Life, the magazine that has built a reputation on amazing photography, has their 2011 Pictures of the Year posted.
There are 107 pictures with topics ranging from the Tsunami, to Hurricane Irene to Iraq to the Royal Wedding and many other topics. In typical Life fashion, the photos are incredible and stimulate the senses and your brain.
This is a great resource to use with classes to discuss some of the biggest stories of 2011 with your classes. The topics can be used in different subjects and photography classes could definitely use these as examples.
