Birds are animals, they are living things that grow and reproduce
The life cycles of different birds can be observed over time and/or researched
Birds are hatched from eggs
When a fledgling or juvenile bird has grown, it becomes a mature or adult bird
Scientists communicate information about life cycles in interesting ways, including life cycle diagrams

Pupils may think the bird inside the egg is not living or that it is a small but fully formed bird.

Explain, using the slides, that the living bird inside the egg grows and forms until it is ready to hatch.

Bird - A bird is a warm-blooded animal that lays eggs and has feathers, wings and a beak.
Egg - An egg is a roundish object with a developing animal inside.
Hatchling - A hatchling is a very young animal that has just hatched from an egg.
Fledgling - A fledgling is a young bird that is developing feathers for flight and is getting ready to leave the nest.
Reproduce - When living things reproduce they create their offspring.
