Understanding Classification in Mini-Beasts and Invertebrates
Explore the concept of classification through everyday items and living organisms. Learn how items like books can be categorized by size and color, while animals are classified as Vertebrates or Invertebrates within the animal kingdom. Dive into the world of invertebrates, including Arachnids, Annelids, Insects, Myriapods, Gastropods, and Crustaceans, and test your knowledge by classifying different species.

What is classification? Everyday items are classified or organised into groups depending on how similar they are For example, these books could be classified
What is classification? Everyday items are classified or organised into groups depending on how similar they are For example, these books could be classified by size
What is classification? Everyday items are classified or organised into groups depending on how similar they are For example, these books could be classified by colour
What is classification? In the same way, scientists classify or organise living things into different groups depending on how similar they are Within the animal kingdom, animals are classified as either Vertebrates (with a backbone) or (without a backbone) - Invertebrates
Vertebrates vs invertebrates Classify the following animals by clicking on the word vertebrate or invertebrate below them vertebrate vertebrate vertebrate vertebrate invertebrate vertebrate vertebrate invertebrate invertebrate vertebrate vertebrate invertebrate vertebrate invertebrate vertebrate invertebrate Next slide
Classifying invertebrates Invertebrates can be further classified into six main groups Arachnids 8 legs Annelids long, soft body with many segments but NO legs Insects - - - - 6 legs three body segments thorax head abdomen Myriapods Gastropods (= stomach foot) - one slimy foot - sometimes have a shell Crustaceans hard, crust-like exoskeleton 7 pairs of legs (= many feet) - long, segmented bodies with many legs - -
Can you classify these invertebrates? (Click on each picture to see if you were right) Arachnids 8 legs Annelids long, soft body with many segments but NO legs Insects - - - - 6 legs three body segments Myriapods Gastropods (= stomach foot) - one slimy foot - sometimes have a shell Crustaceans hard, crust-like exoskeleton 7 pairs of legs (= many feet) - long, segmented bodies with many legs - -
Now head outside and see if you can find real invertebrates to classify
