Students use PhET Sim to explore density in an inquiry based lab. Check out the Sim here:: http://phet.colorado.edu/sims/html/density/latest/density_en.html?fbclid=IwAR09bUeRxx_DckEweccfg2_1DozdustsrS4RJYOtwDkaHwiyJ6RDzLTofPIThis lab first walks students through finding volume through water displacement. Then students explore densities of different materials with the same mass but different volume, same volume but different mass, and then same density but different masses and volumes. Finally
