Carolina Investigations® for AP® Environmental Science: Soil Productivity 1-Station Kit

(in stock)


Exploring different characteristics of soil provides insight into how productive it might be for farming purposes. Students conduct experiments on different types of soil to observe and measure properties such as water-holding capacity, ion-exchange capacity, macronutrient content, and particle-size distribution to determine which types soil are the most productive for growing plants. Students then test their hypothesis by planting alfalfa to track success.

This kit is designed for 1 group of 4 students. Digital teacher's manual, included FREE with kit purchase, is a 12-month eBook license to the Soil Productivity Teacher's Manual and Student Guide.
