That Sinking Feeling: Density Currents Lab
Seawater density varies depending upon your location, which means that ships float higher or lower in the ocean depending upon their location as well. In a hands-on activity, individuals explore the density of ocean water. In groups,...

Density Column Lab - Part 2
Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the liquids...
