Clean Water Challenge!

In their materials topic, Scafell have been looking at ways to separate mixtures. Having looked at the theory, today was our chance to put our learning into practice.

Our challenge was to take a jug of dirty water (complete with stones, mud & leaves!) and use the materials provided to separate the clean water out. Each team used a range of approaches, including sieving, filtering and decanting the mixture – sometimes a few times over – to end up with something that looked much cleaner!

Everyone worked extremely well as part of a team, and all teams made great inroads into purifying their water. Next up – why might this be useful? What situations can you think of where cleaning and purifying water would be useful?
