We have been learning about what happens to dirty water and how it is made safe to use again.
We decided to try and filter some dirty water using different materials. We recycled drinks bottles by cutting off the top and turning it upside down (Miss Weatherall helped us with that!). We chose to use cotton wool, felt, a glittery fabric and paper towel and stuffed them into the neck of the bottles before pouring dirty water in the top. We couldn’t wait to see which bottle had the clearest water and the best filter.
The clearest water was filtered by the paper towel and the dirtiest water was filtered by the glittery fabric.
We love finding out by experimenting!
