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).
