Timelines of Exploration

This year National Geographic is celebrating 125 years of publishing pictures and stories from explorations all over the world. One of the ways that National Geographic is publishing items from their archives is as parts of exploration timelines. There are four timelines of exploration hosted online right now. Those timelines are Underwater Exploration, Women Explorers, Space Exploration, and National Geographic History. The images in the timelines highlight notable achievements in each area. Each of the captioned images can be enlarged.

Applications for Education
These timelines of exploration aren't terribly detailed but they could be good resources to use as introductions to their respective topics. Use these timelines as starters and ask your students to improve upon them with their own research.
