Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third instructional activity in a seven-part series challenges scholars to find the mass and volume of two unknown...

Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement instructional activity, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete...

Students investigate the density of liquids. In this geometry instructional activity, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.
