separation of ironstone from soil
Shallow‐soil endemics: adaptive advantages and constraints ...
Ironstone communities are seasonally wet, shallow‐soil shrublands that contain many endemic species as well as species that have their distribution centred on them (Gibson et al., 2000). Field observations suggest that neither ironstone Hakea species suffers from reproductive constraints, as populations contain numerous, easily germinable seeds.

Activity: The JamJar Experiment
differing soil types earth from the school grounds and nearby areas for example. Try 'making' soil by mixing potting compost with playground sand to see it separated out again. It is good, if possible, to try samples of other soil types from the area – soils can vary enormously within a short distance. Label jars with the sources.

Separation and Purification of Bacteria from Soil
Bacteria were released and separated from soil by a simple blendingcentrifugation procedure. The percent yield of bacterial cells (microscopic counts) in the supernatants varied over a wide range depending on the soil type. The superantants contained large amounts of noncellular organic material and clay particles.
