Biodiversity: CLASSIFICATION Success Criteria: 1. I can state what is meant by the term classification. 2. I can describe the difference between invertebrates and vertebrates and their subdivisions using examples. 3. I can describe the differences between plants that are flowering or non-flowering. Classification What does classification mean? Why is it important? Individual, pair and share First, answer this question on your own and then discuss it with your partner, and then with your class! 3 mins The Classification System All living things are classified into five main groups called kingdoms. living things plants animals fungi Bacteria (prokaryotes) Protoctists Most living things belong to the animal kingdom or the plant kingdom. Animal Kingdom Vertebrates Mammals Fish Reptiles Amphibians Birds Invertebrates Spiders Insects Crustaceans Molluscs SPIDERS: Characteristics: • No backbone •8 legs •2 body parts •a web used to catch food such as insects •Cold-blooded Examples: •Tarantulas •Daddy Long Legs •Black widow spider INSECTS Characteristics: • No backbone •3 body segments •Most insects have wings •Have antennae •Have a heart but they don’t have blood Examples: •Ant •Dragon fly •Praying mantis MOLLUSCS Characteristics: • No backbone •Their bodies are un-segmented •Many have shells •Some live in water •They are soft bodied •They have two pairs of gills •Molluscs have a muscular foot or tentacles •Most feed on plants Examples: •Snail •Clam •squid CRUSTACEANS Characteristics: • No backbone •Live in water •Have exoskeleton or hard outer shell which protects their body •Have antennae •6-8 jointed legs •Segmented body Examples: •Crab •Lobster •Shrimp •crayfish BIRDS Characteristics: • Have a backbone •Breathe through lungs •Warm-blooded •Have beak or a bill •Have various types of feathers •Birds lay hard shell eggs •2 wings Examples: •Blue Jay •Great Blue Heron •Great Horned Owl AMPHIBIANS Characteristics: • Have a backbone •Most lay eggs •Their eggs have no shells •They use gills, lungs and skin to breathe •They have a three chamber heart •They are cold blooded •They have four legs •They use webbed feet Examples: •Frog •Toad •Salamander •newt REPTILES Characteristics: • Have a backbone •Cold blooded •Four legs •Dry skin •Scales protect body Examples: •Turtles •Crocodiles •snakes MAMMALS Characteristics: • Have a backbone •Warm blooded •Breathe through lungs •Born by a live birth •Adults have teeth Examples: •Humans •Guinea pigs •Whales •monkeys FISH Characteristics: • Have a backbone •They breathe through gills •They have fins to help them swim •Fish are cold blooded animals •They lay eggs to reproduce •They have an endoskeleton or internal framework of the body Examples: •Rainbow trout •Musky •Salmon 7D Classification - Vertebrates Classifying Vertebrates 5 mins Vertebrates are classified into 5 groups. Complete the table of features for each type of vertebrate. mammals birds reptiles body covering hairy or furry skin feathers tough skin with scales how it breathes lungs lungs lungs lungs where it lives mostly on land on land mostly on land on land and in water how offspring are produced most young born alive lay eggs lay eggs lay eggs (in water) amphibians soft, moist skin (no scales) fish scales gills in water lay eggs Confidence Check Show from 1-5 on how confident you are on each success criteria. 1 is not at all confident, 5 is super confident Success criteria 1. I can state what is meant by the term classification. 2. I can describe the difference between invertebrates and vertebrates and their subdivisions using examples. Which group do I belong to? Boys vs. Girls. One boy and one girl will go head to head in the ‘Which group do I belong?’ to game show! I will read out a number of clues; when you think you know which group the animal (vertebrate) belongs to, you must call out your buzzer noise! Girls – bang! Boys – pop! Then the whole class will be asked a question. Then, we start again with a different boy and girl. Which group do I belong to? 1. I live mainly in water. 2. I feed my young on milk. Duck –Billed Platypus 3. I am covered in brown fur. 4. My body temperature is around 30oC. 5. I have a beak that I Student search for food with on Task!

Plant classification Mosses: They have simple leaves and shallow roots, with no proper vascular systems. The leaves are very small and are not covered with a waterproof, waxy cuticle layer. Mosses, Angiosperm and Lichen are often found in damp areas as they dry out easily. They reproduce using spores. Ferns: They have proper roots and stems, and leaf-like fronds. The leaves are not covered in a waterproof, waxy cuticle layer and so they dry out easily and are generally found in damp places. They do have a vascular system. They reproduce using spores. Conifers: They have vascular tissues. They are large plants with proper roots and stems and needle-shaped leaves with a waxy cuticle. They are good at surviving in dry or cold climates. They reproduce using seeds found in cones. Flowering Plants: They have vascular tissues. They have proper roots and stems and have flowers. Their leaves are large and flat and have a waxy cuticle. They reproduce using seeds found in fruits. 5 mins Coniferous Trees •Leaves like needles e.g. pine and spruce trees •Leaves like scales e.g. Cedar trees Deciduous Trees •These types of trees have broad leaves
