Getting colourful in Science!


In Science we have been learning about how different materials can change in a variety of ways.
Last week, the Year One students took part in a hands on Science experiment called Rainbow in a bowl.




The children were very excited to start the experiment so we got to work straight away. First, we had to look at our ingredients and predict what was going to happen. Some of the children had wonderful predictions about smoke forming; colour blasting and we even had some children predict an explosion!

The ingredients in our experiment were:

- Hi lo Milk
- Food Colouring x 4 colours
- 50 ml Dishwashing liquid


After talking about our predictions, it was time to begin! We divided the class into a boys and girls table and poured the milk into a large bowl. We then put a few drops of food colouring around the plate of milk and then we were ready for the rainbow to begin!













Cooper was my Science assistant for the boys table and Zahra for the girls table. They each poured the dishwashing liquid into the milk and the colours started to mix around the bowl just like a rainbow!





We discovered that the fat in the milk was pushed to the edge of the bowl when the dishwashing liquid tried to mix in. The fat in the milk moved the colours around which made for an amazing sight.

This relates to the outcome of: Everyday materials can be physically changed in a variety of ways (ACSSU018within the Chemical Science strand of the Western Australian curriculum.

The children had a fantastic time learning about mixtures!

Have a lovely night
