PERU: The Nazca Lines are a group of ancient geoglyphs in Peru. They are made out of naturally occurring elements, like rocks, stones, or earth. These trenches–running in all different directions in this part of Peru–appear to be roads from ground level. However, from an airplane, you can see that they are actually huge designs depicting anything from hummingbirds and lizards to astronauts and spiral shapes. Drones are helping to uncover even more in recent years. HERE is one activity you can do in class or at home. Because my classroom was carpeted last year, students recreated these designs with masking tape on the floor.
