All human beings have a life cycle. This means that they go through a series of changes from the moment they start life to the moment they die.
The process of change is natural and all living things undergo it. The body changes a lot in a short time during puberty which normally happens between the ages of 10-18 years old.
There are different changes for boys and girls:
|Start to grow hair on their faces||Breasts develop and get larger|
|Start to grow hair on their bodies e.g. chest, armpits, groin||Start to grow hair on their bodies e.g. armpits, groin|
|Start to produce sperm in the testicles||Start to release eggs from the ovaries once per month. This causes monthly ‘periods’|
|Voice ‘breaks’ and becomes lower pitched||Hips widen to prepare for childbirth|
The gestation period of a human is 9 months (time taken between fertilisation and birth). What is the equivalent time for an elephant?
