Bulwell Academy - Science - Acidity Testing

During our third visit to Bulwell Academy's Science Department, Class 5 took part in acidity tests. We learnt that different chemicals and materials have different levels of acidity from acid to alkali. To do this we used ground up red cabbage to act as a natural litmus paper indicator. We then tested different household chemicals e.g. Daz, vinegar or washing up liquid, to see if they were acid or alkali. here are some photos of our experiments.
