We visited Room 7 because they had an expert scientist in ( Lochie's Mum!) who had shown them how you can make dirty water into water that you can drink!
Mrs Gunn had some really dirty water that was full of mud and stones.
Mrs Gunn decanted some of the water into one containter by tipping it down a galss rod and lots of the stones and dirt stayed out. So now there was a container with REALLY dirty water and one that was still dirty but had some of the muck out of it but we still decided we didn't want to drink it!
The Mrs Gunn and Claire folded a piece of filter paper ( like you use for coffee) into a cone shape and put them into two glass funnels.
Then Mrs Gunn poured the REALLY dirty water inot one and the not-so- dirty water into the other cone.
Slowly the water dripped through.
This is the water that had all the rocks and lots of mud removed.
This is the REALLY dirty water.
Look at all the mucky that was left in the filter paper.

| The water that had come through the filter looked clean enough to drink!! |
Thanks Room 7 and Mrs Gunn for sharing your learning with us.
