Members of Code Club went on a trip to Tower Bridge. We first went to the Engine Rooms and our guide, Isabel, told us the history of Tower Bridge (we found out it will be 130 years old in June!) and how it works. Then we walked across the high-level glass-bottomed walkways. Some of us didn't like that at all! We even saw a helicopter coming in to land to take part in the Ceremony of the Constable's Dues. 

After lunch in a classroom in one of the 'towers', we put together models of one of the bascules to understand how they work and then we went on Scratch to write the code to raise the bascules. When we left, we were lucky enough to see some of the Royal Marines marching past the Tower of London at the end of the Ceremony. 

It was a very exciting trip!
