Why do people wear poppies?

The week before 11 November, you'll see people on the TV and in the streets wearing a poppy. But what are they for?

Poppies are red flowers which are worn to show others that you are remembering those who died for their country.

The reason poppies are used is because they are the flowers which grew on the battlefields after World War I ended.

Poppies are also used to raise money for servicemen and women who are still alive but whose lives have been changed by war.

The charity that runs the Poppy Appeal is called The Royal British Legion.

Each year, volunteers will sell these poppies in the street all over Britain.

You can decide how much money you want to give to the poppy sellers.
