Water monitoring process

Water Monitoring Process


First thing in the morning I go to the art area table with my iPad. Then I arrange the equipment, and the  beakers full of water. Now we are ready.


                                       pH (1-11) testing


pH testing is simple. First I went to the jelly bean table and got the indicator paper and dipped it in the water. After about two seconds the indicator paper will have started to change colour. Then I took the indicator paper out of the water. Finally I laid the indicator paper on the Universal indicator paper with all the pH colours and markings and wrote the data on the google sheets.

                            

                          Total  solids


Testing number of suspended solids is easy. First I got  the beakers full of water then I observed the water and see if there were suspended solids (not bubbles because it's air). Finally, I wrote the number of solids in the google sheets.


                               TDS


TDS testing is partly complicated because I had use electrical devices. TDS stands for total dissolved solids. First I got the same beaker full of water and the TDS tester. Next I took the cap off the tester and put it in the water. Then I gave the it a swirl in the water for about 10 seconds.

After that I looked at the screen with the results of the water. Finally we recorded the results on the google sheets.


                         Turbidity


Testing the turbidity is simple. First I took the Connections Journal with the different sized letters. The smallest size is 9pt, next is 12pt, then is 24pt and the biggest is 48pt. Next I opened the book and held up the water beaker to the book and looked through the water to the book. Then I saw what PT and it's usually around 24pt or 12pt. Finally I recorded the results on the google sheets.


              Temperature


Testing the Temperature is easy to do. First I got the thermometer and the water. Next I put the thermometer in the water for about one minute. Then I took the thermometer out of the water and looked at the celsius side of the thermometer. The temperature is roughly about 16 to 18. Finally I recorded the temperature in the google sheets.


                Conclusion


In conclusion I learnt how to test pH, number of suspended solids,TDS, turbidity and temperature.

I also learnt that everyone needs to be more careful with our environment and waterways.
