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 (ACSSU018) within the Chemical Science strand of the
Western Australian curriculum.
The children had a fantastic time learning
about mixtures!
Have a lovely night
