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

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

Pupils investigate the density of liquids. In this geometry lesson plan, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.
