Challenging questions (I): Do the Dolphins have ears?

During our lesson has came up this question:

DO THE DOLPHINS HAVE EARS?

It seems to be really interesting to surf the net and search some information about it so we decided to post it into a corner in our class. With it we have opened a new space in our classroom CHALLENGING QUESTIONS CORNER. 

After reading the question every student should look about some information and write down in a paper to post it in the corner and also they should write in the following wall.

Some rules they have to follow:

• You can use information from the net, from a book or from yours family. But please quote them.
• If you are going to use this information please, don't copy it. Just read, understand and then rewrite it with your own words.
