CN02 OA01: Observe, describe and classify vertebrate animals into mammals, birds, amphibians, reptiles or fish, according to some of their characteristics, such as body covering, breathing structure, presence or absence of mammal glands, among others. 

CN02 OA02: Observe, describe and classify invertebrate animals into different groups, such as crustaceans, insects and arachnids, and compare them with vertebrate animals.

This is an assessment on which students have to apply what they learnt about vertebrate and invertebrate animals, by searching for examples on magazines, newspapers or internet, and classify them according to whether they have or not a backbone. They also need to classify vertebrates into mammals, birds, amphibians, reptiles and fish, and invertebrates into crustaceans, insects and arachnids, relating each of these groups with to different colours.
