We are going to see an experiment that will show us the density difference between liquids in the kitchen. The denser a liquid is, the more weight it will have in the same volume.
By doing this experiment you will be able to intuitively remember the densities of different liquids and realize how density affects the buoyancy of the bodies.
Let's take from the kitchen or supermarket:
1) Honey.
2) Soap.
3) Water.
4) Oil.
5) Alcohol.
It will be good to have food coloring to color water and alcohol. The densest liquid is the one that will weigh more and is going to deposit down the tower. The one that has a lower density, is going to be located above the tower. For the colors to be clearly defined it is important that we introduce the liquids in the container in order of density, that is:
1) Honey.
2) Soap.
3) Water.
4) Oil.
5) Alcohol.
Here you can see in video the step by step of this experiment:

DENSITY THEORY
Density is one of the most important physical factors. Density gives us the relationship between weight and volume that a body occupies. For example 1Kg of steel and 1Kg of straw weigh the same, however 1Kg of steel you will be able to put it in a small kitchen pot and for 1Kg of straw you need much more space. This tells us that the density of steel is much greater than that of straw.
In water, the density of water is also very important. The principles of Archimedes of floating bodies need density to explain themselves. The greater the greater the density, the higher the pressure will be. The large amount of salt in the Dead Sea is what makes the density higher and floats more than in the Mediterranean Sea.
