We are learning about separating materials in science and this week we have been using the process of filtering to separate a variety of insoluble solids from water. The filter paper worked very well for most solids but when we filtered our mixture of compost and water, the result was still slightly brown. Some tiny solids must still have got through! You can see our results in the photo below. From the left – tap water, filtered compost and water, compost and water.
