Water monitoring process

                         Water monitoring process

Miss Webster brought some water from the creek by her house for us to test as part of our Waterways inquiry.

Firstly we tested the pH which shows if living things could live in the water and to see if the water is clean and healthy.

After that we tested the temperature with a thermometer. We tested it in the morning so it is closer to the time that we got it so it wouldn't have warmed up.

We're also tested household items for their pH to see if they are neutral like the water, or high. If it's a juice it will be in between 3 and 4 pH because it's acidic and if it is a powder you have to put water in it to dissolve it so we can see. It will probably be in between 1 and 2 pH.

After we did all of that we checked the turbidity with numbers on the side like for example 09.02  and to see if the water was clear with numbers from 9 to 40. If you could see 9 then the water was clean and if you couldn't see 40 then the water wasn't clean. We used the numbers to see if the water's safe to live in. Nine was the smallest and if you can see it then the water is clear and safe to live in. The biggest one is twenty four and if you can't see it then the water is dirty and not safe to live in and the bugs could die because the water would be murky and they wouldn't be able to see anything.  

Next we typed the results on the chart on our iPads. We did this to see if every day the water changes.

Overall, during our water monitoring, I found out what pH means.

  1. Sounds like a very interesting process Sophie. What were the results like? Maybe you could post your chart so we can see what results you got.. I'd love to see it! Sounds like you found out more than just what pH means. I can see a lot of different learning in this process and I think you have found out more than you realise! Well done :)
