Classes 3 and 4 visited the River Aire at East Riddlesden today.  The trip was organised in partnership with the Aire River Trust.  It was the last of three sessions that have aimed to teach the children about the way we use the river and how we can better look after it.  The children walked down to the river to observe the effects of the recent flooding. They conducted a litter survey and thought about the effect it has on the environment.  Classes 3 and 4 were able to see erosion and deposition in action.  Finally, the pupils were able to identify river invertebrates using a classification key and were told that this is an indicator of the health of the river.
