Working With Solutions

The 5th grade students have been investigating the relationship between salt-solution concentration and density.  Students worked with four salt solutions, each dyed a different color. Working with partners, they attempted to layer all four solutions in a clear drinking straw.  This required them to discover the successive densities of the four solutions, as well as the succession of concentration. There efforts resulted in a colorful display as they discovered that the more concentrated the salt solution, the more dense it is.
