We did the clean it up challenge under fresher water whereby 38 learners participated cleaning water using a filtration method with 2L bottles. Learners learnt how to filter water using various material, showing the learners easy ways to filter water and get rid of large and small sediments. The learners improved by gaining more knowledge on water and the importance of wetlands. The highlights was the effective filter the pink group was able to make using a carefully and well thought out construction of various layers of material. The learner are now very knowledgably about saving water and I found the lesson very interesting.
