History of the World: Every Year
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.
. Who knew there were so many Caliphates?
. During the Roman Ages, there were only about 200 million people on earth, about the same population as present day Pakistan or Brazil.
. Humans did not reach the 1 billion mark until 1802. A little over 200 years later we're at 7.6 billion.
. Things change. Sometimes very quickly.

What is Geocaching?
Geocaching is an outdoor recreational activity, in which participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called "geocaches" or "caches", anywhere in the world. This video shows what geocaching is, how it works and how you can become a part of it.

You can do something similar in your own school or neighborhood by creating caches and providing directions. A great way to get your students outdoors.
This site has digitized one of the greatest historical atlases, Charles O. Paullin and John K. Wright's Atlas of the Historical Geography of the United States, first published in 1932. This digital edition reproduces all of the atlas's nearly 700 maps. Many of these maps are enhanced here in ways impossible in print, animated to show change over time or made clickable to view the underlying data.
Google Earth has expanded to run on just about any platform (desktop, browser or mobile device) and now includes the Moon, Mars and the nighttime sky. innovative software application for 3D imaging of the ENTIRE EARTH. You can zoom in on a nearby building or explore galaxies millions of light years from Earth!
Using this technology, you can see mountain passes and other topography and make history and earth sciences classes come alive.
With the advent of the smart phone, just about everyone now has access to a high quality GPS receiver. There are a wide variety of GPS apps available to view and use that information, from Google Maps to specialized apps for hikers and boaters. GPS Test is an example of a simple, free app that can be used to determine your place on the earth – latitude, longitude and altitude – and to show how GPS works. Who knew there were that many GPS satellites overhead.
James Miller has created FlashMapper's Atlas of the United States. It tells the story of the US, past and present, through different sets of maps. Explore state expansion through the Civil War or past elections with now-extinct political parties. Free from the Apple App store.
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 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".
