Water monitoring process

 Water  monitoring process
21/5/2015
Every morning I test the Avon river water with the indicator  paper. The indicator paper measures for how much acidity is in the water. If the colour turns red or purple it will burn your insides if you consume it, but if it turns green you can drink it. 

Next I test the tds, the tds checks for how much dissolved solids and and bacteria are in the water. 

Next I check the temperature I do this in the morning because if I checked it in the afternoon the temperature would changed.
   
We are testing water to learn about science to see if the water is healthy.
