Muddy Water Challenge

What is the best way to clean a jar full of muddy water?  Just ask the super scientists in Class 3!

They worked brilliantly in their teams: making careful observations; thinking critically about how they could make their filters better to make their water clearer and showing great patience while their filters worked like magic.

They quickly realised that the best results came with a combination of materials and they re-invented filter beds!  An afternoon well spent!
