Biological webquest

I've begun a webquest with 3rd Biology. The site is in English, though they can write the documents in Catalan and reference pages are in Spanish or Catalan. Anyway, at least, they have to understand the text.

Here is the address:

Surprisingly, pupils in third course seem to translate more easily than those in fourth!!
