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! pic.twitter.com/jPlA1xdp1o — Frank Noschese… Read more A knotty problem

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
