Milk Experiment

Last week, Room 12 did an experiment using milk, food colouring and dishwashing liquid. Some children have written explanations about it.

The Milk Explosion Experiment !!! - Melvina

How to do the 'Milk Explosion Experiment'

Firstly, you need ingredients and those ingredients are: milk, food colouring, ( red ,blue, yellow and green), bowl, dish washing liquid and a cotton bud. The food colouring you choose are optional but only four colours. Next, you put the food colouring but you need to put them seperately or the experiment won't work. Then, you get your cotton bud and with one side put dish washing liquid on to it and then carefully put the cotton bud in to the middle and watch what happens.

It all mixes together and twirls around. This happens because of the milks fat and protein. They keep bumping together to find molecules. Scientists have an example of telling about fats and proteins, so you can get the idea of what they are trying to say. Scientists say, that when are at a disco you find a new friend to dance with, so that is what happens to the molecules. The fat and protein molecules are dancing around. This is a physical change because it can not change back to how it was before.

Thats how we make Swirling Milk.

Burst of colours

How do you make milk colourful?

Firstly,you get a bowl or a dish and put in some milk about halfway. Next, you add some food colouring green,blue,yellow,and red. Only put one drop of each colour. After that,you put dish washing liquid into the bowl and watch it burst out with colours.

What is happening is a physical change because it is still milk and it is still food colouring even though they are moving around. Milk has fat and protien. When the fat and protien bump together they find molecules.

You might even want to try this fun science experiment at home. Give it a try. You can tell your friends, auntys, cousins and uncles. Watch the teriffic, magnifient sight inside the bowl. 'What a delightful thing you have made' thats what your Mum or Dad might say.

Colour Disco!!!

Do you know how to make all the colours explode? The ingredients are dishwashing liquid, a bowl, food colouring and a cotton bud. Firstly, you put in milk and then you put in the food colouring into the milk. Then, put in the dishwashing liquid. Then you will see the reaction starting. The reaction is starting because of the soap molecules are bouncing off each other to find fat from the milk. I liked it because I saw a rainbow in a bowl.
