Animal intro Animal intro Presentation Transcript

  • Get your new textbook andput your name in the frontcover.Fill out the textbook form.Work on the textbookpacket.
  • What things do all animalshave in common?What are some examples ofanimals?
  • Multicellular Many EUKARYOTIC cells with no cell walls Form tissuesReproduce sexually Some can reproduce by “budding”
  • Develop from embryos Stages of development
  • Have specialized parts;organsMoveAre heterotrophs/consumers
  • Choose any animal.Use the 6 statements on the prior slidesto EXPLAIN why it is an animal.You MAY NOT use the underlined words.Ex: Monkeys can climb, …
  • Vertebrates – skull & backbone less than 5% of all animals Invertebrates – no backbone •Most of the animal kingdom!
  • Analyzing Data…•Look at the paper Mrs. Lock gave you.•Answer the questions regarding the graph of the distribution of the animal kingdom.
  • 9 Groups… Porifera Cnidaria Platyhelminthes Nematoda Invertebrates Annelida Mollusca Arthropoda Echinodermata Chordata Vertebrates
  • What are the 6characteristics that makesomething an animal?What group of animals is thelargest?
  • What is the partlabeled at A on themicroscope picturedhere?How much does partA magnify your slide?How do you figureout total magnificationof a slide?
  • With your group, putthe slips of microscopedirections in order fromthe first step to the last.
  • What are some ways animals differ?
  • Definition orBehaviors explanation Examples Predator: eat animals Prey: eaten In order to stay alive; Camouflage: blend in with1. Survival Find food, water, avoid background being eaten; use little energy Coloration: bright, etc to warn Doesn’t depend upon2. Innate learning or experience; Communication Influenced by genetics Modified by watching or3. Learned experiencing Language
  • Definition orBehaviors explanation Examples Hibernation: period of inactivity; lower body Things done in response to temperature; winter4. Seasonal the season Estivation: slow period; hottest part of summer; reduced activity Biological clocks: natural cycles; clues from nature; seasonal, hibernation,5. Rhythms Internal clocks or calendars migration, etc. Circadian: around the day; daily cycles; sleep, eat, etc.
  • Definition or Behaviors explanation Examples How animals find their way Landmarks; mental maps;6. Navigation from place to place smells, etc Communication; territory; Interactions with others of pheromones; noise, body 7. Social the same species language, touch; live in groups
  • Asymmetry: no symmetry; irregular Radial: like a wheel; Radiate from center Bilateral: split down the middle; 2 identical sides
  • What characteristics makesomething an animal?What are some animal behaviors?Describe 1 type of symmetry.
  • NATURE VS NURTURE…Innate: controlled by geneticsLearned: innate behavior thatis modified
  • Critical Thinking & Reading• Read “Masters of Navigation” on the activity sheet Mrs. Lock gave you.• Answer the questions regarding innate and learned behavior.
  • Finding Food…To find the most foodusing the least energy
  • Camouflage…Blend inSome change color or appearance
  • Defense…Protection from predators Chemicals Herds
  • Warning Coloration…Avoid animals with colorsand patterns associatedwith pain, illness, etcStay away!!!
  • Migration…Travel from one place toanotherObtain food, water,nesting
  • Hibernation…Period of inactivity Decreased body temp In winter Food is scarce
  • Nonfiction Reading• Read the article on bat hibernation on page 24 of your textbook.• Answer the questions on the activity page Mrs. Lock gave you.
  • Estivation…Period of reducedactivity In summer
  • Biological Clock…Internal control ofnatural cyclesUse clues fromsurroundings to set“clock”When to fly south
  • Internal Clock Activity• Find the Internal Clock activity• Using a stopwatch, have 1 partner estimate the time of 60 seconds. Repeat the trial 2x.• Estimate 60 seconds while taking pulse.• Estimate 60 seconds while breathing.• Switch partners.• Answer the questions.
  • Circadian Rhythms…Daily cyclesWhen to go to bed
  • Yawning Cycles• For 1 day, keep track of the number of times you yawn. Take note of what times and what conditions are present when you yawn.• Graph your data on the activity sheet Mrs. Lock gave you.
  • Navigation…Find way from one place toanother
  • Between animals in the same species
  • Communication…Smell; pheromonesSoundBody languageTouch
  • Living in Groups…Pros Help spotting predators Help finding/killing foodCons Attract predators Compete for food Transmit disease
  • Animal Behavior Assignment• Make a chart – Behavior / Definition/ Example / Innate or Learned• List 5 of the 10 behaviors discussed today.• Write a definition for each behavior.• Then, give an example for each behavior.• Finally, identify whether your example is innate or learned.
  • Behavior Definition Example Innate or Learned?
