A quick lesson plenary with a couple of on-screen questions about F=ma, in an “underline the correct answer” format. The first slide is the questions only, you could give that to students either on paper or electronically, the second slide animates the answers once they’ve had a go.

This is pretty much an whole lesson, but you’ll need to insert your own half life calculations worksheet (I have one that I like, but i didn’t write it so can’t include it here). The lesson centres around eating chocolate M&Ms. Or Skittles if you prefer or if anyone in the room has a peanut allergy. The idea is to have something that gives you ‘heads’ or ‘tails’ when tipped out onto the desk.

Introduction to SHC, with sample calculations & a quick practical with a kettle.

Use a simple pendulum and a known value of g to measure Pi. A puzzle for KS5 students, presented as ‘confirm that our region of spacetime can be considered locally flat’. Let them wonder for a bit, then tell them they’ll be given a lump of metal, a ruler, stopwatch and a bit of string, and see where the discussion takes you. Opportunity to really go for those uncertainties - if you don’t get a result that you can believe in to 3 or 4 sig figs then you haven’t really tried! Original idea from Matt Parker https://twitter.com/standupmaths who has an unhealthy fascination with Pi.

Remove the turntable from the microwave oven, place a large bar of chocolate in there (maybe raise it a bit on a plastic plate). Run the microwave oven, with luck and skill you can get melted chocolate spots at the antinodes. Measure the distance between the spots, double it and you have the wavelength. Look up the frequency on the back of the microwave oven, use the wave equation and calculate c. Then eat the chocolate.

Get students talking about refraction.

A short powerpoint to introduce the idea of rms speeds of molecules and rms potential difference.

Nice illustration of Fleming’s left-hand rule. Welcome to the home of hi-fi! Come to think of it, this setup would probably also work as a microphone connected to a CRO if you yelled at it close-up. Must try it sometime.

How to choose the correct fuse for an appliance, and what happens if you get it wrong.

Intro powerpoint , and a worksheet where students use a=(v-u)/t and v^2 =u^2 + 2as in calculations.
