Joseph tests the water


James showed Joseph how to test the water.  We had a malfunction with the pump yesterday which explains why the ammonia level had gone up again. Joseph and James changed half the water.

James: Salmon Inspector

James was the first student in Room 6 to test the water in the tank.

First he washed his hands with tap water only and measured exactly 5ml of tank water. 


Next he carefully added 7 drops of each reagent, put the lid on the tube and mixed it. After 5 minutes James read the test and the amount of ammonia was too high. 



So we changed half of the water.
