Students explore the formation of soil and its physical properties when it reacts with water. During 2 lab periods, students investigate weathering of rocks, particle size composition of local soils, and the rate of permeability of different soil samples. They then apply their knowledge to construct a model of a slope that has been cleared for farming and design a plan that modifies the slope to reduce erosion. Kit includes enough materials for at least 30 students working in groups.

• Demonstrate soil characteristics with easy-to-perform activities
• Sample runoff water to quantitatively evaluate erosion control
• Relate soil properties to sustainable agricultural practices

Students explore the formation of soil and its physical properties when it reacts with water. Performing 3 different activities over 2 lab periods, students investigate weathering of rocks, particle size composition of local soils, and the rate of permeability of different soil samples. They then apply their knowledge to construct a model of a slope that has been cleared for farming and design a plan that modifies the slope to reduce erosion. Kit includes enough materials for at least 30 students working in groups. Receive a FREE digital Teacher's Manual and Student Guide with kit purchase.
