A Race of Discovery.
A Race of Discovery features comparisons of the time it took to complete eleven significant, historical journeys to the time those same journeys would require today. Some of the journeys that you will find on A Race of Discovery are those of Lewis and Clark, Captain Cook, and Christopher Columbus.
Applications for Education
A Race of Discovery does a nice job of showing visitors the significant stops on historical journeys. Unfortunately, the maps are light on details within those stops. That's why I'd use these maps as a model that students could follow to create their own historical journey comparison maps in Google's My Maps. My Maps lets students create maps with multiple layers. I'd have students use that function to create one layer for the historical journey with detailed placemarks then one layer for the current journey.
