In room 6 we have been learning to classify animals scientists classify animals and plants into groups to easily identify ,sort and name them.

Classify = SORT. There are may different ways to group living organism. You can classify animals into two main groups. Vertebrate or Invertebrate. All vertebrates have covering of skin that protects them , A skeleton inside there body , Muscles that help them move, Blood moves through tubes, Lungs or gills for breathing                                                       




                                                                           

90% of all animals are invertebrates

Many live in the ocean because the water helps support their weight.

Some have a hard covering or shell on the outside of their bodies for protection - Insects, spiders, crabs, snails and clams.
