My idea for an experiment to test displacement was to gather various small objects to put in water. I want to see whether these objects will displace enough water to make them float or not.
Then I can try it out with an actual steel nail, and a stainless steel bowl (as the ship).

Why does the nail sink and the ship float?
Why does the steel nail sink? The steel nail sinks because it weighs more than what it displaces. The nail isn't very big/wide, so it isn't able to displace much water.
Why does the steel ship float? The steel ship floats because it displaces an amount of water equal to what it weighs due to it's large size and because it's wide. Ships are also made with hollow areas and are filled with air, which helps the ship have less density than water.

Bouyancy,Density,and Displacement
Bouyancy-The loss in weight an object undergoes when placed in a liquid. It determines whether an object will sink or float.
Density- An object's mass divided by it's volume. Water's density is 1.0 . If something has a greater density than that,it will sink in the water.
Displacement- When an object is placed in a liquid, it pushes some of the liquid out of the way and takes it's place. If something displaces less than what it weighs, it will sink.
