Google Earth ‘s Engine and the aforementioned Google Earth engine are great ways to institute and demonstrate the concept of “Spatial Journals “ or that very logical Geographical concept of “What is Where, why there ? and why Care ?” . Why Geography?: by Charles Gritzner. From Journal of Geography, March/April 2003.
Certainly our students can create journals with video, images text and personal reflection both globally and locally . Give it a try.
A number of good and short YouTube video’s on the ever changing earth with short geovisual representations using Landsat imagery with the Google Earth Engine .
1/A Planetary Perspective: With Landsat and Google Earth Engine
Since July 1972, NASA's Landsat satellites have gathered images over the entire land surface of the Earth, creating the most complete record ever assembled. These images, archived at USGS, reveal dynamic changes over time due to human activity (deforestation, urbanization) and natural processes (volcanic eruptions, wildfire). Now, Google Earth Engine allows scientists, researchers and the public to easily view and analyze this treasure trove of planetary data. http://earthengine.google.org.
Specific Ones:
2/Amazon Deforestation: Timelapse
Explore a global timelapse of our planet, constructed from Landsat satellite imagery. The Amazon rainforest is shrinking at a rapid rate to provide land for farming and raising cattle. Each frame of the timelapse map is constructed from a year of Landsat satellite data, constituting an annual 1.7-terapixel snapshot of the Earth at 30-meter resolution. The Landsat program, managed by the USGS, has been acquiring images of the Earth's surface since 1972. Landsat provides critical scientific information about our changing planet.

3/Drying of the Aral Sea: Timelapse
Explore a global timelapse of our planet, constructed from Landsat satellite imagery. With water diverted to irrigation, the inland Aral Sea has shrunk dramatically. Many areas were completely dry by 2009. Each frame of this timelapse map is constructed from a year of Landsat satellite data, constituting an annual 1.7-terapixel snapshot of the earth at 30-meter resolution. The Landsat program, managed by the USGS, has been acquiring images of the Earth's surface since 1972. Landsat provides critical scientific information about our changing planet.

4/Las Vegas Urban Expansion: Timelapse
Explore a global timelapse of our planet, constructed from Landsat satellite imagery. This timelapse from 1999 to 2011 captures the rapid growth of Las Vegas, Nevada, the fastest growing city in the United States over the past two decades. Each frame of the timelapse map is constructed from a year of Landsat satellite data, constituting annual 1.7-terapixel snapshot of the Earth at 30-meter resolution. The Landsat program, managed by the USGS, has been acquiring images of the Earth's surface since 1972. Landsat provides critical scientific information about our changing planet.

Some other Interesting examples from Google outreach follow:
1/Introduction to Google Earth Outreach
Explore, create and connect with Google Earth Outreach. Explore our gallery of public-benefit maps in the Showcase. Create maps with the help of online tutorials and tools. Connect with others and apply for grants in the Community.
2/Maps for Good, with Google Earth Outreach
Nonprofits are using maps to solve the world's most pressing issues, from environmental and humanitarian issues to disaster relief. They are learning how with the help of Google Earth Outreach, http://earth.google.com/outreach.
Google Earth Outreach in Canada
Celebrate the launch of Google Earth Outreach in Canada, and get inspired by the amazing examples of nonprofit organizations already using mapping tools in their work:
"Caribou Migration," by Golder Associates Ltd & Hugh Stimson
"I Am Fish," by the David Suzuki Foundation
"Canada's Boreal, the World's Largest Intact Forest," by Pew Environment Group
"Voices on the Land," by Okanagan Nation Alliance, Gregory Kehm Associates & Ecotrust Canada
"Oil & Water Map," by the Living Oceans Society
"Natural Capital," by the David Suzuki Foundation
Finally for a Friday afternoon I just wanted to show you all that the black and white photograph is not dead . Some spectacular images from Africa that are always good
Have a great weekend
