The ballast tank fills up with sea water when the submarine needs to be submerged. The book gives a cursory definition of density and then goes on to provide multiple examples of things that sink – because they are more dense than water – or float – because they are less dense than water. A hot air balloon is just like those you ride in amusement parks. By now you may have deduced that the method of finding density is mass over volume. Then, we arrange them in the correct, ascending order. What We Need: A pumpkin, some pumpkin carving tools, and a big tub of water This is called the ‘Archimedes Principle’. Pls.
