This week in science club, children got to carry out an investigation using red cabbage juice as an indicator to work out if a variety of substances were either acidic or basic. This was carried out  by observing a colour change which will indicate a reaction having taken place.
They made predictions and performed the experiment and observed whether their predictions were correct. We had the pH scale to help us with our results.
They also observed a chemical reaction were water was turned into wine/ grape fruit juice colour and then turned back into water again.
