Day 4

Washed Away: Climate Change and Farmland Soil Quality
 
Students see a demonstration of the erosion of topsoil on a farm by an extreme precipitation event and then use a soil nutrient test kit to conduct an experiment to analyze and compare the nutrients of the topsoil and lower layer.  Students also use SoilWeb, a web-based tool, to investigate soil characteristics of agricultural land in three areas and at their own location.
