Science - Life Cycles in Humans and Animals
All animals, including humans, are born, they get older and bigger and some will go on to have children. In the end, all animals die. We call this a life cycle.
Watch this short clip to learn about life cycles.
Animals are small when they start life. Over time they grow bigger and their bodies change.
When they are grown up, they might reproduce and have young animals of their own. These children will get older and may eventually also have children too, and so the life cycle keeps going!
Have a go at the two re-ordering activities below. Can you put the life cycle of a butterfly and chicken in the right order?
