This week we did a Science experiment: "Magic Milk". This is where milk is placed in a dish, along with spots of food colouring. Then one/ two drops of detergent are added to the mixture. What is the result?? Scroll down to find out!
Our hypothesis: The milk will either bubble when the detergent is added or it will mix together with the milk and food coloring.
Our observations: Firstly there was just a pink plate with milk on it. When we added the food colouring, it just mixed in with the milk. When we added the detergent it swirled the food colouring around in patterns and then it eventually all mixed in together with the milk and detergent.
Our conclusions: Milk contains fat molecules.These are very sensitive to any changes in the milk. When the detergent is added a chemical reaction occurs, as the soap and fat molecules work hard to join together. This is what causes the swirling motion in the milk.
At the very end of the experiment we added pieces of paper into the mixture in order to get some tie dye styled art!
ReplyDeleteits so cool
That sounds like fun!
ReplyDeleteAll the senior classes have done that experiment. I liked the different colours and patterns.
What colours did you use?
Did you get cool patterns?
