A knotty problem

How does the length of a piece of string or rope vary with the number of knots tied in it? I came across this question a few months ago and decided to try it out as an investigative activity to help A-level Physics students revise some basic practical skills. I’ve since seen other Physics teachers, like Frank Noschese, tweet about using it in class. What’s the relationship between the number of knots and the length of the rope? Great #modphys graphing lab I learned from @hbarphysics! — Frank Noschese… Read more A knotty problem

Why I returned to teaching

I know I will cry when I eventually leave the school where I’ve worked for the last decade or so. I won’t be able to help it – I’ve cried on my final day at every school I’ve ever belonged, as a student or teacher. The last time was when I left my second teaching job, in the belief that I was leaving the profession for good. I had been studying part-time for a masters in Science Communication and this had led to an offer of a job as a… Read more Why I returned to teaching

Looking more closely at the world

It’s been a while since The Young Atheist’s Handbook was published but I’ve continued writing about Atheism and Humanism in New Humanist magazine and elsewhere and I have become a trustee of the British Humanist Association. However, I’ve been focussing on my work in science education and am proud to announce that Demo: The Movie, a film about how and why we should use demonstrations in science teaching, is now available to view. It’s very much a film for science teachers and it looks at how we can get our… Read more Looking more closely at the world

The Use of Demonstrations in Science Teaching

A couple of weeks ago, I took part in a live recording of the Guardian’s Science Weekly podcast which was also filmed for the Royal Institution’s Ri Channel. My friend and former teacher Dr Michael de Podesta has written a kind of review of the podcast which prompted me to put up this blog post in which I want to share some notes I made on doing science demonstrations as part of my work as a Nuffield Education Fellow last year: Demonstrations, like whole class practicals, are an “activity which… Read more The Use of Demonstrations in Science Teaching
