This 18 slide powerpoint is the perfect teaching tool for a European Explorers unit. It focuses on Christopher Columbus and gives details about his three ships, his four voyages to the new world, and his relationship with Queen Isabella and King Ferdinand. Created by Beverly Brown & Glynn Brown, it is full of clever animation and illustrations. It also includes facts about Amerigo Vespucci, Vasco de Balboa, Ferdinand Magellan, the line of demarcation, a list of other European explorers of the era, parts of typical ships of the 1400s, and the Columbian Exchange. It ends with a visual representation of how the European explorers changed the perception of the world from flat to round.
