Our topic this term is "Sharing our Stories" and learning how these stories have changed over time.
As part of this topic, we are learning all about change. We will be learning what is change, and what makes things change. We are beginning by observing some very simple science experiments that show how things change.
(Thanks to Mrs Douglas from Room 4 for sharing her experiment information with us).
Swirling Whirling Milk Patterns
For this experiment you will need
Whole milk at room temperature
Food colouring
Dish wash Detergent
A shallow dish
We poured some whole milk into a shallow dish
Next we added a few drops of food colouring into the milk
Then we added in a drop of dish wash detergent
What Happened!
The fat in the milk is broken down by the detergent. This caused the food colouring to swirl and whirl and make amazing patterns. It was like looking through a kaleidoscope.
Wow!
This looks fun. I am going to try it at home. can you use any kind of milk?
ReplyDeleteYou have to use whole milk with fat in it. It doesn't work if you use trim milk. Also the milk has to be at room temperature so it works best if you put the milk in the pan and leave it for a little while.
