STEM Education project education features cracked soil and physical properties of soils have been factors in different environments with the aim to study the soil that are.Cracked can only be described by mathematical principles by collecting soil, loose, sandy soils and clays to simulate environments by splitting into four trial procedures include:1. touch the soil texture characterization 2. the study of moisture content and density of soil samples before cracked. 3. to study the behavior of cracked clay 4. to study the factors which cause the cracked soil. After the trial, found that the soil is imported it is a trial of clay soil. (Clay) soil (Loam) loose and sandy soil (Sand), the average humidity of clay average soil before cracked loose sand and soil in 0.1413 0.4933 0.0277 density of clay average before cracked 0.9423 kilograms per cubic meter. Loose soil 0.6437 kilograms per cubic metre and a sand 0.977 kg per cubic meter. The cracked soil usually occurs from the area that gets the most heat and cause a geometry which is usually caused by the edges of the container. A study of the factors which make the cracked soil, most outdoor sunlight, as well as the wind blows.
