For the final week we sorted liquids by pH although we didn't actually use that phrase.
We chatted about acids and alkalis around the home - most of the children knew the word acid and were aware of things like lemon juice and vinegar. We had a closer look at citric acid in sherbet and other sweets.......tarty!
I had made a batch of red cabbage indicator ( a good time of year for red cabbage!) and I soaked some art paper in it to make indicator strips.
We demonstrated what the red cabbage indicator liquid did in acids, neutral and alkali then everyone had a go testing our 6 liquids.
We then had a look at a rainbow of colours given by universal indicator liquid before testing our liquids using paper strips.
Finally we chose our best alkali and used turmeric paper strips to give a deep red.
So our time at Brynteg has finished. We've had a brilliant time and the feedback from staff and pupils has been incredibly positive.
Even more exciting is that Reaching Wider Partnerships has more funding so we will be able to deliver this project to more schools in NEWales.
