Density tower experiment
Today we work with different liquids:
Dish soap, water, condensed milk, sunflower oil, body oil and a grape.
We talk about what is going to happen when we pour them in a glass...
Some pupils say they will mix. Some pupils say they will stay separate.
Then they predict which one will stay at the bottom and which one on top.
This is what happened...
After that we watch a video to see what happens with other liquids.
MORE DENSE LIQUIDS STAY AT THE BOTTOM,
LESS DENSE LIQUIDS FLOAT.
Each layer is less dense than the one below it.
