Water monitoring process

Water monitoring

This term our topic is science and we're learning about water monitoring.

Every day Ms Webster sets the arts table with all the equipment we need for the water testing then we get started.

Firstly we tested the temperature to see if the water is healthy and cold and under 20 degrees it will be healthy to swim in the water.

Secondly we measured the turbidity to see how clear the water was. We got out a journal which had four sentences. There was small, medium, large and extra LARGE. We saw which one we coud see the clearest.

Thirdly we tested  TDS. This stands for total dissolved solids. It tells you how much dissolved solids is in the water. We have to swirl it around to see what the results are.

Fourthly we tested pH. pH is measured with a little yellow piece of paper that we put in the water to see what colour it matches on a guide sheet because if it is a red or an orange colour it’s not safe to drink.

Fifthly we tested number of suspended solids. This is how many invertebrates and 

other animals are in the water because the invertebrates and the other animals 

keep the water clean.

The second to last thing we do is the smell. But mostly when we do the smell it doesn't smell like anything because water doesn't really smell unless it's salt water or polluted water.

The very last thing we do is record the weather condition so we see if it has been raining at night. So every night when it rains, hails or snows at night we wrote it down in the sheets app that Mrs Webster gave us.

Overall, we found out that little bugs have to be in the water for the water to be healthy. If they’re not, the water will not be healthy and plants and invertebrates won't be able to live in the water because they will die. But if you stop throwing rubbish, paint and car washing bubbles we will have healthy water and there will be living creatures in the water.
