I don't know about you, but I find it hard to recall all that has happened in the past month, let alone an entire year. An end of a year is often my favorite time because it offers a time of reflection and remembrance. Thanks to the incredible amount of use that Google search gets, we can actually look back on a year just by looking at the trends and hottest searches done on Google. Through the Zeitgeist 2012 Review from Google users can watch a video of highlights (which I have embedded below), see the trends for searches, the top searches in various categories (which can also be downloaded), break down searches by country by drop down or on a map, and if so inclined discover what you searched for the most (if you enabled web history in your Google profile.
When we all head back to school in 2013, this might be a great video to show at the beginning of class and allow students to reflect on people and events they recognize or that has been discussed in class. As mentioned above, you can download a copy of the list. This could be a helpful classroom resource to use in the classroom through the years showing changes and similarities in Google search trends.
