    Study Notes

    Vertebrates

    • Vertebrates are animals with a backbone.
    • Scientists group vertebrates into five groups: mammals, reptiles, amphibians, birds, and fish.

    Mammals

    • Covered in hair or fur.
    • Give birth to live young.
    • Mothers nurse young with milk.
    • Breathe using lungs.
    • Live on land or in the sea.
    • Many land mammals have four legs and protruding ears.
    • Are warm-blooded.

    Reptiles

    • Covered in scales.
    • Dry skin, some with hard shells.
    • Usually lay eggs, some give birth to live young.
    • Breathe using lungs.
    • Can have four legs or no legs.
    • Have ear holes instead of ears.
    • Are cold-blooded.

    Amphibians

    • Moist skin (no hair or fur).
    • Lay many eggs.
    • Breathe using lungs or gills.
    • Live on land and in water.
    • Some have four legs, some have none.
    • Often have webbed feet.
    • Have ear holes instead of ears.
    • Are cold-blooded.

    Birds

    • Covered in feathers.
    • Lay eggs.
    • Breathe using lungs.
    • Most have wings and can fly.
    • Have two legs, feet, claws, and a beak.
    • Have ear holes instead of ears.
    • Are warm-blooded.

    Fish

    • Live in water.
    • Covered in slimy scales.
    • Have fins and a tail for swimming.
    • Lay many eggs.
    • Breathe underwater using gills.
    • Are cold-blooded.

    The Ostrich

    • Flightless bird.
    • No teeth.
    • Swallow stones to grind food.
    • Adults carry about 1000 grams of stones in their stomachs.

    Invertebrates

    • Animals without backbones, divided into four groups:
      • Cnidarians
      • Annelids
      • Arthropods
      • Mollusks

    Separating Mixtures

    • A mixture is a combination of two or more substances that can be separated.
    • Methods for separating mixtures include:
      • Handpicking
      • Sieving
      • Filtration
      • Magnetism

    Sieving

    • Used to separate different-sized particles.
    • Particles that are small pass through the sieve holes. Large particles do not.
    • Example: separating marbles from flour.

    Filtration

    • Separating a solid from a liquid when the solid does not dissolve (insoluble).
    • Uses filter paper in a filter funnel.
    • Liquid passes through, solid remains on filter paper.
    • Example: separating sand from water.

    Magnetism

    • Separating a magnetic material from other substances.
    • Example: separating nails from broken glass.

    Measuring Liquids

    • Volume is the amount of space a liquid occupies.
    • Units are milliliters (mL) and liters (L).
    • Use measuring instruments (like beakers, measuring cylinders).
    • Instruments must be on a flat surface.
    • Read volume at eye level.
    • Liquid level is curved (meniscus).
