In Lavender Class today we carried out an experiment to clean water. We learnt about what life is like for children in the Turkana region of Kenya and how they need to walk for miles every day to collect water which may not be clean.
Working as a team, we were given a mixture of 4 different substances – water, stones, salt and sand. We had to devise an experiment to clean the water only using the materials we were given. Having removed the stones using a colander, we then used filter paper to remove the sand. We now have a mixture of salt and water that we are hoping, through evaporation, will leave salt.
