Chile's 'Penguin Revolution'

In 2006, hundreds of thousands of school children in Chile took over their schools and marched in the streets, in a protest about inequality in education.

It was known as the "Penguin Revolution" because of their black and white school uniforms.

The students were demanding good quality education for all children, regardless of whether they were rich or poor.

Grace Livingstone speaks to Karina Delfino, who was a 16-year-old school girl and one of the leaders of the movement.
