It was in a beautiful spot on the Williams River at Dungog - and we had perfect weather. Not too hot, not too cold! |
They were then taught how to take the water sample... |
And the kids took it in turns to do their own... |
They then measured air and water temperature, |
measured the pH of the water.. |
a perfect 7 in this case, |
then measured the salinity of the water (measured by electrical conductivity), |
and the turbidity of the water (how clear it is). |
Then after lunch, we went back down to the river and did dipnetting and bug identification. |
