You are welcome to modify it by adding your own slides or deleting ones you don’t need. Please do not remove the photo credits from any of the photos you use and we would be very grateful if you could leave YPTE’s logo and web address on the relevant pages. We want to encourage more and more young people to learn more about taking care of our world for the future, and the website is a great starting point for this.

- 4. Biodiversity It is estimatedthat there are 8.7 million species on Earth – 6.5 million on land and 2.2 million in the oceans! Photo: Dan McKay

- 7. Photo: Tambako TheJaguar Did you know that nearly 99% of chimp genes are the same as human genes? They are our closest relative!
- 8. Plant or Animal? Photo:3dpete Photo: ReflectedSerendipity Most animals move from place to place, whereas plants do not. Most plants have green leaves and use them to make their own food. Animals cannot do this, so they have to eat other plants or animals to get energy.
- 9. 1. Vertebrate orinvertebrate? Vertebrates are animals with a backbone. They make up less than 3% of the world’s animals. Photo: Valerie Mammals Photo: Berit Watkin Birds Photo: Tambako The Jaguar Reptiles Photo: Vicki DeLoach Amphibians Fish Photo: SF Brit Each group of vertebrates have important similarities.
- 10. What makes ananimal a mammal? Vertebrate Warm- blooded Give birth to live young Females produce milk to feed young Grow hair or fur Lungs to breathe
- 11. What makes ananimal a bird? Vertebrate Two wings Warm- blooded Lay eggs Feathers Two legs
- 12. What makes ananimal a reptile? Vertebrate Dry skin Scaly skin Cold- blooded Usually lay eggs Breathe air
- 13. What makes ananimal an amphibian? Vertebrate Moist scaleless skin Cold- blooded Breathe oxygen through lungs Lay eggs Live on land and in water
- 14. What makes ananimal a fish? Vertebrate Cold- blooded Covered with scales Fins Breathe underwater through gills Lay eggs Live in water
- 15. Invertebrates There are about30 million species of invertebrates in the world! They can be divided into many groups, each with very different characteristics. Invertebrates Insects Molluscs Crustaceans Arachnids Annelids Myriapods Echinoderms
- 16. Photo: Kathi Insects • Largestgroup of invertebrates • 3 parts to their bodies • 2 eyes • 2 antennae • 6 jointed legs at some point in their lives • Often have wings wasp, bee, butterfly, moth, beetle, ant, fly, dragon fly, praying mantis
- 17. Photo: Martin Cooper Arachnids •2 parts to their body • 8 legs • 2 pincers for biting or piercing prey • No antennae spider, scorpion, tick, mite, daddy-long-legs (harvestman)
- 18. Photo: sankax Crustaceans • Ahard outer shell or case • 10 or more legs • 2 pairs of antennae woodlouse, crab, lobster, barnacle, shrimp
- 19. Annelids • Only onemajor part to their bodies • No limbs • Bodies divided into segments Worm, leech
- 20. Molluscs • One mainpart to their body • Some have a shell • All have one muscly foot or tentacles to help them move around • Most are slimy to help them slide along the ground Photo: bramblejungle snail, slug, octopus, oyster, mussel, clam, squid
- 21. Photo: bramblejungle Myriapods The word“myriapod” literally means “many legs”. Do you know which is the centipede and which is the millipede? Clue: millipedes are cylindrical (like a pencil) and have up to 200 pairs of legs, centipedes are flattened and have between 15 and 177 pairs of legs. Centipede, millipede Photo: Colin Avison
- 22. Photo: Selbe Lynn •Live in the ocean • Most have arms or spines that radiate from the centre of their body • Central body contains organs and mouth for feeding Echinoderms star fish, sea urchin, sea cucumber
- 23. Cnidarians Photo: Wally Gobetz •Water animals that have a simple (usually symmetrical) body with a mouth opening • Stinging cells on tentacles around the mouth catch prey jellyfish, coral, sea anemone
- 24. 2. Warm-blooded orcold-blooded? Photo: David Stanley Warm-blooded animals, like these penguins, can stay active whatever the temperature of their surroundings. As the outside temperature rises, this chameleon will become more active. As the outside temperature drops, the chameleon slows down. Photo: Tambako The Jaguar
- 25. Photo: Michael Pennay Arebats birds or mammals?
- 26. Flowering plants Make upover 80% of all plants on Earth Around 352,000 different species (estimate by scientists from Kew Gardens 2008) Photo: solarisgirl
- 27. Photo: James Petts Coniferse.g. pine trees use cones to house their seeds Some non-flowering plants use seeds to reproduce
- 28. Some non-flowering plantsdo not produce seeds and use spores to reproduce Photo: Kristine Paulus Ferns produce spore casings on the underside of their leaves. When the casings dry out, the spores are released into the air.
- 29. 2. How CanClassification Keys Be Used To Help Group, Identify and Name Living Things? Photo: Alexandra Gomez
- 30. Which character are you? Flowcharts can be used to identify many things, including your personality! Photo: GDS Infographics
- 31. Classification Keys Flow charts/branchingdatabases can be used to identify ”all sorts” of things!! Photo: Danny Nicholson
- 32. Does it have legs? YES Howmany legs? 6 Insect 8 Spider Harvestman 14 Woodlouse More than 14 Centipede Millipede NO Does it have a shell? YES Snail NO Is the body divided into segments? YES Worm Pupae & Larvae NO Slug Minibeasts: What is it?

- 35. Litter Animals eat and chokeon it Can trap animals Can leak dangerous substances into soil Can get caught around animals’ limbs Can cause fires to start Can cause injury to animals e.g. cuts Can cause poisoning or internal injury if eaten Litter can harm living things in many ways
