Title: Density Detective
Description: In this lesson students will learn about density and will play detective to see how this physical property can be used to identify an unknown liquid. Students will be assigned an unknown liquid to investigate. By measuring the mass and volume of the liquid, they can calculate the density. They will then identify their unknown liquid by comparing their experimental density with a table of values of known densities of different liquids.
