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

A Carolina Exclusive! Grades 9-12. 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 lab supplies (enough for at least 30 students working in groups) plus teacher's manual. Kit Refill replenishes consumed materials. Multi Class Equipment Set provides additional lab supplies so you can use the kit in 1 additional class section per day.

Note: Order an extra kit refill for each additional class section. For example, to teach the kit in 3 environmental science sections on the same day, purchase 1 kit, 2 kit refills, and 2 multi class equipment sets. Part of the Inquiries in Science® series.
