Outside the Classroom - Science and English all in one!

In my school, there is a small project which consists on mixing English with Science. About 2 weeks ago we had a meeting with the teacher of this crèdit variable. He explained us that he wants the students to talk in English, to communicate. He is not an English teacher himself so he does not correct students all the time. He uses crosswords, readings, or material he finds in the internet. Since it is an English - Science crèdit variable there is no book assigned to this subject. So, the problem the teacher had was to find all the material he uses in the classes. However, I think it is very encouraging for the students to have a subject like this, it is something different.
