How tall can a tower rise? How far can a bridge span? Can students build a tower three times taller by using three times the amount of materials? Students answer these questions and others as they learn how to apply physics principles to solve real-world problems. Using LEGO building components, students investigate structural designs and employ gears, cams and pendulums to explore kinetic and potential energy. Working individually and in teams, they build towers and Ping-Pong launchers.
