science education. The authors use research in science education to highlight the importance of teachers consciously making connections to aesthetic aspects in science. Caring about beauty in science can inspire a sense of wonder and curiosity among students.
 
Horses and rainbows make the world seem more exciting, not science”– student quoted in Mark Girod’s dissertation research study
Our Sun is visible during school hours, as long as the sky is relatively cloudless. Equipment that we can easily construct ourselves can be used to conduct simple observations and make measurements related to the Sun, from which insights into the world of astronomy, the workings of the Sun, pin-hole cameras and imaging, can emerge. A few examples of these activities are described here, with pointers to external text and video resources.
