__Learning Objective__ To investigate the effect of food colouring and detergent on milk and water. __What did we use?__ *Milk *Water *Food Colouring *Plastic Bowl *Detergent *Cotton Bud __What did we do?__ In science, Ashley and Vanessa brought some milk, water, food colouring ( green, red , yellow and blue ), plastic bowls, detergent and cotton buds. Firstly, Ashley got a bowl full of water and a few kids put food colouring in it. Then Kaltum got a cotton bud, which had been dipped in detergent and put it in the water. __THE EFFECT:__ When the cotton bud touched the food colouring it separated a little. Then we all paired up and were given a bowl of milk. Then Ashley and Vanessa put food colouring in the milk. After that we all received a cotton bud and we dipped it in some detergent. Then we put it in the milk. __THE EFFECT:__ The food colouring tried to get away from the cotton bud and the detergent. It separated.

__Conclusion__ The detergent was attracted to the fat in the milk so all the food colouring went away. But in the water there was no fat so only the food colouring around it separated. By Arshiya Grade 5/6
