A Dastardly Density Deed

by: Mike Shaw

This burglary mystery captures students' interest as they analyze how the mass-to-volume ratio of a liquid determines its density. As they observe the mass change while the volume remains constant, they begin to understand why the density increases.

Participating in this hands-on, exploratory investigation allows students to use a trial-and-error approach that stimulates their thinking and leads to long-term retention of learning.
