Test your knowledge of soil moisture and its effect on global populations.  Soil moisture is the amount of water contained in the soil.

Background information on soil moisture.

In this activity, students investigate three different soil samples with varying moisture content. They use a soil moisture probe to determine the percentage (by volume) of water in each of the soil samples.

Students can interact with NASA data to build visualizations of monthly soil moisture data on a custom map or graph, using the Earth System Data Explorer.

GLOBE protocols and learning activities that complement the Soil Moisture phenomenon through hands-on investigations are detailed.
