    Study Notes

    Animals and Their Adaptations

    • Animals have various adaptations to survive in different environments
    • Some animals run fast (e.g., deer, gazelle) for escaping predators
    • Some animals use camouflage (e.g., chameleon, zebra, arctic fox, polar bear, frog) to hide from predators
    • Camouflage involves blending with the surroundings

    Animals in Danger

    • Many animals are endangered due to human activities
    • Deforestation destroys habitats and food sources for animals
    • Some animals, like the Dodo and passenger pigeon, are extinct (no longer exist)
    • Animals like the Giant Panda and tiger are endangered (at risk of extinction)
    • Endangered animals need protection to prevent extinction

    Types of Animals

    • Terrestrial animals: Animals that live on land
    • Aerial animals: Animals that spend a lot of time in the air (e.g., birds, bats)
    • Herbivores: Animals that eat plants
    • Carnivores: Animals that eat meat
    • Omnivores: Animals that eat both plants and meat
    • Scavengers: Animals that feed on dead animals
    • Parasites: Animals that live on or in a host and feed on it

    Animals' Habitats and Protection

    • Animals adapt to different environments (e.g., thick skin in hot climates)
    • Some animals hibernate or aestivate to survive harsh conditions
    • Animals like seals, penguins, and walruses have blubber for warmth
    • Animals in deserts, like camels, can survive without water for long periods

    Animals and Their Young Ones

    • Mammals feed their young with milk
    • Many mammals give birth to live young
    • Some animals lay eggs (e.g., birds, reptiles, fish)
    • The life cycle of an animal is the process of an animal growing from an embryo to an adult

    The Excretory System

    • The excretory system removes waste from the body
    • The excretory system includes the kidneys, ureters, bladder, and urethra
    • Kidneys make urine, which contains waste products

    States of Matter

    • Matter exists in three states: solid, liquid, and gas
    • Solids have a fixed shape and volume
    • Liquids have a fixed volume but take the shape of the container
    • Gases have no fixed volume or shape

    Separation of Substances

    • Sedimentation: Insoluble substances settle at the bottom of a liquid
    • Decantation: Separating the liquid from the settled substance
    • Filtration: Separating a solid from a liquid using a filter
