Based off of the hit television show NUMB3RS, this lesson has students determine center of mass for a series of objects (approximate JENGA blocks), and then to push each level so that it "hangs over" the level below it. Following this, the total center of mass for the entire structure is calculated, and observations are explored. This lesson is longer than most NUMB3RS lessons, and is very comprehensive. The harmonic series is seen in the amount of "overhang" each level is allowed without disrupting the whole system.
