Today Room 7 learned what it was like to be scientist!
We talked about what science is and decided that science is about doing things like creating, discovering new things, designing, experiencing and making things!
Today we got to experience the Lava in a Cup experiment.
We had questions like:
Why did the oil float on the top of the water?
Why did the salt sink to the bottom?
Why did the oil bubble up to the top?
Well, here is the science behind it:
Oil floats on top of the water because it is lighter than water. The salt is heavier than oil so it sinks down into the water and takes some oil with it. However, then the salt dissolves and back up goes the oil!
Ingredients that we used today include: oil, water, food colouring (red), and salt.
