text: how do i graph egg flotation results? my science project invovled eggs floating. now i know why but how do i graoh my data. should i graph it on amount of salt used.. or how much it flaots or what!?!??!?!? if each container contains exactly the same amount of water, you could use the amount of salt that you place in each container.  however, if you have a way of measuring the specific gravity, such as a hydrometer, graphing by specific gravity would be a better way of doing it.
