The Evolution of STEM

Journey through scientific milestones with the LEGO Ideas The Evolution of STEM (21355-1), a detailed 879-piece display model for enthusiasts. This set features a meticulously crafted brick-built book base, showcasing significant historical innovations. Builders create mini-models including an early car, a vintage home computer, and the iconic NASA Voyager Probe complete with its Golden Record for potential extraterrestrial discovery. A hidden Technic dial mechanism allows a 3D carbon atom replica to gracefully float upwards while a DNA strand rotates simultaneously. The set includes three pivotal scientist minifigures: Marie Curie, Sir Isaac Newton, and pioneering agricultural scientist George Washington Carver, each bringing a layer of historical authenticity to the model's narrative display.
