On Friday 15th January the intrepid N5 geography class braved  the sub-zero temperature to complete their river fieldwork. The group spent the morning working with the Water of Leith Conservation Trust to collect key river data for their assignments. The group worked as a team to measure the river’s speed, depth, bedload and to investigate the invertebrates living in the river. Despite the very cold temperatures and the river being faster and deeper than normal, the group worked extremely hard and were a credit to the school and themselves. Well done geographers!!
