School trip for Lumsden primary school Lumsden Primary School went for an exciting school trip to the Canaird Valley to study the Mataura River. They did activities like testing the velocity and clarity of the water. They also tested the depth and flow. They caught living critters that live in and around the river. William’s favourite part was catching the live critters. Eilish’s favourite part was finding out the clarity and Charlotte’s favourite part was catching the critters as well. To test the velocity they ruled out 5m and timed how long it took for a plastic ball to float the 5m. To test the clarity they put 2 litres of the river into a tube and slid a magnet away from where they looked into the tube until they could not see the magnet any more. To test the depth they had a 2m ruler and put it at the edge and then measure 50cm more in to the middle, then measure another 50cm out and so on. The students thought this was a really interesting trip to go on and they all got to gather lots of information about the river to carry on with their inquiry. By Lucy Goodeve
