Soil Experiments and Hands-on Projects. Use grape Kool-Aid to learn how "Soil is a Filter" and how important soil is for clean drinking water. Soil is made up of four distinguishable components--air, water, organic materials, and minerals. The average soils composition is 45% minerals, 25% water, 25% air, and 5% organic matter. Another soil property is texture. Soil texture is classified by the size of the mineral. Soil has many properties and are classified accordingly.
