Not long ago, in Welsh schools, the pupils weren’t allowed to speak their native language, Welsh! There was no choice but to learn English. In the Victorian classroom, learning is dull and repetitive, but today’s lesson is not going exactly as the teacher has planned.

The East Coast of the United States of America stretches from the tropical blue seas and white sand of Florida’s Sunshine State to the Canadian border in the North. We begin our journey in the warm and relaxed islands of the Florida Keys, where modern-day treasure hunters are still at work, hunting for sunken Spanish gold.

When the Fisher family of treasure seekers finally struck it rich, the local authorities tried to claim the bounty for themselves, and the case went to the Supreme Court. We learn how the “Florida Keys” got their name, and how these small outlying islands are linked to the mainland.

The town of Marathon in the Florida Keys is home to a unique hospital dedicated solely to caring for sea turtles.
