Watercare with Sally.

On Monday a lady from watercare came to our class. Her name was Sally, she taught us where our poo goes and where water comes from. I thought poo went out to the sea but it actually goes to a huge factory. The poo gets eaten by little bugs, then the poo turns into acid. After awhile some other bugs eat the acid and there's electricity. They take most of the poo and dry then put it under trees, plants and grass. Our sewage water gets sent to the same factory. When water goes to the factory they clean it by sending it to these huge filters. Inside the filters they're these little bugs called superbugs, they drain out every dirty thing in the water. Then when they're full they take a little nap. After the water to our home to drink then the start the whole process again. Finally after we finished learning about water we actually did a little experiment. We had to make a group of 3 or 4. The group we made was Halatoa, Me, Joshua and Leenas. We had to number ourselves 1, 2, 3 and 4.  I was 1, Leenas was 2, Joshua 3 and Halatoa 3. Number 1 (me) had to fill the 4 cups to half way then come back. After I filled up the 4 cups the lucky ones number 2, 3 and 4 could put the food colouring in. The colours were red, yellow and blue. I had to wait for a long time but then I got to get these tubes and number 1, so the first one had the chance to make a colourful rainbow. I learnt that salt water is heavier than fresh water so the salt will sink right down to the bottom. And you might just might end up with drinking salt water.
