“Before meeting Mark our year 3 pupils were unaware of the importance of the brook so close to their homes and lacked knowledge about ecosystems. Mark kindly arranged a talk for each class that was very well organised and had pictures children could relate to. We then organised a stream dipping trip and Mark came for a final visit to hear from the children all about their learning and to find out how they, as tomorrow’s citizens, will look after the brook. Without Mark we would not have had the expertise or equipment to lead such an engaging activity. Invaluable!”
