soil white in dry areas). Soil colour also differs depending upon how wet or dry the soil sample is and can indicate if the soil has been saturated with water. Consistence Consistence relates to the firmness of the individual peds and how easily they break apart. A soil with firm consistence will be harder for roots, shovels, or ploughs to move through than a soil with friable consistence. Texture: The texture is how the soil feels. It is determined by the amount of <span class="highlight">sand</span>, silt, and clay

may also want to create a "worm farm." Place <span class="highlight">sand</span> and soil in horizontal layers in a glass jar. Use this to observe worm behaviour, decomposition, and changes in soil over a longer period of time. Ensure the moisture of the soil is maintained to avoid worm desiccation! • Do a similar experiment as above but vary the soil texture. Include jars with sandy soil and clay soil and observe differences as above. www.globe.org.uk Soil - 15
