Sorting Living Things Science Grade 3 Ms. Stefanie Mind Map 1 Classifying means putting things into groups based on whether they are alike or different. — The Meaning of Classifying — ANIMALS GROUP M y Bi g F amily I s Re ally Am azing Mammals Characteristics: ● Have hair or fur. ● Produce milk for their young. ● Give birth to their young alive. Egg-laying mammals: Platypus and echidnas. Characteristics: ● Have beaks. ● Have feathers. ● Have a pair of wings. ● Lay eggs with shells. Examples: Sparrow, owl, ostrich and penguin. Birds Fish Characteristics: ● ● ● ● Examples: Guppy, mollies and shark. Have fins (help the fish to swim) Have gills (help the fish to breathe in water) Have scales that protect their bodies. Most lay eggs. Seawater fish Freshwater fish Clownfish Swordtails Seahorses Goldfishes Characteristics: ● ● ● ● ● ● Have three main body parts: head, thorax, and abdomen. Have feelers. Have six legs. Some have wings. Have a hard covering. Lay eggs. Examples: Bee, mosquito and cockroach. Insects Reptiles Characteristics: ● ● ● Have scales. Lay eggs with leathery shells. Are cold-blooded (their body temperature depends on their surroundings) Examples: Tortoise, lizard and snake. Characteristics: ● ● ● ● ● Can live on land and in water. Have moist skin (if their skins dry out, they will die) Their skins can absorb water and oxygen. Are cold-blooded. Lay eggs surrounded by jelly-like substance. Examples: Frog, newt and salamander. Amphibians Other group of animals are vertebrates and invertebrates. Group of Animals Characteristics • Vertebrates • Invertebrates • Examples Have internal bony skeletons (inside their body) Mammals, birds, fish, reptiles and amphibians. Do not have internal bony skeletons. Instead, they have a hard body covering or external skeleton. Insects, spiders and snails. PLANTS GROUP Flo-noflo Flowering Plants • Produce flowers and reproduce by using seeds. • Their seeds are found in the fruits they produce. • The seeds can be moved by wind, water and animals. Examples: Lilac bush, plum tree and tulip. Non-flowering Plants • Do not produce flowers and reproduce by using spores. Examples: Fern, moss and pine tree. We can also classify plants as those that grow on land and those that grow in water. Group of Plants Grow on land Grow in water Examples Azalea, maple tree and cactus Duckweed, hydrilla, and water lily FUNGI • Not a plant or an animal • Come in many colours and shapes • Feed on animals and plants, dead or alive (decay or decompose) • Do not have chlorophyll to make their own food • Sometimes edible, other times poisonous All fungi reproduce from spores. Other examples of fungi are bracket fungus, yeast and mould. BACTERIA Bacteria can multiply very quickly because they reproduce by dividing themselves. We can only see them through a microscope. Like fungi, useful bacteria can help in the production of food and medicine. Mind Map 2 Thank you ☺
