Stream Study

     Monday 15 March Room 14 went to camp. During the first day we went to the Wainui stream and did stream study.

      There were many activities like: Mrs Atkinson was doing erosion and stream cover, Kathryn was measuring water temperature, Trudi and Jack were measuring the clarity of the water, Tim and Frank were showing water smell and colour, Ange and Athena were looking at algae and Russell and Jemuel were studying the little critters in the water.

    Each activity was different. The stream cover and erosion result was good because the stream had a few trees and no sign erosion. On Kathryn’s station people measured the temperature in two different areas. In the shallow area the temperature was 21 Celsius the deep bit was 18 Celsius. With Jack and Trudi people looked through a tube at a black piece of plastic through the water as it moved away. The person would say when the black piece got blurry and the amount of CM it had moved was the result.The next station was with Tim and Frank. They put water on a tray and we looked at it and smelt it to find out its colour and smell. The water had a faint smell and was slighty murky.
    Next, there was algae searching with Athena and Ange. We got microscopes and looked at the algae, there was a fair amount but not too much. Last there was critter search with Jemaul and Russell where after watering down sticks the group would search for little creatures like mayflies and stoneflies.
    We all had heaps of fun.
