IDL-water filtration challenge

P7G are transitioning from our ‘ultimate survivor’ to our ‘extreme earth’ context. The class were tasked with a science challenge to link the two….following a ‘catastrophic earthquake’ they had to hypothesise and then select the best materials to filter dirty water as a team to survive. It was a competition to get the best/clear visual result. Well done team 4! (Who didn’t spill or dye their water)! šŸ˜†
