We want to know… How animals are classified How animals change over timeSlide 4: HOW DO WE CLASSIFY ANIMALS?Slide 5: Animals are classified into two main groups: Vertebrates and invertebratesSlide 6: An animal that does not have a backbone InvertebratesSlide 7: An animal that has a backbone InvertebratesSlide 9: Types of Vertebrates Fish Amphibians Mammals Reptiles BirdsSlide 10: Types of Vertebrates Mammals live on land and in water They have hair or fur Mothers nurse young with milk Almost all give birth to live young; a few lay eggs MAMMALSSlide 11: MammalsSlide 12: Types of Vertebrates Reptiles live on land and in water Have scales Breathe air with lungs Lay eggs with leathery shells or give birth to live youngSlide 13: Types of Vertebrates Live on land; some spend time in water Have feathers Breathe with lungs Lay eggs with large shells Most can fly birdsSlide 14: Types of Vertebrates Young live in water, adults live on land Have smooth, moist skin Young breath with gills in water; adults breathe with lungs and through skin as adults Lay jelly-like eggs with no shells AmphibiansSlide 15: Types of Vertebrates Live in water Most have scales Breathe oxygen in water with gills Lay eggs without shells or give birth to live young FishSlide 16: Most vertebrates have special organs in their body them help them to live.Slide 17: ORGANS OF THE BODY Like plants, animals and humans have various body parts and organs (such as the heart, lungs and kidneys) that help them function in life.Slide 18: The Heart The heart is an organ that helps to pump blood around the bodySlide 19: The Lungs The lungs are organs that help to take in oxygen from the air when we breathe and also help release waste gases into the airSlide 20: THE BRAIN The brain controls all of the body’s activitiesSlide 21: The Kidneys The kidneys help to get rid of waste materials from the bodySlide 22: Animals can sometimes be classified by their cyclical characteristics. Animals can be: Nocturnal Diurnal Hibernation Cyclical characteristicsSlide 23: Cyclical characteristics Nocturnal animals are animals that are active at night NocturnalSlide 24: Cyclical characteristics Nocturnal Opossum Koala Wombat Opossum SpiderSlide 25: Cyclical characteristics Diurnal animals are animals that are active during the day and inactive at night DiurnalSlide 26: Cyclical characteristics Diurnal Panther Giraffe Lion Buffalo Squirrel TigerSlide 27: Cyclical characteristics Hibernation is a deep sleeplike state when an animal’s body processes slow down to survive during winter HibernationSlide 28: Cyclical characteristics Hibernation Bear Marmot Hedgehog ChipmunkSlide 29: ANIMAL LIFE CYCLESSlide 30: Some animals including humans , spiders and earthworms look like their parents when they are born. They grow larger in size during their lives, but they do not change their form . They go through direct development Direct DevelopmentSlide 31: Direct DevelopmentSlide 32: Other animals such as grasshoppers and beetles , look nothing like their parents when they are born. These animals change their form during their life cycles. The process of changing form is called metamorphosis. MetamorphosisSlide 33: Metamorphosis is a complete change in body structure throughout the growth stage Metamorphosis The way an organism changes as it develops in its lifetime Metamorphosis can be described as: Complete IncompleteVideo: Life Cycles: Video: Life CyclesSlide 35: Incomplete Metamorphosis Incomplete metamorphosis has 3 stages: egg, nymph and adult . The organism never goes into a period of restSlide 36: Incomplete MetamorphosisSlide 37: Incomplete Metamorphosis Egg - A female insect lays eggs. Nymph - The eggs hatch into nymphs. Nymphs looks like small adults, but usually don't have wings. Insect nymphs eat the same food that the adult insect eats. Adult - The insects stop molting when they reach their adult size. By this time, they have also grown wings.Slide 38: Incomplete Metamorphosis GrasshopperSlide 39: Grasshopper Incomplete Metamorphosis COCKROACHSlide 40: DRAGONFLY Incomplete MetamorphosisSlide 41: CHICKEN Incomplete Metamorphosis chick eggVideo: incomplete metamorphosis: Video: incomplete metamorphosisSlide 43: Complete Metamorphosis An animal undergoes complete metamorphosis if it changes through four distinct stages : Egg, larva, pupa and adult.Slide 44: Complete Metamorphosis Egg - A female insect lays eggs on plant leaves or stems. Larva –The egg hatches into a larva, which looks like a worm. A butterfly lava is known as a caterpillar Pupa -The larva feeds and then makes a hard case around itself and becomes a pupa Adult - The case breaks open after a few days and the adult emerges from the pupaSlide 45: Complete Metamorphosis ButterflyMetamorphosis of a Butterfly: Metamorphosis of a Butterfly Learning the life cycle of a butterflyStage One: Egg: The female lays eggs on a leaf. Each egg grows until it is ready to hatch. Stage One: EggStage Two: Larva: After about one week, a caterpillar hatches from its egg. The caterpillar eats, grows, and molts during this period. The caterpillar stores food energy for the next stage in its life cycle. Stage Two: LarvaStage Three: Pupa/Chrysalis: The caterpillar stops eating. It forms a hard case around itself called a pupa . Inside, the caterpillar goes through many changes. Stage Three: Pupa/ChrysalisSlide 50: PupaStage Four: Adult: After about a week, the adult butterfly comes out. Its body is now completely different. A female butterfly will lay eggs to start a new life cycle. . Stage Four: AdultSlide 52: Complete Metamorphosis BeetleSlide 53: Complete Metamorphosis BeetleSlide 54: Complete Metamorphosis FlySlide 55: Complete Metamorphosis MosquitoSlide 56: Complete Metamorphosis FrogVideo: Complete metamorphosis: Video: Complete metamorphosisComplete vs. Incomplete Metamorphosis: Complete vs. Incomplete Metamorphosis Complete Body structure of the insect or animal changes during the growth stage. There are four stages in this life cycle. Egg → Larva → Pupa → Adult Incomplete Body structure of the insect or animal does not change. The second stage of its life cycle looks like the adult . Thus, the nymph looks like a small adult. In addition, there are three stages in this life cycle. Egg → Nymph → AdultThe pictures show the stages in the life cycle of a beetle.
