Science Experiment

Today we did a science experiment for writing. We were writing a recount so we had to follow exactly what to do so we could write in the order of when we did it and what happens. To do this we needed milk, dishwashing Liquid and different colour dye.
We also needed a white bowl, jug and a cotton bud.
First, we put milk in the bowl and then we put a drop of yellow, blue, red and green dye in the milk. We dipped our cotton bud into some dishwashing Liquid and then we very gently put the cotton bud into the centre of the bowl and waited. We watched the colours dance around the bowl it was very mesmerizing and beautiful. We later learned that the dishwashing liquid causes the fat and the water in the milk to separate and spread apart, the result was a movement of colours dancing.
