Litmus Paper Experiments

Primarily aimed at the upper end of KS2 but I have used this with Year 4 and Year 7 as all files can be modified to suit different ages and abilities.
The files support the practical teaching of using litmus paper to determine acid, neutral or alkaline properties.
There are a number of worksheet options depending on how you would like to approach the lesson, a powerpoint presentation with plenary slides to assess understanding and a loop card game, either to be played as a class, group or individually matched.
