This week in science, Year 5 have been investigating how to separate mixtures.  We worked together to choose different approaches and use different types of equipment to separate a mixture of flour and oats (a sieve worked well), paper clips and sand (a magnet was useful) and finally sand and water.  For the last one we used filter paper as the fibres that make up the paper have holes which are so small, only the water can pass through and the sand gets left behind.
