Testing writing

In the morning we have to test water.

Firstly we tested the pH. We dipped in the pH piece of paper. When we took out the ph it showed a colour. Blue is associated with alkaline and red is a Strong acid. We usually get green.

Then we counted how many solids there were in the water because it might have life in it and that means it's healthy.

We got the book ‘Testing the North River’ and we test the turbidity. We grabbed the book. We put the book behind the water and see what number it is out of 9 14 24 40.

To take the temperature we use a thermometer to see what the temperature is. The temperature is usually get 9 our 14 degrees.

Overall, we learnt a lot about water testing like the ph and the temperature and so on.
