  1. Classification Grouping & Identifying Living Things This Powerpoint is hosted on www.worldofteaching.com Please visit for 100’s more free powerpoints

  2. Think of three examples where we group things. • Grocery store • Clothes in our drawers • Cabinets in our kitchen • Why do we group these things? To make life easier.

  3. Why do we classify? The grouping or sorting of things based on something (trait) that they have in common Makes life or the studying of life easier Used by all people, but especially by scientists when they want to learn about a group.

  4. How do scientists classify? Scientists classify to make things easier to study They split all things (matter) into two groups-----living and non-living http://player.discoveryeducation.com/index.cfm?guidAssetId=5F116849-9C10-4B80-9DD2-45A817FAF697&blnFromSearch=1&productcode=US

  5. What do all living things have in common? Grow and change Movement Need for food, water, and air (use energy) Reproduce (make more) Respond to environment Adapt (deal with) to their environment Made up of cells

  6. Classifying Living Things • We put all livings things into two large groups: • Animals • Plants

  7. Animals • Animals are spilt into two major groups: • Vertebrates • Invertebrates http://player.discoveryeducation.com/index.cfm?guidAssetId= 3DD50E70-F970-457B-A39C-203FA8F18A01&blnFromSearch=1&productcode=US

  8. Vertebrateshttp://player.discoveryeducation.com/index.cfm?guidAssetId=2F1739D6-485F-42A0-8A13-54E46C2FBA15&blnFromSearch=1&productcode=USVertebrateshttp://player.discoveryeducation.com/index.cfm?guidAssetId=2F1739D6-485F-42A0-8A13-54E46C2FBA15&blnFromSearch=1&productcode=US • These are animals with a backbone. • There are five groups of vertebrates: • Amphibians • Birds • Fish • Mammals • Reptiles

  9. Warm Vs. Cold All animals are either warm or cold blooded http://player.discoveryeducation.com/index.cfm?guidAssetId=A0B14564-7194-4604-92C9-4DE24FD40D6A&blnFromSearch=1&productcode=US Warm blooded- keeping a constant body temperature and adapting (doing something to deal with) the outside temperature Ex: shed, put on a coat- mammals and birds Cold blooded- move from place to place to change or adjust body temperature- fish, reptiles, amphibians

  10. Birdshttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=USBirdshttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=US • Have feathers, wings and hollow bones • Lay hard shelled eggs • Warm blooded • Breathes with lungs

  11. Mammalshttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=USMammalshttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=US • Have hair and produce milk • Most are born alive and can not take care of themselves • Warm blooded • Breathes with lungs

  12. 3 Kinds of Mammals Monotremes- mammals that lay eggs- Ex: platypus Marsupial- give birth to undeveloped babies that continue to develop in a pouch- Ex: kangaroo Placental- develops inside its mother’s body until its body systems can function on their own- Ex: humans

  13. Reptileshttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=USReptileshttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=US • Have dry scales • Lay leathery shelled eggs • Cold blooded • Breathe with lungs

  14. Fishhttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=USFishhttp://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=US • Have wet scales • Lays eggs in water • Lives in water-breathe air through gills • Cold-blooded

  15. Amphibians (double-life)http://player.discoveryeducation.com/index.cfm?guidAssetId=239BE623-7C44-4FC9-AC0B-87D06A4B88C7&blnFromSearch=1&productcode=US • Have moist skin • Lay jelly coated eggs in water • Lives on land and water • Cold-blooded • Go through a metamorphosis ( a complete change) • Breathe with lungs

  16. Summary of Vertebrates

  17. Invertebrates • These are animals without a backbone or brain.

  18. Arthropodshttp://player.discoveryeducation.com/index.cfm?guidAssetId=739d413d-9ac1-4332-8291-abcaf75c3b4b&blnFromSearch=1&productcode=USArthropodshttp://player.discoveryeducation.com/index.cfm?guidAssetId=739d413d-9ac1-4332-8291-abcaf75c3b4b&blnFromSearch=1&productcode=US • Have lots of jointed legs (appendages) • Segmented (or sectioned) bodies • Have an exoskeleton that must be shed (molt) because it doesn’t grow with the animal • They have top/bottom symmetry • There are four groups of arthropods: • Arachnids • Centipedes & Millipedes • Crustaceans • Insects

  19. Arthropods – Arachnidhttp://www.brainpop.com/science/diversityoflife/arachnids/ • Have four pairs of legs (8 total) • Have bodies divided into two sections- abdomen (body) and the head • Ex: spiders, ticks, scorpions

  22. Arthropods – Insectshttp://www.brainpop.com/science/diversityoflife/insects/ • Have three pairs of legs • Bodies divided into three sections (head, thorax, abdomen) • Often have wings • Go through a metamorphosis (a change) complete/incomplete • Ex:butterflies, grasshoppers

  23. Crawl on a single fleshy pad. Can have a shell Ex: slugs, snails, squid Molluskshttp://player.discoveryeducation.com/index.cfm?guidAssetId=739d413d-9ac1-4332-8291-abcaf75c3b4b&blnFromSearch=1&productcode=US

Spongeshttp://player.discoveryeducation.com/index.cfm?guidAssetId=739d413d-9ac1-4332-8291-abcaf75c3b4b&blnFromSearch=1&productcode=USSpongeshttp://player.discoveryeducation.com/index.cfm?guidAssetId=739d413d-9ac1-4332-8291-abcaf75c3b4b&blnFromSearch=1&productcode=US • Have bodies made of loosely joined cells
