This week is Science Week and throughout the school interesting and intriguing experiments and activities are taking place.
The theme for Science Week is 'change' and in class 3 we began with a colour change. We tested different materials to see if they were an acid or an alkali using an indicator solution made from red cabbage. It was easy to see if the material was an acid as the solution turned red and if it was an alkali, it turned blue. We ended up with a range of colours, including pink and green as we tried to find out what would happen when you mixed an acid and an alkali. We also tested our materials using indicator paper strips.
