Role play soil - Each person takes on a role of an element of the soil (e.g. clay/sand/silt particles, water, air, organic matter, plant roots, fungus, bacteria), then dramatise how those elements interact in different soils (e.g. compact, dry, wet, rich soil). Compacted soil has no air. At the end create a perfect mixture for growing which is 1/4 air, 1/4 water, 10% organic matter and 40% mineral.
