Last week I went on a trip to Carsington Water, a reservoir in Derbyshire. The sun was out but it was a very cold day and the black clouds were gathering. The purpose of the visit was to see what the visitor centre could offer as an educational resource. It had very good interactive displays and lots of information about where our water comes from and how it is cleaned for household use. I found it informative and fun as an adult but I feel sure it would be equally so for children.
