Screenshot of tweets on #potcert. You could make a story of tweets of students and publish it on a blog.
Potcert is in Facebook too:
This links to a photo I made near the village we live. The windmills are here because we are near the North Sea, and wind is almost always blowing. In 1930 this was part of the sea, and now it is a polder. The name of our village is Middenmeer, that is litterally translated “Mid Lake”.
The photo is on Flickr. I use Flickr for uploading photo’s. I do follow @ds106dc on twitter, and do the photography challenge. (http://tdc.ds106.us/). The story challenges are excellent homework for students English?
