Protocol

Students will measure near-surface soil temperature frequently near local solar noon and seasonally throughout two diurnal cycles.

Supporting Protocols

Protocols to help in completion of the main 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.
Students log atmosphere data using a Davis automated weather station. A weather station is setup to measure and record atmospheric measurements at 15 minute intervals. These measurements are transferred to your school's computer and then submitted to GLOBE via email data entry.
Students use a digital multi-day maximum/minimum thermometer mounted in their instrument shelter to measure the maximum and minimum air and soil temperatures for up to six previous 24-hour periods.
Students will use a second digital multi-day maximum/minimum thermometer mounted in their instrument shelter to measure the maximum and minimum soil temperatures at 5 cm and 50 cm depths for up to six previous 24-hour periods.
GLOBE schools participating in the Earth Networks Schools Program arrange for their data to be transferred automatically to GLOBE. A special GLOBE Atmosphere Study Site is defined for the school's Earth Networks weather station, and this activates an automatic transfer of their Earth Networks data to the GLOBE database.
Students will use four temperature probes and a data logger to measure air temperature and soil temperatures at depths of 5 cm, 10 cm, and 50 cm every 15 minutes.
Measure the current air temperature when an instrument shelter is not available. Current air temperature is measured using a thermometer held in the open air but in the shade for at least 3 minutes.
Students log atmosphere data using a RainWise automated weather station. A weather station is setup to measure and record atmospheric measurements at 15 minute intervals. These measurements are transferred to your school's computer and then submitted to GLOBE via email data entry.
Students will use a technique chosen by their teacher to expose a soil profile for characterization.
Students log atmosphere data using a WeatherHawk automated weather station. A weather station is setup to measure and record atmospheric measurements at 15 minute intervals. These measurements are transferred to your school's computer and then submitted to GLOBE via email data entry.

Learning Activities

Activities to help students learn more about the instruments and protocols
Students draw a visualization and learn about all the design choices involved and how these choices affect what is communicated by the visualization.
Students use GLOBE visualizations to display student data on maps and to learn about seasonal changes in regional and global temperature patterns.
Students measure temperature change in soil, water and air as they are exposed to the heating action of the sun.
Students use visualizations to explore the relation between elevation and temperature and begin learning how to make important patterns evident in visualizations.
Students construct one or more contour maps using GLOBE data.
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 use GLOBE data and graphing tools to compare the influence of latitude, elevation, and geography on seasonal patterns.
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.
