Liquid Layer’s 👩‍🔬 👨‍🔬

Today in the discovery room, we found some interesting new books about science, and even found some experiments we wanted to put into practice.

 

“Look, it’s a big spaceship!!”

The children chose their favourite experience from the book and have loved experimenting with different liquids.  We explored how they can change when mixed together, and what happens to the different layers. We used very basic ingredients, and got to mixing! The children liked predicting what they thought might happen…

“Is it going to explode like a volcano?”

“Maybe it will fizz up!”

We simply mixed water with food colouring, oil and golden syrup to create our magic mixture. The children suggested we all tried adding it in different orders to see if the outcome would be any different. We were really interested to see that no matter what order we mixed our ingredients, it turned out exactly the same every time!

“It’s because the syrup is the heaviest!”

“The oil is floating to the top. Look at the bubbles, it’s like a lava lamp!”

“Bubbles!!”

As the syrup is much more dense than the other liquids, it sunk to the bottom each time, and the oil floated all the way to the top. We even put all our mixtures into one big jug to see what would happen, and it turned back into 3 perfect layers!

Well done everybody! Let’s get our thinking caps on for our next experiment 👩‍🔬 👨‍🔬
