Activities
01) Soil Moisture Field Study
In this field study, students use a soil moisture sensor and an on-board GPS sensor on their mobile device to determine the ability of soil to hold and absorb water across a transect of land based on a class set of measured volumetric water content (VWC) values and calculated infiltration rates.
02) Plant Growth and Water Content
Students use a soil moisture sensor to determine the ideal moisture level for optimum plant growth.
03) Soil Type and Surface Moisture
Students use a soil moisture sensor to determine the surface evaporation rate for three different soil types and a mixed soil sample.
04) Drinking Water Quality: Hardness
How are total dissolved solids (TDS) measurements used to evaluate drinking water quality? In this investigation, students use a conductivity sensor to relate total dissolved solids (TDS) measurements with drinking water quality. Students can compare treated drinking water with natural water sources.
