Amphibians are animals, they are living things that grow and reproduce
Amphibians are usually hatched from eggs, then live under water before moving onto land
Most amphibians go through big changes (metamorphosis), but not all amphibians go through the same process
Scientific diagrams are used to show the stages in an amphibian’s life cycle
Scientists use simple language and images to help different audiences understand their results

Pupils may think that only birds lay eggs.

Use the lesson resources to make it clear that other animals, including amphibians, lay eggs and these can look different to bird eggs.

Amphibian - An amphibian is a cold-blooded animal that has moist skin, lays eggs and can live on land and in water.
Life cycle - A life cycle is the way in which a living thing changes as it ages.
Larva - A larva is a life cycle stage that some animals go through before metamorphosis into their next form.
Reproduce - When living things reproduce they create their offspring.
Metamorphosis - Metamorphosis is a major change from one form to another.
