“If it wriggles, it’s biology. If it stinks, it’s chemistry. If it doesn’t work, it’s physics.”
So goes the urban myth, based upon many a classroom experience. There is a temptation when teaching physics to choose a glitzy, Brian Coxy video clip to engage and enthuse learners, over the have-we-got-the-kit, you-need-three-days-notice, haven’t-got-time-to-test-it real demonstration.
Alom Shaha has been producing some excellent video sequences designed to encourage physics teachers to choose demonstration over video in their teaching. Now, he has made a 30-minute film about how to demonstrate, drawing on the experience of magicians, and science explainers against the backdrop of a road trip across a large chunk of the USA.
Get yourself a nice glass of something wet, kick back and treat yourself to some solid encouragement. The film is here and the notes are here. You might even consider using the film and notes as a basis for a cracking and practical science department CPD session.
