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...

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the lesson by practicing...

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.
