This document discusses the classification of living and non-living things. It defines living things as those that are born, grow, eat, breathe, reproduce and die, such as people, animals and plants. Non-living things do not eat or grow and include things like the sun, rocks, cars and tables. It then focuses on classifying animals based on their skeleton, means of birth, diet, and movement. Vertebrates are defined as having a skeleton and backbone, while invertebrates do not.

2. Living things
• Living things are born, grow, eat, breathe,
reproduce and die.
• People, animals and plants are living
things.

3. Non-living things
• Non-living things do not eat or grow.
• The Sun and rocks are non-living things.
• Cars, tables, or books are non-living
things.

4. Animals and plants
• Plants cannot move from one place to
another.
• They are fixed to the ground
by the roots.
• Plants make their own
food using water,
minerals and sunlight.

5. Animals
• Animals can move from one place to
another.
• They need to eat plants
and other animals
to live.

6. Classification of animals
We can classify animals using different
criteria:
• The skeleton:
- Vertebrates have
a skeleton
- Invertebrates
do not have a
skeleton

7. Classification of animals
The way animals are born:
• Viviparous animals are
born from their
mother’s womb.
• Oviparous animals
are born from eggs.

8. Classification of animals
• The food they eat:
– Some animals eat other animals. They are
carnivores.
– Some animals eat plants. They are
herbivores.
– Some animals eat plants and other animals.
They are omnivores.

9. Vertebrates
• Vertebrates have a skeleton made up of bones
and a spinal column.
• Vertebrates’ bodies have several parts:
- head
- trunk
- limbs (arms, legs,
wings or fins)
- tail (a extension of
the spinal column)

10. Classification of vertebrates
• Mammals
- They are viviparous. They drink mother’s
milk when they are babies.
- They breath with lungs.
- Most of then can walk,
but others like dolphins
or whales can swim.
- Bats can fly.

11. Classification of vertebrates
• Birds
– They are oviparous.
– They breath with lungs.
– They have two wings. Most of then
can fly.

12. Classification of vertebrates
• Amphibians
– They are oviparous.
– When they are babies
they live in water.
They breath with gills
and they can swim.
– When they are adults they live on land.
They breath with lungs and they can walk.

13. Classification of vertebrates
• Reptiles
- They are oviparous.
- They breath with lungs.
- Snakes have no legs
and they can crawl.

14. Classification of vertebrates
• Fish
– They live in water.
– They are oviparous.
– They breath with gills.
– They have fins and they can swim.
