Density

Recently, students participated in a few science labs to better understand density. One such lab had students test four different colored liquids for their density. The goal was to organize the four liquids in order from least dense to most dense. In order to figure this out, teams of scientists layered small amounts of the liquids in straw using a pipette. If the colors mixed, the one on top was more dense. If the colors didn't mix and one stayed on top of the other, the one on top was less dense. After about 20 minutes every scientific team had successfully layered all four liquids in the straw.
