We have been studying the concept of density in relation to floating and sinking. We made a "magic column" with golden syrup, oil and water and then floated different objects in them. The layers occurred in the cup because the liquids had different densities. The golden syrup was most dense and sunk to the bottom while the oil was the least dense and floated on the top. The objects had different densities also which made them float in various parts of the cup.
In another experiment we had to make an egg hover in the middle of a cup of water. The equipment we were give was 2 eggs, fresh water, salt and 2 cups.
