Question: There is a brick of gold and a brick of iron in a boat (both 10 inch blocks), if they are both dropped into the water which will make the water level higher?
Hint: Gold weights more than iron.
Answer: The iron block.
The iron will make the water level higher because both blocks will actually make the water level drop most likely. In the boat they have a larger effect on the water level (raise the water level) and then when they are dropped into the water the lighter one (iron), will make the water level drop less because it is lighter and has less effect on the water from the boat but displaces the same amount of water as the gold when dropped into the water.
