As part of their work on the River Severn, Year Six pupils visited Diglis on Wednesday to see the link between the canal and the river.
RGS pupils had the opportunity to see first-hand two different types of lock and learnt about why the canal builders had to build them.
The second type of lock was on the river slightly downstream and this one differs in the fact that the gates are motorised and that it allows boats to avoid a weir.
On Thursday they extended their learning using Lego WeDo to build powered lock gates and then program them using their iPads. All pupils were successful in the task and went on to use a motion sensor to start the program when a boat approached.
