This morning we did a science experiment for Science Week. For this experiment we needed food colouring, cotton wool, full fat milk, washing up liquid and some shallow plates. We had to pour the milk into the plates and let it settle. Then we poured the food colouring into the milk. We had yellow and red food colouring. The food colouring settled on top of the milk. Then we got the cotton wool and dipped it into the washing up liquid. We then held the cotton wool steady in the milk and it broke the chemical bond holding the fat in the milk together. Then the food colouring spread out into the milk and made lovely pictures and patterns. It was great fun.
