What an exciting trip we had today! We’ve been reading a story called ‘Rosie Revere Engineer’ about a girl who is really interested in making inventions, and so we visited Tower Bridge to find out how it works.
We went into the engine room and saw the huge furnace that would have turned the water into steam, which makes the wheels and cogs turn, which would then open the bridge. We learnt that today the bridge is controlled using electricity, but it was really interesting to find out how it worked when it was made 124 years ago. We had to learn very technical language like crankshaft and cog. We learnt that it is a ‘bascule’ bridge, which means it opens, and found out why it was so important that it had to open.
Then we bravely went up to the walkway and walked on the glass – we could see the river underneath us and boats going under the bridge!
We had such a fun day learning about a really important landmark in London.
