6th graders have worked on the digestive tracts of mammals, birds and reptiles seeing the differences that exist.

They have also manipulated the different teeth and what their use is and have checked that the different shapes of beaks are tools and that depending on their shape they can feed on fruit, meat, seeds ... Always with the help of the educator of the Zoo that has solved all doubts!

And finally they have worked on reproduction with a few examples of different groups of vertebrates and with biological material.

It has been a discovery!
