We have a lovely class set of little ripple tanks that allow them to play around and observe wave behaviour

I like this one as a predict, observe and explain exercise to hammer home force on a current in a magnetic field and Fleming’s Left Hand Rule.

Here it is going in circles, with a bit of help!

A couple of students in my enrichment group have made a nice linear motor. #iteachphysics #chatphysics

Kicking a concrete football. A nice question for getting students thinking about force and momentum carefully.

Building little motors with batteries and neodymium magnets is great fun.

The drinks can induction motor. One of my favourite demos, putting Faraday’s and Lenz’s laws together in a fairly complex situation.

To get them really thinking hard you can ask why the current trip on the supply only goes once it spinning at a good rate?

200g mass (i.e. about 2N) at each end of the string.

What tension does the Newton metre read in the middle? #chatphysics #itachphysics

The answers to why the sky is blue and why are sunsets red are both illustrated well by this demo #chatohysics #iteachphysics

This was posted by a physics teacher on another app. I don’t think they’re on here so I hope posting it isn’t seen as an attack on them. Can anyone spot my problem with the slide (and it’s not the Formby reference)? #chatphysics
