This week in science, we had a go at the moving colours experiment. This is a great experiment for kids to learn about chemical reactions.
This experiment is really fun, easy and simple to set up at home with everyday items from around the house.
You will need:
|Hansen helping with step one|
Begin by pouring milk into a bowl or plate. You will need to ensure you have enough milk to cover the base of the plate. Add a few drops of food colouring to the milk, we used 3 drops each four different colours .
|Payton, with Step 2, watching the colours split|
Carefully dip your cotton bud into a drop or 2 of dishwashing liquid and place the dipped end of the bud into the middle of the milk. Quickly a chemical reaction will occur, we will see the colours begin to spread away from the dishwashing liquid drop and split in two.

Next, you can slowly stir around the outside of the bowl or plate and watch the magic happen!
Some groups decided to go a step further and add extra dishwashing liquid to the milk to see what would happen after the initial reaction. We had some great results!
