Vertebrates and Invertebrates- Biology- Key Stage 3 & 4

  1. 1. Done by: Mahima De Alwis Vertebrates and Invertebrates Exploring Science 7 Textbook 7D- Classified
  2. 2. Lesson Objectives: L. Obj: To know what are vertebrates and invertebrates. L.Out: Able to identify vertebrates and invertebrates, and differentiate them. W.A.L.T: Types of Vertebrates & Invertebrates.
  3. 3. Starter Activity 1 Looking at these 8 living things, find the variation (differences) and similarities. Write them all in your notebook (Individual work)
  4. 4. Starter Activity 2 /watch?v=8wT5dihdt4E
  5. 5. Starter Activity 2 What did you learn from this video?
  6. 6. Definition: Vertebrate- A vertebrate is an animal which has a spine/backbone. Invertebrate- An Invertebrate is an animal without a spine/backbone.
  7. 7. Types of Vertebrates: 1) Mammals 2) Birds 3) Reptiles 4) Amphibians 5) Fish
  8. 8. What are mammals? Mammals are a group of vertebrates. They have hair or fur. They give birth to live young. They produce milk (only the females) Dolphins, Whales, Lions, Zebras, Human, Rats, Deer, Moose etc. are all mammals.
  9. 9. Challenge: Why is Dolphin not a fish, but a mammal.
  10. 10. What are birds? Birds are vertebrates. They are the only animals which have feathers, They lay eggs in nest. NOT ALL BIRDS CAN FLY! D.Y.K: Penguins are birds! Ostrich, Hawk, Parrot, Eagle, Falcon, Canary, Dove etc. are all birds!
  11. 11. Challenge: What makes bat a mammal, but not a bird? It has feathers alright!
  12. 12. What are amphibians? Amphibians are adapted to live in land, and in water. For more information: Click this link brwww
  13. 13. What are amphibians? Frogs, Tadpoles, Alligators, Salamanders, Urodeles etc. are all amphibians.
  14. 14. What are reptiles? Reptiles are cold-blooded vertebrates Reptiles have dry scales Have lungs for breathing Alligator, Crocodiles, Turtles, Snakes, Black Mamba etc. are all reptiles!
  15. 15. Challenge Why is lizard not a amphibian, but a reptile?
  16. 16. What are Fish? Fish are cold-blooded They lay eggs Fish are entirely made of cartilage Angelfish, Goldfish, Swordfish, Swim Bladder, Hagfish are all fishes!
  17. 17. Discussion Discuss in groups: Which group has the most vertebrates?
  18. 18. MAIN Types of Invertebrates Molluscs Arthropods Echinoderms
  19. 19. What are molluscs? Molluscs have: •Have soft body with bilateral symetry •Many are covered with one or two shell. •More are aquatic, and a few live on land Examples of Molluscs: Slug, Snail etc.
  20. 20. What are Arthropods? Arthropods have: • Have bilateral symetry. • Their bodies are totally covered by an articulate exoeskeleton like armour. • The exoeskeleton moults in a process called moulting. • They have antenna and eyes, simples o compounds( thousands of smaller simpler eyes. • Some are acuatic others are terrestial.
  21. 21. What are echinoderms? Echinoderms have: •Have five-way symetry. Have a skeleton made of hard plates often with spines. •They are covered by a thin skin. •All are marine animals. Echinoderms Examples: Sea Urchin, Star Fish, Brittle Star etc.
  22. 22. In the previous slide, explaining about arthropods, The examples of arthropods are not given. Your task is to name some arthropods. 
  23. 23. Let’s Check: Examples of Arthropods: Spider Tarantula Snake Scorpion (obviously, because you must have seen the picture)
  24. 24. Discuss: Are there more invertebrates than vertebrates? Are there more vertebrates than invertebrates? What group has the most vertebrates? What group has the least vertebrates? What group has the most invertebrates? What group has the least invertebrates?
  25. 25. Plenary (Last Activity) What did you learn in this lesson • Write three more things, you will like to know more about INVERTEBRATES and VERTEBRATES
