Freshwater Macroinvertebrates, Hydrosphere Field Guides
Freshwater Macroinvertebrates, Hydrosphere Field Guides
Students will collect, identify, and count macroinvertebrates at freshwater hydrology sites.
Freshwater Macroinvertebrates, Hydrosphere Protocol Instructions
Hydrosphere Protocol Instructions
Pedosphere (Soil) Learning Activities
Students make mud pies by adding water to the various soil components, letting them dry and observing the pie's characteristics.
Soil Characterization Learning Activities
Air Temperature, Atmosphere, Frost Tube, Pedosphere (Soil) Field Guides
Air Temperature, Atmosphere, Frost Tube, Pedosphere (Soil) Field Guides
Frost Tube, Pedosphere (Soil), Precipitation, Soil Temperature Data Sheets
Frost Tube, Pedosphere (Soil), Soil Characterization Field Guides
Students will construct a Frost Tube that is inserted into a hole in undisturbed and uncompacted soil. During the cold months, students measure the depth at which water in the Frost Tube has frozen, indicating that the surrounding soil has also frozen. Watch the Frost Tube Training Video.
Frost Tube, Pedosphere (Soil) Protocol Instructions
Frost Tube, Pedosphere (Soil), Soil Temperature Field Guides
Students practice the skill of estimating percent cover.
Biosphere, Carbon Cycle Learning Activities
Collect a random sample of herbaceous vegetation on a STANDARD SITE, and dry it in paper bags or a drying oven to measure biomass. *Can be done in conjunction with Tree and Shrub/Sapling STANDARD Protocols.
Biosphere, Carbon Cycle Protocol Instructions
Collect a random sample of herbaceous vegetation on a NON-STANDARD SITE, and dry it in paper bags or a drying oven to measure biomass. *Can be done in conjunction with Tree and Shrub/Sapling NON-STANDARD Protocols.
