Depending on the level of your students, you could maybe include podcasts, online radio stations, online dictionaries or children's website (I think the BBC has one, for example).
Keeping in mind that Wikipedia is not always reliable, it is still useful for a first impression of a topic, and it has some articles in "Simple English", as opposed to "English".Anyway I think that an important part of media literacy is too be aware of the fact that some sources are less reliable than others.
"Privacy" might be another aspect to teach - considering youtube and other platforms llike that.
To prepare classes there is a tool called "Lingofox" which can make gap texts, c-tests, and other forms of exercises out of any text you have once entered. You can even define the level of difficulty by saying how many gaps the text should have or giving (or not giving) the students the words to be put in. The drawback (maybe) is that it is in German, but if you can find someone to translate the buttons, it might still work for you. (Or use dict.leo.org, which is a great online dictionary German-English).
The students could make powerpoint presentations or write texts with words. You could make them swap documents with a partner and correct the text using the comment function. Later they might hand in (or email) you the text.
Epals obviously would be something, too ;)
Oh, and I love Google Earth! See the world from above..... so beautiful! (And interesting, getting an impression of the landscape, population density, infrastructure at least as far as roads are concerned, etc.)
I hope you can use some of these ideas.
All the best,
