SCIENCE: UNIT 3: HUMAN REPRODUCTION

Activity for Sergio and his friends at 4th Grade Primary.

• The male reproductive system produces spermatozoa. It is formed by the testes, which are inside the scrotum, and the penis, a long organ over the scrotum.
• The female reproductive system produces ova and protects the baby while it develops. It is formed by the ovaries (produce ova), the uterus (where the baby lives), the Fallopian tubes (connect the ovaries with the uterus), the vagina and the vulva formed by the labia.
• Fertilsation is when a spermatozoon and an ovum join together to create a zygote.
• Pregnancy is when the embryo develops inside its mother's uterus. It lasts nine months and ends when the baby is born. The embryo becomes a foetus. The foetus receives food and oxygen from its mother through the placenta. This is connected to the foetus' tummy through the umbilical cord.
• Birth is the process when the foetus comes out of the mother's body. After the birth the doctor cuts the umbilical cord. This is why we have a tummy button.
