my scince fair topic is : which flour effects the density of flour the most all-purpoes flour, bleached flour, or yellow cake flour?

Your question can easily be answered by doing a search for 'density'. This will tell you that the density of a substance is its mass per unit volume. So, all you have to do is weigh equal volumes--say 1 cup--of each flour to determine the powder density of each. Just be sure to repeat the measuring of 1 cup and the weighing at least three times so you can get an average density. That will be more accurate than if you just did one measurement.

What exactly is your 'project'?
