This week Mr Rose is teaching us about separation and filtration. We studied how we could clean up dirty water. This linked nicely to our WaterAid work. P2 learned that there is a lot of water in our bodies (as the picture below shows).
We filtered the sandy water through some gravel inside a filter paper. This is what we were left with after filtering:
Lots of sand was kept in the filter but the water was still quite dirty. It would take a lot more filtering to make this safe drinking water.
