The new ELI this week is 'Soil doughnuts; sorting out soils'
Give the pupils a variety of different soil types ranging from very sandy, through loam to heavy clay. They can then use the table provided to work out which soil type they have. They soon realise that sandy soils allow water through easily and clay soils do not. Gardeners usually prefer loam soils. For a farmer or gardener, it is important to know the soil type so that it can be managed properly and crop production increased.
Along with the other soils activities in the ELI soil series, this can be used in any lesson about the environment, rocks and landscape, agriculture, gardening or investigations out of doors. It is messy, but fun!
