Important: This protocol has been deactivated and no new protocol measurements can be submitted to GLOBE's databases. For more information, check out the Deactivated Protocols page.
Protocol
Students install soil moisture sensors and temperature probes and connect them to a Davis Soil Moisture and Temperature Station. Data are logged every 15 minutes and periodically students transfer these data to a computer and report them to GLOBE.
Protocols to help in completion of the main protocol.

Students will use a technique chosen by their teacher to expose a soil profile for characterization.
Step-by-step instructions for collection data according to the protocols.
Sheets to be filled out during data collection.
Activities to help students learn more about the instruments and protocols.
Students discover that soil properties such as moisture and temperature can vary considerably across a single landscape.
Students make mud pies by adding water to the various soil components, letting them dry and observing the pie's characteristics.
Students are introduced to the basic concepts of how water passes through soil in an activity which illustrates the scientific method. More advanced students investigate the effects of soil characteristics on water infiltration and the chemistry of water that has passed through soil

Students collect, describe and compare soils from their own backyards.
Students will understand the geologic phenomena of weathering and erosion. These processes, along with deposition, shape our landforms and contribute to the development of parent material in the soil formation process.
Students simulate environmental conditions in order to determine the key factors that affect the decomposition of organic material in soil.
Students explore soil moisture by weighing and drying sponges and then they explore their soil samples in the same way.
Teams of students play a game in which they gather data and distort the values of certain measurements. They then estimate the values of the measurements taken by other teams and try to detect their errors.
An activity which highlights the importance of learning about the soils on Earth. In this activity students explore some of the many uses of soils, learn the five soil-forming factors, and gain a better understanding of how little of Earth's surface is covered in soil.
