Declan Fleming presents some simple pH demonstrations

I always ask my outgoing sixth formers what activities they found the most memorable from their time at school. Almost without fail, ‘rainbow fizz’ is mentioned – an introductory acid–base practical that gives students a look at indicators and neutralisation. This got me thinking – if it’s so memorable, is it worth repeating for older students?

With attached powerpoint slides and an accompanying video Declan Fleming presents two simple pH demonstrations, from preparation to presentation, and discusses how best to use these to support learning.
