First, we were able to join in an explanation of the water cycle and show how much we had learned already.
Then Mr Forbes explained the role of Wessex Water. The water collects in a reservoir and is directed to the water works where it has to be sieved and filtered to remove the debris. Then the exact amount of chlorine is added to make it safe. After lots of tests the clean water travels through underground pipes to our houses.
Next it was our turn to do some testing! Our job was to see if we could identify the origin of three water samples. We had to conduct a pH test, to find out if the water was acid, neutral or alkaline, a chlorine test and a hardness test to find the levels of minerals in the water.
From our evidence we deduced which sample was tap water, which was swimming pool water and which was rain water.
Mr Forbes then explained that a big problem for Wessex Water is blocked pipes. He made a horrible mixture of all the things we could think of that went down the drains from our houses!
He challenged us to think about which things could go into the sewers and which should be put in the bin instead.
Hands on time again!
We had three types of paper, water, bottles and sticks and we had to design and conduct a FAIR TEST to investigate which papers were suitable for flushing and why!
It was an amazing morning of discovery and we would like to say a big thank you to Mr Forbes from us all!
