Wikipedia is available in Odia.
It's much smaller than the one in English, but it's there. The best part: you and your friends can improve it. It's a wiki, which means that you can improve it yourself - add as many articles as you want, as long as they are relevant to the encyclopedia, and edit the existing articles. You can even teach the children themselves to edit, thus making sure that they know that it's possible to type in Odia on computers.
I'm super-passionate about making the editions of Wikipedia in various languages better, so please contact me if you have more questions.
