History of the World: 3200 BC to 2016 AD

The entire history of the World from the rise of civilization to the present day.

There are a number of takeaways from this compelling video...

. While humans had migrated to most regions of the earth, including the Americas, well before 3200 BCE, large scale "organized humanity" covered only a small portion of the planet until relatively recently.

. Many of the major civilizations over the centuries are never mentioned in K-12 history classes.

. Things change. Sometimes very quickly.

What insights can your class glean from this video?

Confluence

The goal of Confluence is to visit each of the latitude and longitude integer degree intersections in the world, and to take pictures at each location. The pictures, and stories about the visits, have been posted on this site. You can drill in by country, state and confluence point to view the pictures and some remarkable "getting there" stories. There may be one earth, but this drives home its wide diversity.

Everyone is invited to help by photographing any one of these places. There is a confluence within 49 miles (79 km) of your location. Field trip?

Geographic Information System

Geographic Information System covers all the classical dimensions of geography, including weather, fluvialization, etc.

In most countries outside the United States geography is treated as a separate school subject--distinct from general social studies or history. The controversial issue of learning concepts and facts in geography does not emerge in many other countries--it is an educational "given".
