Kids journeyed through the evolution of cities, from the groundbreaking innovations of the past to the cutting-edge possibilities of the future. They explored architectural marvels like the Library of Alexandria and Roman aqueducts, analyzed modern engineering feats like the Burj Khalifa, and tackled futuristic challenges such as building cities above the clouds. Then they designed their own Cloud Cities, imagining new ways to incorporate nature, transportation, and innovative structures into urban planning for a fun, sustainable future.
