The life cycle of an animal shows how it grows and changes from birth
Making observations over time helps scientists to describe changes in animals during their life cycle
The life cycle of animals can be recorded in different ways

Children may think that all offspring resemble their parents.

Show examples of offspring that resemble their parents and of those who do not.

Animal - An animal is a living thing which moves and eats other animals or plants.
Life cycle - A life cycle shows the way in which a living thing changes as it grows.
Change - If something changes it does not stay the same.
Observe - To observe is to look very closely and use other senses too.
Record - To record information is to keep it so that it can be passed on to others. This can be through notes, photos and drawings.
