"Information is powerful, but it is how we use it that will define us."
-Zack Matere, Kenyan Farmer.
There is no denying the need to teach kids how to search for information on the internet in efficient, safe manners. There are few sites that teach this skill better than A Google A Day.
A Google A Day is a web search engine by google that helps sharpen search skills by those who participate.
The game is quite simple in design: you're given a question and need to find the answer.
Your efforts are timed, and usually take several layers of searching to arrive at the desired outcome, however, there is of course more than one way to discover the answers. Hints can be given along the way if you get really stuck.
Users can go back in time to complete questions on days they missed, and of course, you could repeat the search of any question as many times as you'd like, trying different query approaches.
Along with the game, is the resource, "Tips and Tricks" which includes the link to "Google Inside Search," where users can learn even more about successful searching techniques in the "Features" and "More Help" sections. (There's plenty more to do at the "Google Inside Search" page, such as enjoy and learn the meanings of all the Google Logos that have graced the past Google pages).
"A Google A Day" is an excellent resource for teachers to use with students together or pass on to students for their own independent study. It can be used as bell work at the beginning of class. I can imagine classes breaking up into teams to compete against each other, or graphing their best times each day. Each daily answer could also lead to even more research for students.
The site is open at the middle school, not sure about the elementary.
