This month’s blog is brought to you by Clare Docking, one of our advisory teachers who works with industry and schools in the East of England.
Children love to play with mixtures combining solids and liquids to make something different. In this activity we take this one step further and use filters to reverse this process and separate out the solid again. This investigation is easy to set up as it involves using everyday household materials for the filtering and uses a simple mixture of flour and water for the solution. Children will enjoy predicting which filter they think will do the best job of separating out the solid from the liquid and then testing to see if they are right. This activity will prompt them to consider the properties of materials and why some make good filters, and some don’t.
Three, two, one – investigate!
