3 Classification Discovery Card Teacher Information
There are millions of different kinds of plants and animals in the world. Each different kind of plant and animal is called a species. We can group species together according to certain characteristics. The diagram below shows how the invertebrates fit into the overall classification tree. Living Things
KINGDOM
Fungi Plants Monera Animals Protista (like plants in many ways but bacteria and blue green algae: (single (single celled organisms do not contain chlorophyll and celled organisms without a nucleus) containing a nucleus) do not photosynthesis. Fungi feed saprophytically or parasitically) Invertebrates Vertebrates (no backbones – they have (have backbones - they an exoskeleton) have an endoskeleton) PHYLUM
Coelenterata Flatworms Roundworms Arthropods Annelids Molluscs Sea urchins Others (starfish & jellyfish) (segmented worms (e.g. snail e.g. earthworm) slug, octopus)
CLASS
Crustaceans Insects Arachnids Myriapods e.g. woodlouse, crab, lobster e.g. beetle, butterfly, bee, e.g. spider, scorpion, tick centipedes & millipedes earwig, fly
Classification terms Naming a species The largest groups are known as phyla. The organisms Every organism is given a scientific name according to in each phylum have a body structure which is radically an internationally agreed system. The name is always different from organisms in any other phylum. in Latin and is either underlined or written in italics. It Organisms in each phylum can be subdivided into is in two parts. The first name indicates the genus and classes. Organisms in the same class share several starts with a capital letter, the second is the species common features. and starts with a lower case letter. An example of classification is given below. A class can be further subdivided into orders, orders into families, families into genera and finally genera The large white butterfly - into species. scientific name: Pieris brassicae Kingdom: Animal A general rule of thumb is that organisms of the same Phylum: Arthropoda species can interbreed successfully whereas organisms Class: Insecta from the same genus but of different species, like the Order: Lepidoptera Brown Bear and the Polar Bear cannot interbreed. Family: Pieridae Genus: Pieris Species: brassicae 3 Classification Discovery Card (cont) Teacher Information

Discovery (suitable for 5 - 12 year olds) sheet 3c as a basis for their work, each child can colour, cut out and stick the pictures into either the There are six Classification Cards in this pack which can ‘Alive’ or ‘Has never been alive’ boxes on Discovery be used as a source of information and/or as the basis sheet 3a.

Bug Dial can be used as an aid to classification of specific Whichever approach is used, you should ask the invertebrates and to explore the characteristics children to consider the following criteria when making common to each phylum or class. their choices: Both Bug Dials are assembled in the same way. The templates should be photocopied preferably to A3 size Does it move? and given to the children who then cut out the dials Can it be a parent? using the dotted lines as a guide.

These sheets can be used in a ‘alive’ or ‘have never been alive’, during a nature variety of ways: walk or scavenger hunt and use their findings to create a display. More about me, bug dial

What to do Carefully cut around each dotted line. Put circle B on top of circle A. Fix it into place with a paper fastener. To use this bug dial Look at the minibeast you are B studying carefully and write down its main features. For instance: How many legs does it have? wh Does it have a hard or soft body? a Has it got wings?
When you have made a list, turn the t
dial until you find the triangle of
g information which is most like the list
? you have made. Now look at the box r
o p opposite which will tell you which u group your minibeast belongs to.
